Agree with IWC light mount being the best option. I have a Briley hand guard on one of my Benelli’s. It is really simple to remove and install (slide it over mag tube, then slide barrel through top of hand guard, attach barrel nut - no tools needed to install or remove). It is also tight and does not rotate. It really is a great design. The only things mounted on mine are a stage saver, QD sling mount, and offset light. The hand guard is wide and accessories don’t interfere with the ARGO system. It might be the best forend on the market for the M4. Problem is - it weighs almost 10 oz without accessories! It makes the gun very front heavy. I have a factory 7 rd steel mag, was thinking of trying Briley’s carbon fiber tube, but not sure if that will make much difference. My other Benelli (go to) has the IWC mount with Surefire 300c light. I also have 200 shells through that gun since mounting the IWC - no loosening at all with blue loctite. This really seems to be the way to go!
