edon Posted July 1, 2008 Share Posted July 1, 2008 About a year ago, SergeantBernie had a M4 barrel cut down (http://www.benelliusa.com/forum/showthread.php?t=13647). Does anyone know how it turned out? I was hoping for an "after use" update but never did see one. Was there any problems due to the barrel being about 2mm smaller diameter where the front sight & barrel lug were re-attached? Quote Link to comment Share on other sites More sharing options...
HOGWILD Posted July 1, 2008 Share Posted July 1, 2008 maybe he is deployed? PM him and see if he is still available? Quote Link to comment Share on other sites More sharing options...
warped Posted July 30, 2008 Share Posted July 30, 2008 There is more to it than just cutting it down, there is reattaching the FSB, and MTH, as well as shimming, and refinishing. See my post about SBS/BBL work It is not something a novice can do, a class III dealer/smith screwed up one guys shotgun so bad it was almost worthless. It was harder to fix it for me, than it would have been for me to do it right the first time. I spent alot of time, and money to make up the tooling necessary to do this work right.

warped Posted July 30, 2008 Share Posted July 30, 2008 sorry about the pics, but I am a firearms guy, not a photographer. In the pictures you can see that the FSB and the MTH are shimmed, and the refinishing job. Quote Link to comment Share on other sites More sharing options...

edon Posted July 31, 2008 Author Share Posted July 31, 2008 Wow, awesome work! I thought there needed to be something done about the barrel being a smaller diameter. So I guess that there is no problem with these shortened barrels with reguards to cycling and such? Are you the gunsmith that did the barrel in my original post?

Mr. Shotgun Posted July 31, 2008 Share Posted July 31, 2008 How many 2.75" shells can fit in there?? Quote Link to comment Share on other sites More sharing options...
johnnywitt Posted August 4, 2008 Share Posted August 4, 2008 How many 2.75" shells can fit in there?? Same as when it came from the factory BEFORE you put the +2 ext, or the full length tube in,which is 5+1+1 (carrier load). How much for the cut down after the Form I approval from our friends at the BATFE? Quote Link to comment Share on other sites More sharing options...
SergeantBernie Posted August 5, 2008 Share Posted August 5, 2008 I'm still around - just been busy with a new son for the past 6 months or so. The front sight and hanger must be shimmed, around 0.040" each if I recall correctly. Requires 2 different temp solders to do right I've been told. I've put about 200-300 rounds through the modded 14" bbl. No stoppages or issues at all. I've shot both high and low brass stuff and it digests it all. My brother has been in contact with a guy off AR15.com that has a fixture made for the M4 barrel shortening mod - this may indeed be the user WARPED posting here. His pics shown here certainly look like he does top notch stuff. The pattern has opened up, but it is still a lethal close to medium range skeet gun. With 6 rounds semi-auto, whoever is running the auto skeet thrower can't throw clays fast enough to overwhelm you. I love the 14" M4, but have also been thinking about getting a spare 18.5" bbl to get a little extra range on skeet. Then again, I try to pick a use for a weapon and stick with it so I don't have hundreds of dollars of parts/optics accessories lying around unused (or God forbid - connected to the weapon) like some sort of mall ninja. The M4 SBS with a side saddle is awesome the way it is. Quote Link to comment Share on other sites More sharing options...

warped Posted August 18, 2008 Share Posted August 18, 2008 $200.00 plus shipping, if materials keep going up in cost (silver, acetylene, O2 etc. I may have to raise prices by $20) Quote Link to comment Share on other sites More sharing options...
