OK I have an MSG-90 Clone which started out as an HK-91 then received an Urbach barrel, rails, etc.....

When I pull back the cocking handle the Bolt assembly does not come forward unless I give the gun a severe pop the the end of the butt stock then it goes forward.

When I use a standard HK-91 stock it seems to work fine...

Any ideas on what could be wrong?

Thanks!!

GMANinGA out.

The first thing that comes to mind is to check your recoil spring to make sure it isn't binding.

Does anyone know if the recoil springs for a Std 91 are the same as a MSG90? Perhaps I can swap them out..

Kinda hard... or more difficult than the HK-91 factory stock.... I also have a PSG-1 stock on my SR9TC. I will try that one when I get home tonight.... I did not even think of it as it is in another safe.....:) too many safes.....
