I bought this to help with the hard hammering of my buffer hitting my bcg in my 10.5in AR pistol. And this really helped in my recoil softness. So this is a must to help you all if you have to soften your bcg. Plus wanted to blacken out my whole build. And this is perfect fit and finish also. So thank you cobra tac for the perfect fit to my pistol and the price.!!!!!

this works very well i love the dwell it gives me . i was hating the violent action of my pistol but this along with a heavy buffer really smoothed out my action! great finish with the black nitride. i finally got rid of the 1 shiny silver item on my all black AR

I was kind of hesitant to buy this product was thinking it was a gimic.. I WAS WRONG! this smoothed my pistol down quite a bit i also paired it with a heavy buffer and now it recoils like a 22! excellent product, pricing and finish is top notch!
