Featureless AR-15 Rifles [2017]

Confused by all these new laws and what makes an AR-15 “featureless” so you might not have to register it as an assault weapon (AW)?

A featureless rifle is one that does not have any of the following: pistol grip, thumbhole stock, telescoping or folding stock, flash hider, grenade or flare launcher, or forward pistol grip.  A featureless rifle allows the use of detachable magazines and lawfully owned standard-capacity magazines.

*UPDATE* March, 2017 with a TLDR section on the new California Assault Weapon laws + favorite new bullet button.

A little confused?  We’ve got you covered.

Learn exactly what makes an AR-15 “featureless,” how it allows the use of the magazine release and larger magazines, and how to build one with recommendations for appropriate grips, stocks, and muzzle devices.

Plus where to buy fully-assembled featureless rifles so you can still get AR-15’s in CA and NY.

Disclaimer that this is not legal advice and you should double-check everything, especially since the laws surrounding this always seem to be in flux.  I’m also writing this mostly towards residents in California, but New York residents can also benefit.

What Makes an AR-15 “Featureless”

First, let’s go over what makes an AR “featureless” before diving into the laws.

This flowchart from Calguns.net is perfect for making sure your semi-auto centerfire rifle is legal.

This works for other semi-auto centerfire rifles but I’m using the example of the AR-15 since it’s the most popular.

Please download the flowchart as well as following along with my emphasis edits (in poop brown) below:

Calguns Flowchart Brown
Calguns Flowchart Brown
  • Start: Begin here and if you bought your rifle at a legit FFL, it should pass everything with flying colors as you move down with the brown line.
  • Section A: Here is where it gets interesting for rifles…whether or not it can have a detachable magazine.  Most FFL bought new rifles take the “No” detachable magazine path to Section B.
  • Section B: You might have heard of the term “bullet button” which is just a branded name for magazine locks that require a tool (and a bullet is considered a “tool”) to remove the magazine.  When you just use your finger…you cannot release the magazine like normal.  The .gif shows some ingenuity in adding a little protrusion to the bottom of a magazine to active the bullet button.

  • Section C+D: This is where “featureless” comes into play since we will not have the features dictated in CCR 11 § 5469 and Penal Code § 30515.  
    • Pistol Grip
    • Thumbhole Stock
    • Folding/Telescoping Stock
    • Grenade Launcher or Flare Launcher
    • Flash Suppressor
    • Forward Pistol Grip

Still with me?

Things You Can’t Have on a Featureless Rifle

Pistol Grip

What you see on all normal AR-15’s.  It allows you to hold it in a pistol fashion where the web between the thumb and the finger rests below the exposed trigger when firing.  Yea…I had to think about that for a minute too.

Thumbhole Stock

This monstrosity below is an example of a thumbhole stock where the thumb of the trigger hand can go through the stock when firing.

Folding/Telescoping Stock

The folding stock allows you to fold the stock over to the side so the overall gun is much smaller when not in use.  While the telescoping stock is very standard and more often known as a collapsible stock.

Grenade Launcher or Flare Launcher

The big tubes underneath the standard barrel.  Not seeing a whole lot out there, so yea…

Predator Grenade Launcher

Flash Hider/Suppressor

Device attached to the front muzzle that reduces the flash from shooting.  They are mostly for preventing the user being blinded by the flash at night, rather than hiding the flash from spectators, although that happens too.

There’s a lot of muzzle devices, and the big difference is that flash suppressors have a bigger cavity at the exit end than the bullet caliber when compared to muzzle breaks or compensators.

Flash suppressors usually come in two flavors…birdcage and multi-prong.

Forward Pistol Grip

Commonly known as the vertical foregrip since they can be grasped in a pistol-like fashion.

Why Would I Want a Featureless Rifle?

Seems like you miss out on a lot of cool stuff, so why would you want a featureless AR-15?

The big reason was hidden above in Section A…the ability to not have a bullet button and use your magazine release as it was intended.

And for those who have standard/high-capacity magazines, you are only allowed to use them in “featureless” builds.  Bullet-button rifles have a maximum of 10 round magazines.

However, this is set to change in California with the new Gunmageddon Laws.  Now the primary bonus of making a featureless rifle is so you do not have to register it as an assault weapon.

Those standard/high-cap magazines I talked about above…they are illegal in CA as of July 1, 2017.

