Use this on my suppressed SBR. Can't say enough about the ease of installation and adjustment. Very smooth, solid clicks. Syrac was backordered for ever, so a friend recommended SLR. No regrets...I'm impressed and will be using them on future builds!

Fits under my BCM KMR with plenty of clearance for attachments around the block. The machining and finish is spectacular. It's all in the details and SLR crafted a superior product to ANY OTHER on the market. I ordered a adjustable GB from JP ent. but it just wouldn't work with my KMR and thank God it didn't because SLR's gas block it in a class all by itself . I live on the west coast and ordered the block on a Tuesday and it was on my barrel on Thursday! That's customer service. The settings are solid compared the the previous block I mentioned and I don't see anyway they will move unless you make them. Just can't get over the excitement I have for this block. No worries on reliability here. Get one!
The best adjustable gas block on the market hands down.
We are using these on all our custom builds where people will be running silencers. They are easy to adjust and work great.
