Really cool design. tight tolerance. good stuff. - Strike Industries Collar Adjustable AR Platform Gas Block

So for whatever reason, I think cause a few negative reviews when it was released, there isn't tons of reviews on this. Even though obviously a great design in theory. For me. All gas holes lined up dimensionally with my port and shoulder and were appropriately restricting on each setting. Detent and spring strong enough I have no fear it will change without intention. Tight tolerance to barrel.( Kak value line x39). I can change setting with bullet tip, lil piece of wood, whatever and I have full clock keymod only slots. Not open vents at 11 and 1 o'clock.. So, it's easy to adjust. I have a lil concern about clamp on in general and the only thing I can see possibly being and issue later is gas blow by since it is 2 piece design. However, checked after 100 rounds and no blow by to speak of . Very quality machining, and the two parts seem to mate up just perfect, tiny bit of freedom to twist the collar but zero wobble or play between the three touching parts. great idea to avoid adjustment screws freezing up. Figure even after you find a setting to stay on just twist it every once in awhile to keep free. Used a lil green lock tight since I dunno about clamp ons really. Also, definitely easy enough to customize the port sizes and can even add one more to the off position. Then for suppressed just turn to "off" and you know you are there. Overall impressive machining and finish. Great design so far. Functioned fine for 100 rounds. Still on strong and tight afterwards. Again, plenty people swear by em but I've always went set screw type with good dimples and even pinning afterward on rifle I would happily take to the boog. Time will tell on that but green lock tight works great at holding things like this on.... Took a lil risk buying it just to see for myself what it looks like. Glad I did.
