I recently picked up a used m40-a1 off gbroker. During my first trip to the range I had multiple issues, but we'll see if the new parts fix it.
My current question:
With a full 12rd magazine, it is difficult to rack the first round. I read a similar thread, and it ended with the gun needing breaking in. Since mine is used, I don't know if this is the case. What's unusual, is that when it does grab the first round, there are two visible lines running the partial length of the round. The 'scars' start on the bullet itself, nick the front of case and continue on an 1/8th inch or so. Occurred with several types of ammo. If the top of the mag has gotten flared, could the round be sitting high and catching on something it shouldn't?
I'm going to post pictures later, as I also have tear drop shaped primer strikes, failure to extract, fail to hold open after last round (may be mag spring issue) and slide doesn't fully return to battery under spring power alone. I've got parts coming from SAI and a new rod and bushings from BT. We'll see, and sorry for the long post. Thank you
