Excellent quality gas tube - Troy BattleRail AK47 Top Black SRAIAK1T0BT00

I bought this for my VEPR and it fits nicely, with Troy quality and precision machining. I've put ~200rnds through since it was installed with zero issues. The tension-nut did loosen after the first few mags (as expected), but after tightening it it's been 100% functional.

I did have to do some filing to the top of the hand-guard retention ring, as it sat slightly high for the gas tube to sit level. It only took a few minutes of filing the top of the retainer, and it was ready for action. I'm guessing this was more of a VEPR 'problem', as they use slightly thicker parts for their rifles, so it could be an isolated issue.

Although it's fairly expensive, you know it's worth the price.
