I replaced most of my AR rifles with the SLR and Syrac gas blocks . I just received my SLR Sentry gas block for my latest build and it looks like the best one yet. The adjustable gas blocks are the reason I dumped my gas pistons and can recommend them without hesitation, top quality all around. I'm glad to hear your SLR gas block works as well as mine have.
