Sorry about that guys. Didn’t notice someone had quoted my post.
Failure rate? My sample size is small. I’ve had 3 SLR SENTRY 7’s. One failed. I’ve had one Wilson Combat GB, this was before they started selling or partnering with SLR. It failed also. On the S7 there was no positive click on the adjustment screw. Furthermore I could not get enough gas flow to get my bolt to lock back on empty mag, additionally I could turn the adjustment screw with my finger. I contacted Todd at SLR and he had a brand new gas block with a return label in the mail the next morning before I even had the bad one pulled off. That wasn’t the first time I had interacted with Todd or Chase and their customer service in my experience, is outstanding. I can’t say enough about how they have taken great care of me in past 3-4 years. The new one functioned as advertised and I was able to tune my 308 to operate as it’s supposed to. On the Wilson Combat, the mechanism inside the gas block that closes and opens the port in the GB (I’m assuming) failed to adjust the gas flow to the closed position. I could turn set screw and it would not close. The good part of this was that it was stuck full open so my rifles would function as with a non-adjustable GB. Aside from a design that left a little to be desired (the Wilson Combat) they both did what hey were supposed to do until they stopped doing what they were supposed to do. I’ve had interactions with Dave Wilson (not sure if related to Bill or what, but a nice guy.)and Randall Robinson at Wilson Combat and they are just stand up guys imo.
The S7 clicked one day, the next it didn’t. Can’t explain it, but that’s how it happened. I never got the Wilson closed. It’s a tricky one though due to design, but I know how to adjust it.
So those are my experiences. I can’t say that it was these two experiences alone that changed my mind about using them on my weapons, because I continued to use an S7 on both my 308 and an 11.5” DD SBR and they functioned flawlessly. But at some point while discussing this with a buddy of mine, I came to the conclusion that an adjustable gb was a part that I did not have to have. Sure I enjoyed the tuning benefits, but it definitely fell into a nice to have which I measured against the must have requirement of reliability.
