    9x39 10.5" Barrel works well

    Posted by Dee on December 17, 2019

    Barrel installed without issue on my upper. This build utilized a KS47 lower, CSSPECS 9x39 AK mags and a 45 cal suppressor. In order to reliably cycle with Tula 245gr subs I needed to swap the buffer spring to a reduced force spring (-20%) and removed the internal weights from the buffer to bring the buffer weight to 1oz overall. Having done that the gun cycled flawlessly and was ~2moA at 100yds with the Tula ammo. Extremely quiet suppressed.

    I'm very impressed with this combination!!

    bought this in the Hope's of building a AR pistol in 9x39 . well I have to say I'm very impressed with the results.!! I first tried accuracy with the gun itself and at 50 yards I was all but putting the rounds through the same hole with the gun in a rest. I did have some short strokes at the beginning, but seemed to improve as I shot it more and more. here is where I thought things were going to get interesting. I bought a Roni 5/8 x 24 3 lug adapter. I was concerned with my accuracy going away. but surprisingly it didn't change 1 bit . then I added a silencerco Hybrid with a 3 lug attachment. After I did that I had zero issues with any functioning what so ever. it ran perfectly!! and once again accuracy or point of aim didn't shift at all!! this is by far the cheapest way to build a 9x39 gun I could find . And I'm so glad I did it !! as quick note you must use 7.62m2x39 mags for this caliber.

    9x39 10.5 barrel

    Posted by DaBishop on February 26, 2019

    Quality barrel leaves single holes on paper. When used with the 278gr wolf ammo and a rugged obsidian with 9mm cap its a wonderfully quiet heavy hitter that stops pigs in their tracks. Works much better than the 300blk at pig stopping and reaches out much further than the .45 AR with in the heavy bullet dept, even more so than my 50 beowulf. A great barrel in a caliber that’s catching attention and gaining ground for mass appeal. I may have to retire my 300blk 8.5”
