Figured I'd start here as this is where the AR guys hang out.
Testing the waters on selling my AR Performance 16" 5R 11 twist SOCOM barrel. I believe it's the SOCOM and not the Scout. I'll have to double check. Round count is between 300-400 I would guess. Shoots well but I want to try an 18" 3R barrel. I can sell the barrel for $160 shipped or include an ARP Superbolt for $220 shipped. I can also throw in my SLR adjustable gas block and ARP twisted flash hider for a total of $320 shipped. So, you have options.
I'll probably be selling my ALG Defense handguard as well but am just not sure yet.

USPS money orders and checks accepted.

PM with questions.

Here's a link to the gas block: I have it listed in the classifieds as well.
