06-530rr Posted February 13, 2014 Share Posted February 13, 2014 I think anyway. Lol still need to test the theory this weekend. I have a m2 and talked my buddy into getting a brand new SBE II limited edition. My m2 cycles anything, however so I gave found out the SBE II won't cycle anything lighter than a 1 1/8oz load in 2 3/4. So looking at them I have determined the hammer spring is the gremlin. Looking at the parts breakdown and both guns, we are gonna swap hammer springs. I believe the tension on the SBE II is just a tad too much and when the bolt cycles it can't quite compress the spring. If it does work then by simply swapping out the hammer spring for a m2 hammer spring will allow the SBE II to truly be the badass on the benelli lineup.

06-530rr Posted February 13, 2014 Author Share Posted February 13, 2014 I forgot to add, my first thought was the bokt assembly in the SBE was heave tier and that was the reason. So I stripped them both down and busted out the triple beam scale. Believe it or not the m2 bolt assembly is 6 grams heavier. Quote Link to comment Share on other sites More sharing options...
Benelligunny Posted February 15, 2014 Share Posted February 15, 2014 Hate to bust your bubble but the hammer springs are the same on everything except the 20ga guns. The fact is that the 3 1/2" stroke is longer than the 3" stroke of the M2 and it has a heavier recoil spring to be able to cycle a 3 1/2" shell into the chamber. All you're going to do by lightening the springs is to risk ammo beating up a good "heavy sporting" gun. Quote Link to comment Share on other sites More sharing options...
06-530rr Posted February 19, 2014 Author Share Posted February 19, 2014 According to the parts breakdown the hammer springs are different. Quote Link to comment Share on other sites More sharing options...
Benelligunny Posted February 20, 2014 Share Posted February 20, 2014 With different manuals come differing part numbers. If you call CS and have them look up the part numbers they will tell you they are the same. You can also look in Brownell's factory parts catalog.
