  1. Is there any saving the BCG? Can I sand it down?
  2. Super pissed because that JP Spring wasn't cheap and I hope it isn't ruined now due to the wear and now I need to buy a new BCG.
  3. I have replaced about every part in my American Tactical MillSport rifle at this point besides the BCG, gas black and barrel and wouldn't you know it not only did my gas block have issues (I made another thread about my set screws fallout out) but now today I discovered another issue and wouldn't you know it, it's with the BCG. So I have gone through 2 buffer and I ordered the JP Silent Capture spring. Both buffers and now the JP Silent Capture spring have been experiencing heavy surface scratches/wear. I originally thought it was the retainer pin so I removed it and STILL surface scratches. so I figured it HAD to be the BCG and sure enough look what I found. BCG that came with the ATI MillSport rifle: Brand new JP Rifle Silent Capture Spring after about 60 rounds and 20 dry racks.

    Gas block pin damage?

    Thanks man you guys have been very helpful. I will continue to run it and if the set screws come out I will try Rocksett and if they come out again I will just get a new block.

    Gas block pin damage?

    Out of curiosity what is worse case scenario? Say I am shooting one day and the gas block rotates blocking the hole. What am I looking at damage-wise? Am I basically just going to need a new gas block or do I risk destroying my entire barrel or worse?

    Gas block pin damage?

    I assume military issue AR's do not use low profile gas blocks?

    Gas block pin damage?

    Would low profile gas blocks be considered a weak point of the AR platform?

    I wish I had known to use rocksett instead I put a ton of blue loctite around the set screws and it has since dried and those screws are really in there. Maybe I should fire it and then attempt to loosen the screws and apply some rocksett?

    Would staking guarantee the set screws never back out again?

    Gas block pin damage?

    What about staking the holes? I am worried about that because I will never be able to get the gas block off again right? I would hate to stake the holes only to discover the gas black has shifted.

    I am not sure of the block moved truthfully. It fired fine, the only thing I noticed was 1 set screw had fallen out (luckily it was still inside the handguard) and the other set screw was loose.

    What would cause the set screws to back out like that? The dude said they use thread locker at factory. I re-tightened them back down hard and used a good amount of blue loctite.

    It is an American Tactical (ATI) upper. I just contacted their customer support and he said they use tapered pins and the metal shaving stuff could be from when they milled the hole out.

    Gas block pin damage?

    Or is it possible that the pin was just never centered properly from the factory or has slide over to one side more because I was firing with loose set screws? There does appear to be some weird damage around the hole the pin sits in. I am starting to think my only solution may be: - Remove hand guard - Remove 2 set screws - Take a punch and hammer and re-align the pin - Reinstall the set screws with loctite again - Reinstall hand guard - Pray Do you thinking running the gun with the pin offset like that could cause any damage? The damage around the pin hole has me worried. EDIT 2: So. I saw online that apparently the pin and holes are tapered like a cone? So one side of the pin is wider than the other? Is it meant to be sticking out further on one side because the pin was "wedged" in there by the manufacturer? What would be causing that damage around the pin hole where the pin is more flush?
