Featureless AR-15 Rifles [2018]: California Build Guide

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 (in California) is one that does not have any of the following:

  • pistol grip
  • thumbhole stock
  • telescoping/folding stock
  • flash hider
  • grenade or flare launcher
  • forward pistol grip

A featureless rifle allows the use of detachable magazines and lawfully owned standard-capacity magazines.

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.

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.  In 2018 you’ll need more than a simple tool…read on!

  • 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…

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 were scheduled to become illegal in CA on July 1, 2017 but the law was blocked by a judge.

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.

General

  • 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 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 a family member 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.  No more a simple pin into the bullet button.
  • If I had to choose one right now I’m leaning towards the Patriot Mag.  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?

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

Futureless Muzzle Devices

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

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

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).

Featureless Grips

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 most of my featureless builds since it lets you have a hunting rifle grip.  Looks funky, but less funky than the other examples.  ($30)

Thordsen FRS-15 Stock: Complete kit to solve the issues of the pistol grip and a telescopic buttstock.  Generally in stock these days, but that can change often. ($140)

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

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.  More models and upgrades in our Best AR-15 Upgrades section.  I like the Seekins.

Strike Industries Megafin: A recent addition to featureless grips and my current favorite.

Has a place to put your thumb so you get a lot more stability especially when moving around.

One thing to keep in mind is that you’ll probably lose the ability to have a regular ambidextrous safety since your thumb is in the way.

Update…I’ve built another rifle with the Megafin and combo-ed it with the Seekins’ Ambi Safety.  I turned it around and ground off the sharp arrow.  Now I flip up with my right hand to disengage and press down to engage the safety.

Featureless Stocks

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)

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

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.

Stock Lok: Something new has come out that swaps out the spring-loaded adjustment pin for something fixed.  More expensive at $35 but you don’t need to drill and pin.

Strike Industries Stock Stop: The newest thing out…

You cut the rubber piece so that it fits your buffer tube and only shows one hole.

And slip on your regular stock until it clicks in that hole.  Voila…fixed stock!  Only thing is you can’t select a custom length since there’s that stopper in the front.  Make sure the 2nd to last hole works for you.

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)

Best New “Bullet Buttons” for 2018

Even though this article is about featureless…I know you want to know about the best new “bullet buttons.”

Current law makes it ok if your magazine is fixed and the upper/lower receiver halves are opened up in order to release the magazine.

The best “new” bullet button I like is the AR MagLock + Patriot Pin.

AR Maglock and Patriot Pin Combo
AR Maglock and Patriot Pin Combo

Pretty easy to install (especially if you’re building) and really quick mechanism to release the rear due to the Patriot Pin.

Full review here.

And here it is in action for a tactical reload.

Regular empty mag reloads take a little longer you’ll see in the review.

Another slick solution (but requires sending in your lower) is the Battle Arms Development MRB (magazine release block) combined with their special rear takedown pin that opens up the upper/lower halves just enough:

Best solution: Get the fuck out of this sick fucking police state run by communists

Or we could just stand up like we all had balls, and tell them what to do with their stupid, unconstitutional bs laws. But I guess pride in America and standing up for what’s right died out with the Greatest Generation.

Would building a “featureless” rifle as you described here also be Connecticut legal?

So you give in to what they want rather than fight back Seems most have forgot what the guns were truly for.
