Jmspec Posted September 7, 2022 Report Share Posted September 7, 2022 (edited) We finally finished welding up our M53 build and fitting all the parts in it. With the recuperator installed, and after bringing the bolt back (FA), the barrel does not want to come loose and the door doesnt not want to come open. Any ideas what I need to look at adjusting?

BillyDixon Posted September 7, 2022 Report Share Posted September 7, 2022 perhaps when you welded the parts together something was incorrect on over all length, orthe welding caused shrinkage,,,did you weld together with barrel in and door closed or did you install parts and now cant get barrel out ? just wondering Link to comment Share on other sites More sharing options...
Jmspec Posted September 7, 2022 Author Report Share Posted September 7, 2022 The barrel can be installed and door closed. It can then be opened and removed, but after cycling the action the barrel locks in place (bolt to the rear). Link to comment Share on other sites More sharing options...

BRMCII Posted September 7, 2022 Report Share Posted September 7, 2022 Is the barrel going back fully into battery after the bolt is cocked? Link to comment Share on other sites More sharing options...
Jmspec Posted September 7, 2022 Author Report Share Posted September 7, 2022 I just looked at it again. The recuperator is not pushing the barrel back into lock. It and the bolt are going back and the bolt is sending it forward again. Link to comment Share on other sites More sharing options...
Jmspec Posted September 8, 2022 Author Report Share Posted September 8, 2022 Well, its always slightly embarrassing when you wind up answering your own question. It turns out that the recuperator was catching on a bad spot when the bolt was pulled to the rear keeping it from return the barrel forward. Cleaned it up and it cycles now.

Countryboy77 Posted September 11, 2022 Report Share Posted September 11, 2022 Check recouperator springs, ..they are the life of the gun.Get it rebuilt with new springs and get an extra.MG42.US and weaponsguild are good sites for working out 42 quirks.
