You get the Mil-Spec 6-position receiver extension machined from 7075-T6 aluminium, the receiver end plate, the M4 castle nut, the carbine action spring and the carbine buffer assembly. Bolt those to a lower receiver and you have everything a Mil-Spec stock needs to slide onto — except the stock.\u003c\/p\u003e\u003cp\u003eThat makes it the right purchase when you already have a serviceable stock and want fresh, correctly specified hardware behind it, or when you are building a lower from parts and want the tube assembly from one manufacturer. \u003cstrong\u003eIf you want the stock as well, the \u003ca href=\"\/products\/bcm-gunfighter-stock-kit-mod-0-black\"\u003eGunfighter Stock Kit Mod 0 in Black\u003c\/a\u003e is this same hardware supplied with the Mod 0 stock fitted.\u003c\/strong\u003e Ordering this kit expecting a stock is the single most common mistake on this part, so it is worth a second look before you check out.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the Milspec Carbine Stock Hardware Mounting Kit\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware only, priced accordingly\u003c\/strong\u003e — you are not paying twice for a stock you already own\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7075-T6 receiver extension\u003c\/strong\u003e — 6-position, machined to Mil-Spec dimensions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete assembly\u003c\/strong\u003e — tube, end plate, castle nut, action spring and buffer in one box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched components\u003c\/strong\u003e — spring and buffer specified together rather than mixed from a parts bin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad stock compatibility\u003c\/strong\u003e — takes Mil-Spec stocks from a range of makers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the Milspec Carbine Stock Hardware Mounting Kit fits\u003c\/h3\u003e\u003cp\u003eFits AR-15\/M4-pattern lower receivers with a standard threaded rear, including UK straight-pull AR-15 builds, where the buffer and action spring return the carrier after each hand-cycled stroke. Bravo Company USA lists the kit as compatible with Mil-Spec dimension stocks from BCM, VLTOR, LMT, Magpul CTR-M, Stag Arms and Colt. Because the receiver extension is Mil-Spec diameter, a commercial-diameter stock will not fit it. Remember that no stock is supplied: you must already have one, or buy one separately. Fitting needs a castle-nut wrench, and the castle nut should be torqued and staked or thread-locked.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePlatform\u003c\/th\u003e\n\u003ctd\u003eAR-15 \/ M4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eAR-15\/M4 lower receivers with a standard threaded rear; Mil-Spec dimension stocks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eStock mounting hardware — receiver extension, receiver end plate, castle nut, carbine action spring, carbine buffer.
