- I am no expert in this area. I am also not a machinist or
- gunsmith. But, I do have a U.S. Marine Corps Technical Manual
- (TM 05538c-23&P/2), "Organizational and Intermediate Maintenance
- (Including Repair Parts and Special Tools List)".
-
- There is a chapter "Intermediate Maintenace Instructions". On
- Page 3-56 in my manual it discusses the lower receiver - just the case
- not the guts. Amazingly, it explains how to fill corrosion pits. It
- says that corrosion through the receiver is non repairable. The pivot
- pin lugs seem to be the Achilles heal. If they are corroded or widened,
- the lower receiver is junk.
-
- Also the hammer pin holes and trigger pin holes can become
- enlarged also making the unit unserviceable.
-
- There seems to be no discussion on breakage or wear of the
- internal moving parts. But I suppose they are self evident and not
- something that needs special checking.
-
- This manual is available from Lone Star Ordinance (800)
- 482-3733 or (512) 681-9280. Order Number 56TMA223P2 $13.95 Visa,
- Master Charge etc OK.
