Ordered the SBA3 brace and a Ballistic Advantage 8.5" barrel. Now looking for a handguard and I'll have almost all my parts. Then of course, try to find ammo- DOH!
Handguard might be tough. Almost all of the top tier manufacturers are out of stock. Make sure you put yourself on the notify list, if you see something you like that's out of stock.
Ammo.. well..
