the best I have seen, you won't beat the price either
this was my 1st purchase from Gorilla Machining and I am very impressed. this is my 3rd adjustable gas block, and all from different makers and this one is the best by far, bigger beefier screws so they won't strip out as easily (and probably not at all by the looks of it). The fit and finish is flawless. I have been building custom AR's for 5 years now and always looking for new products to try and now will only be buying these from Gorilla! I put this one on my 300 blackout AR pistol and it works great and looks great too, Love the QPQ coating and it's lighter than the ultra light cobra tac gas block i took off. I couldn't be happier with it and will be buying more of these and other Gorilla parts soon. Most are out of stock, so i am waiting.
My local gunsmith/ ffl sells some ar parts so i took this up to show them and they were as impressed as i was. great job Gorilla, keep up the good work
