Anyone here done business with Tactical Ambush? I am interested in in their 101/2 7.62x39 complete upper.
They state on their website that they only warranty problems using factory brass ammo and will not guarantee problems
using steel case or foreign ammo.

i have one of their 10.5 inch 7.62x39 barrels.  as it came from TA, it would not cycle russian steel case ammo. they apparently size their gas ports for the use of higher pressure American made ammo. they are not a fan of russian ammo., i believe.

the guys at TA were kind enough to open up the gas port for me as i only shoot russian ammo. i do live in florida, however, so i was able to deal with this fairly easily. the TA guys are good guys.  if you shoot russian, be ready to open up the port. the barrel has shot great since they did the mod.

Thanks for the info swadiver
