Rod Guide Damage


Recommended Posts

Impressions made by the rear guide rod retaining plate. Frank I. recommended replacing the M3A1 rear plate with one from an M3. This I plan on doing over the weekend.

 

Any one see any serious issues with the condition of the rear of the receiver? Or is this normal for this type.

I can't comment on your situation, since I haven't held a M3A1 in years, but it would worry me. I think you are wise to install a M3 guide rod.

I am also aware of Frank I's warning. In an attempt to prevent this from happening with my GL M3 I made a buffer by cutting 2 peices of plastic milk botttle and installing them behind the back plate next to the receiver.

Too soon to tell if it helps.

Is your gun a GL, Ithaca, or Media?

Good luck.

Worn out recoil springs and constant mag dumps is most likely the combination that lead to this.

 

Or hot reloads. That M3A1 came to me in the condition shown, at the time those photos were made I had not shot it.

 

I traded it for a 1928A1 Thompson that summer and have not regretted getting rid of it one bit.

Correct-constant diet of hot loads will wear out the springs and let the rearward motion of the bolt slam the back of the receiver. My gun sees 5,000-8,000 rds a year and every spring I put a new sear and recoil springs in it. Every other year I put in a new extractor.
