Fix my gun Panzer arms m4 barrel space question.

Post image

Hi everyone,

Hope you are well. Bought a panzer arms m4 to add to an Italian collection.

Took it apart to clean it and putting it back together I see there is a thin gap between the barrel and receiver.

I can't remember if this gap was here before I took it apart.

Does anyone else have this gap? If it shouldn't be there does anyone who also has one who had the same problem have a solution for how to fix it?

Thanks for your input!

Its a turk gun. Italian gas system. The barrel has a really tight tolerance and will form better to the receiver after taking it apart a couple dozen times. Use a rubber mallet and tap the top end or what I've done is tap the gun onto the ground barrel pointed up and the barrel slides into place. Love my m4 speed pro, I've put 10,000 rounds through it with 2 issues in which neither effect the shooting.

How is yours with light target loads? Mine was working perfectly with some Winchester ammo, but recently has started acting up with some challenger ammo. I'm going to try Winchester again, but curious if yours has issues.
