Hello all,
I have a question about an AR-15 it's made by Anderson Manufacturing company...
I bought this weapon from a buddy of mine for $150 dollars cause he need the money to keep his heat on...
Any help took it apart to clean it and lost the roll pin for the gas tube...
I have been trying to find out what pin group this belongs to so I can buy a set of pins and springs...also how do I install it? Any help out would much be appreciated....
Thanks in advance,
txsred66

PSA will have various spring kits available, not sure if they include that roll pin with FCG springs.
Not sure why you removed gas tube from block to clean. It’s not necessary to do so. Maybe if you have an adjustable block that’s stuck, you may need to.
Buy roll pin starter punches and roll pin punches.

Thanks so much for the birthday info I had forgotten about YouTube videos....
I don't know why he took off the gas block or the gas tube....
I hate to say this bout my friend but he ain't the sharpest knife in the drawer....
Thanks again,

Midway USA has the parts you need under "AR-15 Stoner AR-15 Ultimate Repair Kit", it'll have the gas tube roll pin and lots of repair parts for $20.00 on sale this week. I just ordered the kit to throw in my tool box with my other AR parts, couldn't pass up on that deal.

Will you will be needing a wrench for the barrel nut as well?

Funny story, I’ve built about a dozen AR’s, and none of them had the military type delta ring barrel nut that uses pins to install, until this last one. That was the hardest thing to clock for the gas tube with the proper torque, I swear I tried 4 different shims and combinations….I’m definitely a free float fan.

Why remove the gas block for cleaning? Just jam a pipe cleaner down the tube if you want to clean it but really unnecissary.

It's an 1/8" roll pin, Ace Hardware probably has them. Or any hardware store most likely. Don't count on Homer Depot or Lowes.
