Can you polish this bolt? I'm getting a short stroke and will not cycle my rounds. Most jam or do not eject. I'm going to polish my trigger as well. Just built the gun and would not fire correctly.
Jason M on Dec 16, 2018
BEST ANSWER: I would never polish a bolt, as the nitriding is very hard and very thin. I would also not polish a trigger unless you know what you are doing, there are too many good triggers on the market. I would check the magazine first, then the ammo and finally I would swap out the bolt with another to see if your gas system is the problem. Check that your gas block is correctly aligned with the gas port.

Ronald H on Jul 19, 2018

Bolt Carrier from PSA!
I have gotten nothing but quality parts & Build kits from Palmetto! all of my AR Builds are Palmetto State & I now have 8 PSA Builds 3 PSA kits in storage for later builds & I own 4 other AR's like 2 Ruger AR 556 & a S&W MP 15 & a ATI Omni Maxx & my PSA AR's are just as good if not better than my Rugers & S&W MP 15 & the ATI is just a low budget AR I bought just to see how it does compared to my other AR's!

Gas key not staked properly, otherwise seems nicely finished.
The gas key is not staked properly. Took me about 15 seconds to notice it after I pulled it from the tube.

My unit is qualifying the rest of the week. It ought have 3k rounds on it by Sunday. See how it holds up to f/a use.
