Diamondback Firearms 7.62x39mm AR-15 Carbine Barrel Nitride - 10"
The Diamondback Firearms 7.62x39mm AR-15 Carbine Barrel is machined in house on state-of-the-art CNC machines and are thoroughly inspected at multiple stages of the build process to ensure quality. This 10” barrel is machined from 4150 Chrome Moly Vanadium Steel and is 6 groove button rifled to ensure consistent accuracy and has a 1:9.5 twist rate. The carbine length gas system is optimal for reliability with a short 7.62x39mm barrel. It is threaded 5/8x24 and features an 11 degree target crown. The final process is a salt bath Nitride finish for an added layer of protection.

<br>Bear Creek side charging upper and BCG, Anderson lower with PSA EPT trigger, KAK shockwave buffer tube kit with a Strike Industries brace/blade, C-products 28rd 7.62x39 mags.
<br>It's a fairly accurate barrel (1" groups at 50 yds). No failures to feed, fire or eject out of multiple C-products mags with Tula 122gr FMJ.
<br>It's a jam-o-matic with the Tula 124gr 8M3 HPs. It looks like the bottom lip of the HP is getting caught on the feed ramp as it chambers. Presentation angle from the magazine looks good, so it appears to be a problem with how the ramp and the HP tip are interacting. It occurs primarily with the right feed ramp (viewed from the butt).
<br>I haven't had the chance to try SPs or other brands of HPs . I'm bummed that it doesn't like the primary ammo I hoard for my AK. It's hard for me to recommend it if it doesn't feed everything that it's presented with. Maybe the problem lies elsewhere, but doesn't look like it. YMMV.
