Something wrong with boltcatch

[StacattoP]

So I'm having some issues with my bolt catch it's not catching the bolt or pushing the follower down on the mag and for some reason it's got a lot more space it's allowed to travel than a normal bulk catch I've tried changing out the bolt catch try changing out the spring but I'm still doing the same results as you can see in the picture the bolt catch is not supposed to be that high

maybe forgot to put the part that goes on top of the spring (I don't know the technical name)?

middle part in this photo:

Nope the spring and detent are in there this is an 80

 

[srxfan]

Wow, hm. That does seem very high... maybe the hole is out of spec, allowing the bolt catch to be pushed in so far? Or maybe the spring is going over the thicker part of the detent when you push in?

 

[StacattoP]

I've to the conclusion without tools that the hole is sadly out of spec but trying to come.up with a fix

 

[srxfan]

stuff something else in the hole to get it back up? May have to trial and error that... good luck!

Can you post another photo showing the bolt catch with and without a mag?

Looks like a good candidate for a 22 upper or similar that don't utilize the bolt catch.

Great idea

Or, if the hole is out of spec, contact the company you bought it from and see if they'll make it right.

Might not be worth the cost or gamble, but maybe a modified Armalite AR-10A catch.
L to R: M16, AR-10B, AR-10A

Yeah, that paddle should be almost vertical.
Maybe the detent pocket was bored too deep ?
I'd take it apart and check the length of spring, detent and pocket depth.

Next time you install, use a slave pin.
This does two things :
1) Gives you a way to test the assembly before committing to driving the pin.
2) Keeps everything aligned while you drive the roll pin.

Hmmmm....Here are my observations.

What do you mean by pushing the follower down on the mag? The follower should push the bolt catch up. It should move freely.

You are pushing the mag catch to max height. Are you saying if you do this with an upper on it the BCG doesn't lock back? Is the BCG traveling far enough back when you charge it?

I never assume the lower is out of spec enough to matter over some run of the mill parts kit. QC is much more likely to less on a parts kit from anyone than a lower imho.
