So I took a closer look at the premium BCG a few of us got from the sale and noticed that the bolt is not moving so freely in the carrier.  It seems like the gas rings are binding along the chrome-lined interior.

 

Are any of you guys noticing this?  On my other BCG's I can move the bolt in and out very smoothly, but this PSA bolt required a lot of force to get out and is a pain to get it back.

 

Would this smooth itself out as it's being fired in my upper?  I'm worried this will cause problems down the road

BCGs run best wet.  She'll loosen up.  Only time to worry about rings is when you stand the BCG up on the bolt end and she slides into the carrier unassisted. Then you replace the rings.

Good to know - thanks TBill

 

Will have to give it a try with some m193 down the pip and hope it loosens up

Mines tight as well. I figured it would loosen up. I'm not worried

 

this signature exceeds the 15 character capacity count

PSA sends their bolts dry.  Lube it up and let it rip.

mine came tight as a gnats you know what..lubed it ..took it to CJ and ran 120 rds through it..ran like a peach

Tight is good. It means the gas rings are making good contact with the carrier and creating a good seal.

 

When they are too loose is when you run into problems.

 

The test T Bill describes above is how you check for bad gas rings and should be performed every time you remove the BCG from the rifle for cleaning it a wipe down.

 

Lube it and shoot it. You most likely are good to go.

I need to check my other BCG's now haha. One definitely might need new rings

 

Appreciate the feedback guys
