I have a Sprinfield Milspec that I've been playing with.
History:
The original problem was that the plunger tube was loose. So I bought a staking tool from Brownell's, and re-staked it.
Of course, I crushed the tube before I realized that the slot in the block of aluminum was too shallow.
So I consulted Kuhnhausen, and reamed it out with two drill bits.
Then I noticed that the slide was hitting the top of the slide lock, with no clearance, so I put a dimple in the end of the slide lock. Of course, I made too deep a dimple, and went back to the old slide lock, and put a dimple in it that was too deep, too.
Fine. A new slide lock, and a much smaller dimple.
Then I theorized that the crushed and reamed tube was making the plunger too stiff, and I once again assembled my courage, took a deep breath, and jerked the old plunger tube off, and replaced it according to the K. manual. Locktite everywhere. Locktite on my fingers, locktite in my hair, and my sandwhich tasted suspiciously like locktite.
Of course, I forgot to put the little mandrel thing in when I installed the new plunger tube, so I crushed it, too.
Plunger tube number three was installed correctly. A new plunger feels much softer than the old one felt.
It's now on the third slide lock and the third plunger tube. I take great pride in the fact that it's only on the second plunger, mainly because I haven't figured out a way to screw it up in one fell swoop.
Now, it cycles correctly by hand, and at the range, I loaded one round per magazine, and fired it, and it locked back correctly. I did that twenty times with each magazine, and it functioned perfectly each time.
Then, when I loaded each magazine full, it failed to lock back on each magazine.
Then I loaded them full again, and it locked back correctly each time.
My only hope now is that the dimple I put in the new slide lock is too deep, and I think I'll try one more new slide lock, with NO dimple, (I've now spent more on new slide locks in the last month than I spent in the same month on my wife ) and then I'm going to buy a set of bellows, build a fire, and melt the damn thing down to a puddle of slag.
Any suggestions on what else I can check?:banghead:
