HELPING THE OTHERS REALIZE THE ADVANTAGES OF COLT 6940 BARREL WRENCH

TFB is able to acquire some photos with the upper in private hands, from the owner who bought it at a new gun present.Nicely, you can find two variants in the 6940P, and also the a person I had, I'm %99 positive the rings over the piston were similar to the rings within the bolt. I indicate I may be wrong, but IIRC mine was the later on/2nd variant
