Question regarding BCG

[akjunkie]

Hoping I get a quicker response here.

Recently purchased a new BCG.

Stripped and cleaned. During reassembly I experienced some difficulty reinstalling Cam Pin. I noticed the Bolt hole wouldnt line up because it went in to "deep". Had to "back out" the Bolt just a hair (about .2mm) for the Cam Pin to line up with the hole.

I was able to reassemble the BCG without any further problems.

My question is. Since i had to "back out" the Bolt there is a small (.2mm) gap between the Bolt Tail and where it is suppose to "sit" inside the Carrier.

Does this affect performance/reliability? Does the Bolt need to make a proper "seal" in the bottom of the Carrier for proper gas pressures, etc?

The gas rings seal the bolt to the carrier

The cam pin is designed to go in one way... you may have had it turned the wrong way.

Nope. Had to back out the Bolt to install Cam Pin.

If you push the bolt until it stops the pin won't go in. All BCG's are like this. Nothing to worry about, have fun!!

Normal.

Really? I got 2 other BCGs from Bushmaster and DPMS where I dont have to back out the Bolt to drop the Cam Pin in.

OK, i'll use my new BCG next time I hit Angeles. Break it in with couple hundred rounds and see what happens.

I've backed out the bolt on tens of thousands of M16's and M4's.

Normal.

OK, thanks for everyone's input.

Consensus = Normal.
