Description
Bravo Company's BCMGunfighter Stock Kit Mod 0 takes the guesswork out of finishing off a lower receiver. Instead of buying a stock, a buffer tube, a castle nut, a buffer, a spring, and an end plate separately and hoping they all play nice together, you get the whole rear assembly matched and ready in one package. Drop it on, torque the castle nut, stake it, and your buffer system is done. It fits any AR-15 lower threaded for a standard mil-spec carbine buffer tube.
Why the BCMGunfighter Mod 0 Stock Earns Its Reputation
The stock body is molded from a strong, lightweight polymer that BCM calls the strongest of its kind for a mil-spec receiver extension. The snag-free profile is the real story here. There are no sharp edges or protrusions to catch on your sling, plate carrier, MOLLE gear, or anything else riding on your kit. An integrated color-matched rubber butt pad keeps the stock planted on your shoulder and adds a bit of durability where the stock takes the most abuse. Folks who run these tend to note how tight and rattle-free they lock up, with a comfortable cheek weld that holds position shot after shot.
Sling Options and the VBOST on the Mod 0 Kit
Running a sling is easy no matter which side you favor. The stock offers two ambidextrous mounting styles, including QD swivel sockets, plus the modular VBOST (Vehicle Borne Operations Sling Tab). The VBOST works with a ranger band or bungee to pin your sling against the stock when the carbine is slung and out of the way, which comes in handy inside a vehicle or moving through tight spaces.
What Comes in the BCMGunfighter Stock Kit
This is a genuinely complete package. Inside you'll find the Mod 0 stock body, a BCM 7075-T6 mil-spec receiver extension, an M4 locking castle nut, a mil-spec carbine action spring, a carbine buffer, and a BCM QD swivel mount end plate. The simple modular design uses just a handful of parts and a single screw, which leaves the door open to swap or reconfigure down the road. For anyone building or refreshing an AR-15, it's a clean, no-nonsense way to get a dependable stock and buffer setup in one shot.

Frequently Asked Questions
Does the BCMGunfighter Mod 0 Stock Kit include everything I need to finish my lower?
Yes, from the receiver extension back it's all here. You get the Mod 0 stock, a BCM 7075-T6 mil-spec buffer tube, castle nut, action spring, carbine buffer, and QD end plate. All you supply is the tools and the receiver.
Will this stock kit fit a commercial-spec buffer tube setup?
No. This kit is built around a mil-spec carbine receiver extension, so it fits AR-15 lowers threaded for the standard mil-spec tube. Since the kit already comes with its own mil-spec buffer tube, you'd be installing the whole assembly rather than sliding the stock onto an existing commercial tube.
How does the stock attach a sling?
The Mod 0 gives you two ambidextrous options. There are QD swivel sockets for a quick-detach swivel, plus the modular VBOST that lets you secure a slung carbine with a ranger band or bungee. That covers most sling setups regardless of which side you run.
What tools do I need to install the BCMGunfighter Stock Kit?
You'll want an armorer's or castle-nut wrench to torque the castle nut and a way to stake it once it's tight. A torque wrench helps you hit spec so the assembly stays put under recoil. Beyond that, installation is straightforward and the modular design keeps things simple.
