The Comments Section Carbine Giveaway
In October, we decided to do something special. Throughout the month of September, we let you guys build a firearm in our YouTube shorts by tallying up your build decision votes and letting you guys drive the gun bench. Then, we partnered with our friends at Griffin Armament to upgrade your build even more.
AT3 upper and lower in Tungsten Cerakote, Ballistic Advantage 12.5″ 5.56 barrel, STNGR BCG, SB Tactical SBA5 brace, and the Griffin Armament HUB Dual Lok 5 AM Suppressor. Sig Romeo5 Gen II up top with a Juliet3 magnifier, an Inforce WML for the top rail, and a BCM MCMR 10 handguard.

You Guys Built It, Now You Might Win It
(October 1-31)
We gave you guys every option in our warehouse to build whatever rifle you wanted, and this is what came off of the gun bench.
A titanium AT3 billet upper and AT-15 lower anchor the build. A Ballistic Advantage Modern Series barrel sits under a BCM MCMR handguard. A Superlative Arms adjustable gas block, STNGR chrome-lined BCG, and Radian Raptor SD handle keep it running clean with a can. More on this in a second.
A Rise Armament lower parts kit and Rev 535 trigger deliver a crisp 3.5-pound break. An SBA5X brace and Magpul MOE SL grip handle the ergonomics. A SIG ROMEO-MSR and JULIET5, Inforce WML, and Magpul MS1 sling finish the package.
To top it off, we partnered with Griffin Armament to add in a HUB Dual Lok 5 AM Suppressor to fully finish this build. The winner will receive a gift certificate from Griffin Armament good for the value of one Suppressor.
Total Package Value $2949
