Fallout 3 Posted September 19, 2016 I've done quite a bit of googling and now I'm wondering what you guys have. I'm building a new upper for my .308 and I'm in between an 18" barrel and a 20". Can you guys post up your ARs (preferably 308s) with 18" and 20" barrels. I have the option between a 12, 15, and 16.5" handguards. I'm looking to see what a 12" looks like on the 18" mostly but post what you've got and note what length everything is. Quote Share this post Link to post Share on other sites

It looks like i'm leaning more toward the 18" but i'd like to see some Quote Share this post Link to post Share on other sites
