Benelli M4 stock extension removal - any shops offer this service?

Recommended Posts

I just picked up a Benelli M4 that has the factory collapsible stock that only functions in the fully open position. I purchased the correct/complete 3 position factory tube assembly and am all set to install it (and all the appropriate 922 compliant parts as well) but I'm having a heck of a time getting the factory nut on the receiver extension tube to come off. I doesn't want to budge.  I researched this forum and found that it is set with green/red locktite, looks to be out of the scope of the tools I have on hand to get it off.

Are there any shops/forum members that offer this as a service? I appreciate your time, thanks for a great forum!

The buffer receiver extension has green loctite and a locking nut on it as well which is also loctited, I had heat on that for longer than 30 minutes and then it finally budged.  Just be patient or you'll risk stripping your $1800 shotgun..

Thanks Chile1, not sure my nerves would stand up to 30 minutes with a heat gun on a shotgun this expensive! I plan on sending it to StrangerDanger. Thanks y'all!

Thanks for the recommendation. Using a heat gun takes forever and sometimes doesn’t work. A MAPP torch will break down the thread locker in a few minutes. It has a nice controllable flame to keep the heat off the receiver and in the old receiver extension mainly.

Quick follow up to my original post. I sent my receiver to SD and he had it repaired literally within a matter of hours of receiving it and boxed and shipped back to me the next day. The communication, workmanship and customer service were all beyond superb. SD obviously takes a lot of pride in his work and it shows. He is a wealth of knowledge on the M4 platform and we are lucky to have him as a forum member. Thanks again SD for everything!

Glad I could help. I know when I came across this problem back around 2010, there were zero options available to get this fixed. Benelli would tell you that you’d destroy the receiver attempting to change these extensions out.
