I just got my SBR and now have decided to get a can for it and my other black rifles. Any suggestions? I want a good one but surefires are a tad expensive, has anyone seen or used a OPS INC can? They are built to military specs and seem like a logical choice. I want QD and the Gemtech's are the shizzel for that. Weight and noise are the next considerations as well as warranty. Come on some one has good intel and can hook me up.
