2021年8月20日 · The 9x39 using a 286 gr bullet at 1050 fps has 697 ft lbs of energy. For even another comparison, a 45acp using a 230 gr bullet traveling 900 fps only has 413 ft lbs on target. I don't say that to take away from 45acp because I love the 45acp.

2019年7月28日 · The case taper of 9x39 should be fine with existing AR-15 magazine taper, it's the fat bullet that needs to be addressed. Not sure if grinding the internal ribs will work. I have a 9x39 AK magazine from Csspecs too, just waiting for someone to start selling AK barrels.

2021年3月13日 · Note: About AR mags and loading them with 9x39, the approximate tipping point is at the shoulder of the rnd, and against the false 5.56 bullet mold on the shoulder of the follower, so if you broke off the head of a q-tip and placed it in the back of the mag on the follower and load a round on top of it, this keeps the bullet nose down and the ...

2018年3月9日 · It's the KS47. Uses proprietary upper but regular AR barrels. Bolt carrier is proprietary due to increased size of AK mags but the bolt itself is a regular 7.62x39 AR bolt IIRC.

2024年3月3日 · 9x39 can push a 280+ grain projectile very quietly, and it hits very hard. There have been several threads here discussing builds and load development. I know there are a few boutique loaders doing custom runs of 9x39. Ammo is still hard to find, and the stock of already imported 9x39 will dry up at some point.

2019年12月25日 · With the 7.62x39 magazines, caused the bullets to stack too far out to the side, causing swelling, but D&H is releasing their 9x39 magazine at shotshow this week so it should be resolved. I remember when 6.8 spc and 6.5 Grendel and even 7.62x39 AR franken mags went through the same growing pains.

2018年3月28日 · Wiki lists 9x39 as being 9.26mm or 9.25mm in diameter depending on bullet type for service ammo. I'm wondering if there is enough clearance on US 9mm suppressors to squeak by on the Wolf AR barrels about to come in or would it be wiser to go with a larger can (especially if 9x39 AKs ever come to market).
