# New Product Highlight: Sig Sauer MCX-LTAW

About a decade ago, we all had to watch from the sidelines as Sig Sauer competed for a Joint Special Operations Command contract with the Low-Visibility Assault Weapon, or LVAW. In the near future, you’ll be able to get your hands on something very similar: the **Sig Sauer MCX-LTAW**.
It’s a mashup of some new parts and some existing components. Let’s break it all down so you can add it to your wishlist.
Sig Sauer MCX-LTAW Specs & Features
---------------------------------------
#### **Specs**
- **Caliber:** .300 Blk
- **Action:** Semi-automatic, piston
- **Capacity:** 30+1
- **Barrel Length:** 6.75”
- **Overall Length:** 31” (22.3” collapsed)
- **Weight:** 7 lbs
- **Country of Origin:** USA
#### **Features**
- Available as a pistol, SBR, or suppressed SBR
- Suppressor-compliant handguard comes standard
- Fully ambidextrous controls
Alphanumeric naming can be tricky (why not just call it the Black Mamba and go all-in on the vibes?), so here’s what all those letters mean:
- **MCX:** Sig’s rifle-caliber modular platform characterized by a short-stroke piston and dual recoil springs.
- **LT:** Ambidextrous controls.
- **AW:** A throwback to the LVAW.
So, as you can see, this is basically a Gucci’d-up SIg Sauer MCX-LT. In addition to the ambidextrous controls, the MCX-LTAW features an old-school angled pistol grip, two-stage match trigger, and a suppressor-friendly handguard for that ultra-cool tucked look.
The MCX-LTAW is chambered for .300 Blk and comes with one third-gen Magpul magazine.
There are three versions to choose from. The most accessible are a pistol with a brace and faux suppressor, and an SBR with a stock and faux suppressor. The big dog is an SBR with a stock, a Sig Sauer SQX suppressor, a Romeo4T-Pro red dot, and an Arisaka handstop, indexer, light mount, and QD mount.