California Assault Weapon Laws (2017)

Oprah, You're a Felon
Oprah, You’re a Felon

Again, I’m not a lawyer and this is not legal advice.  Also, this doesn’t cover all the “Gunmageddon Laws,” just the main ones that deal with AR-15’s and featureless rifles.


  • As of January 1, 2017, you can no longer buy/make/import the standard bullet-buttoned AR-15 as we know it since it is now an assault rifle.  The definition of a “fixed magazine” was changed from having to use a tool to something that requires disassembly of the firearm action.
  • For those of you who got one before…you have until January 1, 2018 to either register it as an assault weapon or make it featureless.  Or you can also surrender it, sell it outside of CA, etc…basically stuff you probably don’t want to do.
  • Registration is here (currently not up) and costs around $20.
  • If you register, there’s all sorts of fun things that come along with it…travel restrictions, inability to sell in CA, inability to lend, inability to transfer to family even if you die, etc.  Essentially it will die with you.
  • However, if you make a registered assault weapon (RAW) into a featureless one, you should be able to “de-register” it later.
  • More info here and here.

Featureless & Best New Bullet Buttons

  • You can avoid registering as an assault weapon if it no longer meets the requirements…aka a “featureless” build.  Find out how to do that after this law section.
  • You should also be able to keep the evil features and not register if you adhere to the new definition of “fixed magazine”…aka use one of the new bullet buttons that require disassembly of the action such as the Patriot Mag Release and the ARMagLock.
  • If I had to choose one right now I’m leaning towards the Patriot Mag…but I’d like to wait and see what happens to the laws near the end of 2017.  Since you have until Jan 1, 2018 to register or put on the new kind of bullet button.

AR Pistols & 80%-ers

  • AR pistols must follow the new laws PLUS not have a threaded barrel nor handguards.  So you’ll have to pin/weld an approved muzzle device and somehow not have handguards.  Basically…you’ll have to register or use the new type of bullet button.
  • 80% builds are still legal.  But you have to stay afloat the new laws.  Any new builds cannot be made into an AW.  AB 857 requires that by Jan 1, 2019 all completed firearms have a serial number.  If you engrave prior to July 1, 2018, you do not need to notify any government entity.  But if you do it after, you’ll have to apply to the state (pay fees, get a serial number, etc).  More info here.

Ready to build or upgrade (or rather…downgrade) to one?

How Do I Build a Featureless AR-15 Rifle?

Let’s go through each of the features again with our suggestions of how to make them compliant.

Featureless AR-15 Rifle
Featureless AR-15 Rifle

A. Flash Hider/Suppressor

On the easier side to fix…just don’t have one.

Opt for a muzzle brake/compensator instead.

If it talks about flash hiding or suppressing in the description, just err on the safe side and don’t get it.  Here are three of our favorites that did really well in this muzzle device shootout.

Precision Armament M4-72 Severe Duty: #1 in reducing recoil.  ($90)

Precision Armament M4-72 Severe Duty
Precision Armament M4-72 Severe Duty

Miculek Brake: Probably the best bang for the buck.  And boy, is it going to bang the eardrums of anyone caught to the side of you.  ($49)

Hybrid Compensator and Muzzle Brake
Hybrid Compensator and Muzzle Brake

I also really like Strike Industries’ J-Comp since it was super effective in the test and also one of the cheapest.  However, there were rumors that it was a flash hider.  I spoke with the company and they said there was a packaging error that stated it did have flash hiding capabilities…which is why came out with their J-Comp V2 ($35).

J-Comp vs J-Comp V2 (Installed)

B. Pistol Grip

The biggest aesthetic and functional change you’ll do in your quest to go featureless.

It might look really odd/ugly, but I’ve found that I quickly adapted to the different grip (almost like a hunting rifle grip) and I don’t find myself at a disadvantage during a match.

Exile Machine Hammerhead Stock: What I use in my featureless builds since it lets you have a hunting rifle grip.  Looks funky, but less funky than the other examples.  ($30)

Hammerhead Grip

Thordsen FRS-15 Stock: Complete kit to solve the issues of the pistol grip and a telescopic buttstock.  Pretty much out of stock in most places.  ($140)

Thordsen FRS-15 Stock
Thordsen FRS-15 Stock

Shark Fin Grip: A less permanent modification where you simply wrap the Kydex around your existing grip (lots of models available).  ($29)

Shark Fin Grips

Ambidextrous Safety: Highly recommended since all your fingers will be on the right side of the gun so it will be more difficult to engage and disengage the safety. ($18).  More models and upgrades in our Best AR-15 Upgrades section.

