Before I built the first AR in 7.62 x 39...all one could find on the subject of building AR's in the chambeiring was problems...and more problems with cycling/feeding issues with this particular chambering. The only problem I had with Spinta's barrels wasn't th barrel...it was that the system needed a enhanced firing pin for those hard Russian primers used on/in the 7.62 x 39 ammo. Boxer primed American primers you do not need the enhanced firing pin.
I am absolutely at high level of confidence on the reliability of Spinta's 7.62 x 39 since I now have built four AR with these barrels and chambering.....no jams or feeding issues and no ejection or headspace problems. In other words...Spinta has it down right with this barrel and I will not look anywhere else for a 7.62 x 39 AR barrel.
Well....since I have four other Spinta barrels and one on the way to make my ninth....I cannot see any reason to look elsewhere!! Spinta ships fast too!!!
Oh yeah...I'm a happy dude no having to fight function issues!!

I was a bit skeptical due to lack of reviews at the time of purchase. I finally tested out yesterday and 300 rounds of mixed russian commercial ammo went down the barrel without a single failure. Shot 1.5 inch group at 25 yards with just an iron sight. These guys are legit.

Ar15 barrel assembly went very well. No problems at all. Since is a 7.62x39 shooting Tula ammo, I took extra time making sure the chamber area was extra clean. Took it to the range for brake in and sight in. Ran three rounds thru for function, no problems. Ran another thirty or so rounds sighting in and general shooting went well. Have not been back to the range to check for accuracy and repeatability. I am quite happy with the performance of this barrel.

Second one of these barrels I have tried with zero feed issues. They seem to have the 7.62 figured out!!
