If you don't have one, before changing out that barrel or installing a new barrel, get one. It takes all the pressure off of the notch and barrel pin, it lines up the barrel to accept the bolt lugs and it does not stress the receiver as other rods without the top sail will do. For building AR's or changing out barrels this is a must have item.

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

This is another high quality product from Troy. It fits well and is easy to install. It allows for a longer grip area and greatly improves the looks of the AK rifle. Be sure to order the M-Lok rubber inserts and a vertical grip as the rail gets extrememly hot on long strings of fire. The inserts will allow you to maintain the longer grip when the rail gets warm, after it gets really hot you will want the the vertical grip if you are not wearing gloves. I tested this rail to make sure it did not effect the accuracy of my rifle since it bolts onto the barrel. It did not change the group size or the POI at 100 yards. The matching gas tube will effect this if not properly installed but that is another review.
I would buy this product again and would highly recommend it to anyone wanting to modernize their AK rifle.