C. Stock

Many internet people say you can blind pin and epoxy your current collapsible stock so that it can no longer move, but again, I like to err on the safe side with a fixed stock.

Magpul MOE Fixed Stock: What I used to run in my featureless rifle.  Affordable, sturdy, and there’s no questioning that it is fixed.  Another source.  ($28)

Magpul Fixed Stock

A2 Buttstock: Very standard A2 buttstock for a more retro look and with storage compartments.  ($60)

A2 Stock
A2 Stock

Ace Skeleton Stock: One of the lightest stocks out there but still with tons of strength.  What I plan on using in my next competition build.  ($90)

Ace Skeleton Buttstock

Blind Pinning and Epoxying: If you really love your current buttstock or really want to save money, you can go ahead with blind pinning and epoxying your buttstock.  All it takes is drilling through the buttstock and some of the buffer tube, putting in a roll pin, and epoxying it over.  Some people even do it on both sides as an extra measure.

Drill Through Stock and Buffer Tube

I detail what I did for a new build here: How to Blind Pin an Adjustable Stock

Thumbhole Stock, Grenade/Flare Launcher, Forward Pistol Grip

These last three are easy to take care of…just don’t have them!  There’s some debate on whether or not the Magpul AFG is considered a forward pistol grip, but again…I’d just be safe and not have it.

Magpul AFG: Probably not a forward pistol grip since it’s more angeled…but why risk it.  ($33)

I Give Up…Where Can I Just Buy One

There’s a bunch of manufacturers jumping on the featureless train to get CA and NY purchases.  I’m waiting on them to come into stock so I can play with them hands on.

In the meantime, one I had a chance to use at SHOT 2017 was the Stag.

Stag 2TF Featureless AR-15
Stag 2TF Featureless AR-15

The Model 2TF ($1095) takes care of the pistol grip and buttstock all at onceand a removable plate allows use of the pistol grip if you are in a free state.  More models (even lefty ones) available at their site.

*Note* Unfortunately Stag no longer sells featureless models at this time.  I will update when they do again.

And again…the best “new” bullet button I like is the Patriot Mag ($45).


So there you have it, how to make a “featureless” AR-15 or other rifle in California/New York.

Good writeup, thanks. The photo you show for the Miculek shows top vents.. The link supplied with the photo takes you to a DPMS Miculek brake without ports on top. Where did you get the photo with the top vents? I have the same one and trying to track origin.

The author of the original article is *way* overdue for an update on this topic.

John Weaver

so Californians let themselves be disarmed by the legislature for their own safety?
How is it that letting the bad actors outgun citizens and their families with:
1.) more rounds per clip
2.) faster reloading,
3.) easier to handle and safer firearms
4.) readily available ammo – no 6 month waiting period for DOJ to approve ammo purchases. Wait til it’s in effect then see how long background checks for ammo will take.
those legislators need to be hauled out into the public square and beaten to a pulp..

Has anyone in California examined the effectiveness of the current laws and made at least a token effort to project how these new draconian infringements on California citizens’ constitutional rights will reduce violent crime? No, of course not. That would shine the bright light of reality on the lies perpetrated by those who want power, absolute and unchallenged. Why not look at Australia and see how effective their much-touted gun laws have been in accomplishing their purported goals? When are the majority of Californians going to stop letting a minority of the population (read as the political elites) take away… Read more »
“When are the majority of Californians going to stop letting a minority of the population (read as the political elites) take away any more of their Constitutional liberties?!?” The problem, I believe, is that the San Francisco Bay Area, Los Angeles, Orange County, San Diego, and the suburbs that surround these areas make up most of the population of the state and those urban areas are predominantly liberal so they support politicians like Gerry Brown, Gavin Newsom, Diane Feinstein, etc. The media plays to the crowd, so it just keeps getting worse. If there was something the rest of us… Read more »

I have a Kriss Vector.45 carbine, how to make it featureless ? ( Just the pistol grip needed to be changed )


Thank you for the writeup. Any updates on whether the J-Comp v2 is considered CA compliant?
