Lower Assembly Problem

[Hawkstp]

This is my 3rd lower, so I am not a complete newb, but not a master gunsmith either.

Everything was going easy till I went to install the pistol grip and selector.

Installed the selector, dropped in the selector detent, round in first. Installed spring in the pistol grip, screwed on the pistol grip watching for spring to go in fine.

When I went to function test the selector, and yes the hammer was cocked. The selector will go from safe to fire, but it will not go back to safe again. Seems like to much pressure from the detent, but that does not make a lot of sense to me. Again the hammer is back.

Any help would be great,

Thanks Gary

ive noticed that the selector can be super hard for a bit on some kits, such as cmmg. as long as the detent is pointing the right way, i usually just muscle it back and forth. it works after a couple cycles, at least on my builds it has....

I put a dab of grease on the selector detent to smooth things along a bit. Any time you have a shaft reciprocating a hole like that, you want to grease it.

Is it hard to move from safe to fire? also do the grooves on the selector look about right?

I have never really checked out the grooves that closely on my other builds, so can't say if the look about right.

I will try to grease it up and just try to force it pretty hard and see if I can get it to loosen up.

again, giggity.


really though, hope you get your problem figured out. i almost needed a hammer to get my selector to move on two of my builds...

[Hawkstp]

Well thanks for the help guys, lubed it up a bit, and forced the hell out of it. She worked!

Often, the phosphate finish will settle into the grooves, making them way out of spec and certainly not slick. The phos will get worn down quickly with use, quicker when you grease the groove too.
