Description
The Bravo Company Gunfighter Mod 0 SOPMOD Stock Kit takes one of the toughest polymer stocks on the market and pairs it with all the internals you need to finish an AR-15 lower. This is the widebody SOPMOD version, which means a fatter, more pronounced cheekweld that helps you settle behind an optic and stay consistent shot to shot. BCM spent over a year designing and testing this stock, and it shows in the fit and finish.
What Sets the BCM Gunfighter Mod 0 SOPMOD Apart
The body is molded from a durable, lightweight polymer with a snag-free profile, so there are no sharp edges to catch on a sling, plate carrier, or MOLLE gear when you shoulder up or transition. A color-matched rubber butt pad keeps the stock planted on your shoulder and adds a little extra durability where it counts. One feature people tend to overlook is the integrated VBOST, or Vehicle Borne Operations Sling Tab, which lets you use a ranger band or bungee to pin your sling tight against the stock when the rifle is slung and not in use.
Sling Options Built Into the Gunfighter Stock
You get two different ambidextrous sling mounting setups, including QD swivel sockets, so you can run whatever sling style you prefer without adding extra hardware. The simple modular design uses a handful of parts and a single screw, which makes it easy to work on and leaves the door open for future configuration swaps down the road.
Because this is the full kit and not just the stock, you can build a bare lower from scratch or retrofit an older fixed-stock rifle in one shot. All BCM parts are made in the USA, and the company has earned a strong reputation for tight tolerances and quality control. Folks who run it consistently point out the snug, wobble-free fit and a cheek weld that rivals stocks costing quite a bit more.

Frequently Asked Questions
Does the BCM Gunfighter Mod 0 SOPMOD kit include everything I need to finish a lower?
Yes. The kit comes with the stock, a 7075-T6 mil-spec receiver extension, castle nut, carbine action spring, carbine buffer, and a QD swivel mount end plate. That covers everything you need to complete a bare lower or retrofit a rifle that has an older fixed stock.
Will this stock wobble on my buffer tube?
The Mod 0 SOPMOD is known for a snug, tight fit with little to no rattle, and it comes with BCM's own mil-spec tube in this kit. Some people find it fits a touch snug at first, which most see as a plus since it locks up solid once seated.
What is the VBOST on the Gunfighter stock for?
VBOST stands for Vehicle Borne Operations Sling Tab. It gives you a spot to run a ranger band or bungee that pins your sling against the stock when the rifle is slung and not in use, which keeps things tidy when you are moving around or seated in a vehicle.
What makes the SOPMOD version different from a standard Mod 0 stock?
The SOPMOD is the widebody version, so it has a fuller, more pronounced cheekweld than the standard Mod 0. That extra width gives you a comfortable, repeatable surface for your cheek, which helps with consistency behind an optic.
