This 9mm carbine buffer for use in only AR9 carbines. Perfect for your AR9 build to get her running smoothly. Best when paired with our extra heavy power (RED) Spingco buffer Springs.
EXTENDED LENGTH FOR PROPER BOLT CATCH OVERTRAVEL
Please Note – from our personal testing with our New Frontier Armory AR9 sets, This buffer will work and cycle perfectly if paired with a red sprinco extra power spring. This buffer does have enough weight to close the bolt on a new mag and successfully chamber a new round if paired with sprinco Extra Heavy Red Carbine Spring.
