Replace the lower?
replace the trigger?
buy a new top of the line reciever set?
ffs, you guys are unbelievable.
$20 anti walk pins is the easy fix.
Shouldn't be "walking" any goddamn where in the first place.
Aftermarket and custom shit comes with aftermarket and custom problems. More aftermarket shit isn't the fix.
Quality parts also come with less issues, sometimes you get what you pay for. Not to say that Aero is junk but they do have some random fit issues I don't have with Noveske, etc.
Got to wonder what force is moving a trigger pin out of the reciver in 20 shots?
Considering the times I went to qualify in military service, and the fact that the rifles provided by the armory were without a doubt the most worn out slop buckets available to mankind.
They did in fact not fall the fuck appart during qualification.
Is there not instructions saying the trigger pin is to be inserted in a specific direction ?
Aside from that a few measurements would sort out gross error.
Right?
It's why I stand by going back to a GI trigger and working back until you find the problem.
Just a guess but I'd say it's an out of spec trigger pin that doesn't have a deep enough cut for the hammer spring to engage. But can't say without seeing it. That would be the most likely culprit. Or a weak hammer spring.
And no, the trigger pin generally has a cut on one side so the hammer spring will rest on it regardless of how it's installed.
One thing worth mentioning though now that I think of it, Geissele did sell some "special" trigger sets to Brownells some years back... These have a different retention method. It's been a while since I had one apart though so I can't say for sure that'd be the issue. It did use a special spring to retain either the hammer, trigger or both.
Again, stock GI trigger. If it works, then contact Geissele and request another pin or RMA the thing.
Almost everyone on here has a drawer full of these too. I may have given mine away already though... LPK used to ALWAYS come with 'em.
