AR-15 pistol build kits chambered in 7.62×39 — the AK round in a compact AR pistol (AR-47). Each kit includes a short barreled upper (10.5″), handguard, gas block, muzzle device, a 7.62×39 bolt carrier group, charging handle, pistol buffer setup, and lower parts kit. These kits ship without a lower — pair with a finished AR-15 lower. No brace or sights included. 7.62×39 uses a caliber-specific bolt and magazines — see the FAQ.

Choosing a 7.62x39 Pistol Kit

7.62x39 gives a compact AR pistol inexpensive, widely available ammo, but the tapered case means a couple of parts differ from a 5.56 build. Here's what matters.

What's in the kit

A short barreled upper (barrel, handguard, gas block, 7.62x39 BCG, charging handle), pistol buffer parts, and lower parts kit. These are "no lower" kits — add your own lower. No brace, no sights. Contents vary by kit — check the listing.

Bolt and magazine compatibility

7.62x39 uses a caliber-specific bolt (different case head than 5.56) and 7.62x39-specific magazines for reliable feeding of the tapered cartridge. These kits include the correct bolt carrier group; plan to run 7.62x39 magazines rather than standard 5.56 mags.

Frequently Asked Questions

Do I need a special bolt for a 7.62x39 AR?

Yes — a bolt made for the 7.62x39 case head, not a 5.56 bolt. These kits include the correct bolt carrier group.

What magazines work with 7.62x39?

Magazines made for 7.62x39 — the taper causes feeding problems in standard 5.56 mags, so use 7.62x39-specific magazines for reliability.

Are AR pistols legal / do you need an FFL?

It depends on configuration and where you live, and the rules around AR pistols, braces, and unfinished receivers have changed and continue to evolve. Confirm current federal and state law and how a specific kit ships before ordering. General information, not legal advice.
