The BCM Gunfighter Stock Mod 0 is a collapsible Mil-Spec carbine stock for AR-15 and M4 rifles, fitting any Mil-Spec-diameter carbine receiver extension.
A carbine stock designed by people who fight with carbines — the BCM Gunfighter Mod 0 does everything a duty stock must.
The BCM Gunfighter Stock Mod 0 pairs a snag-free, ergonomic silhouette with the sling integration professionals actually use: ambidextrous QD sockets plus traditional loops, so any sling rigs cleanly for either shoulder. The fit on a Mil-Spec receiver extension is deliberately snug — minimal play, no rattle — and the cheek weld surface is broad and consistent for fast, repeatable mounts.
High-impact polymer construction shrugs off the drops, strikes and weather of hard training. Like everything Bravo Company USA builds, it is made in the USA to fighting-rifle standards, not hobby-grade ones.
Fits AR-15/M4 rifles running a Mil-Spec-diameter carbine receiver extension — tool-free slide-on installation. Commercial-diameter tubes are a slightly larger outside diameter and will not take it, so check your tube specification before ordering, or measure it if the build history is unknown to you. Sling and QD swivels are supplied separately.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging.

It fits AR-15/M4 rifles running a Mil-Spec-diameter carbine receiver extension. Commercial-diameter tubes are a slightly larger outside diameter and will not take it. Check your tube specification before ordering, or measure it if the build history is unknown to you.
The main practical difference is the lock-up: it uses internal tension against the tube so the stock sits solidly rather than rattling at each position. It is moulded from high-impact polymer and keeps a fairly conventional carbine profile, so it does not change your cheek weld much if you are coming off a mil-spec stock. It is the plainest of the Gunfighter stocks, without a storage compartment.
It has ambidextrous QD sockets as well as sling loops, so you can run either a QD swivel or a loop of webbing and switch shoulders without re-rigging. That covers most one and two point sling setups. You will need to supply the sling and QD swivels separately.
The stock is offered in Black and Flat Dark Earth. If you do not already have a Mil-Spec carbine tube, buffer and spring, the <a href="/products/bcm-gunfighter-stock-kit-mod-0-sopmod">Gunfighter Stock Kit Mod 0 SOPMOD</a> includes all of that in one purchase.
