Looking for adjustable gas blocks for my 308 rifles. I'd like blocks that are adjustable from the front, preferably something that has clicks or a some other locking mechanism. One will be set and not adjusted, the other will be used with and without a suppressor so it might be adjusted up and down regularly if that makes a difference.
The SLR 7 seems to fit the bill, are there any others that fit the criteria?
I was not impressed with the Syrac blocks I had.
