dspd204 Posted July 10, 2006 Share Posted July 10, 2006 Has anyone installed a Weaver 93/Picatinny rail on their SuperNova. If so, what brand did you use and were the supplied mounting screws too long? Benelli customer service told me that they might be. Thanx!

Guest GunCrazyD Posted July 12, 2006 Share Posted July 12, 2006 8-40 screws are the right length Quote Link to comment Share on other sites More sharing options...
tucker301 Posted July 12, 2006 Share Posted July 12, 2006 8-40? 8-40 does not indicate a length at all, just the diameter and thread count. #8 (.164" diameter) 40 threads per inch If the screws are too long, cut them to a shorter length.

Mesa Tactical Posted July 14, 2006 Share Posted July 14, 2006 I can't help you, but I'd be really surprised if any factory threads weren't metric. Benelli M2 Tactical and M4 shotguns are factory tapped with M4 metric threads. The screw length depends on the thickness of the rail and the depth of the countersink or counterbore. With the M2 and M4, it's very critical because on the one hand there isn't much material there and you want the screw as long as possible; but in teh other, if it's even slightly too long it interferes with barrel removal. This is all for reference; we don't know much about the SuperNova. It could e very different. Quote Link to comment Share on other sites More sharing options...
