Almost an ultimak killer - Troy BattleRail AK47 Top Black SRAIAK1T0BT00

This gas tube works just fine but there are a few things that keep it from be perfect. If you tighten it up too tight it has a drastic effect on group size and POI/POA. I have a Home built rifle that does 1 MOA at 100 yards with Lapua ammo using an optic sight attached to the side rail of the receiver. I installed the M-LOK Battle Rail with no changes in accuracy but when i installed the gas tube and tightened it up my 100 yard accuracy went into the toilet. I loosened the gas tube to where it just made contact with the sight block and the gas block and my accuracy came back but i could not keep the gas tube secured on the weapon as the securing nut kept loosening as it became hot. I tried red Loctite to hold it in place but the tube gets hot enough to defeat red LT. I ended up drilling the nut and placing 2 Allen screws in it so i could lock the nut in place without having to over tighten it. Now i can remove the gas tube for cleaning and i have My 1 MOA back. I would suggest this modification to Troy to truely make this fully adjustable unit the Ultimak Killer. I like the idea of making one that fits all and it is a quality made accessory for sure. I gave it 4 stars because of this. It is also a good idea to install the inserts in the top rail as it does get blistering hot during long strigs of fire just like the original. A great idea, very high quality, very well done except for the one thing i mentioned above. I would buy it again, the modification to make it perfect is not hard to do and only takes a few minutes.
