I cant tell you how awesome this tube is. My bushy 16" couldn't go 20 rounds without short stroking or FTEing even with 556. This solved all my problems. Installation was super easy and after about 10 min I had it installed. Very positive seal in the gas key. To test it, I ran some cheap wolf ammo that wouldn't even cycle before (serriously, would FTF every round). 300 rnds and no FTEs or FTFs with wolf and tula. The BCM tube was also slightly longer than Bushmaster factory (about 1/2 mm) which I think helped a lot. If you are having gas leaks, start with this part, and then try a BCM carrier. Both are totally worth the coin!
BCM gets 1 billion stars. I am super happy! I have a working rifle again!
Just got my gas tube, fit perfectly, actually better than perfect. it fit better than the original. after messing up the original because it was to difficult to get into the gas block i bought this one expecting the same. except i was able to insert the tube without too much struggle. great product.
Excellent part. Easy to install. Worth the money.
