I have a mod 1 BCM comp in 1/2x28 for sale. It came off a BCM Jack carbine. It has 500-700 rounds through it. It was unpinned. Clean unpinning and fully installs on a barrel unobstructed. Throw a dab of paint or sharpie on bottom if you don’t want to see the pin hole. These go for 95 on BCMs site.
$38 shipped SOLD!! . PayPal or USPS MO. This is 100 percent functional. Will include the crush washer from the rifle also.
Thanks,
