Frequently Asked Questions

What is the advantage of a 13.9-inch barrel on an AR-15 platform?

A 13.9-inch barrel, when paired with a compatible muzzle device like a flash hider and spacer, can achieve the legal 16-inch rifle length. This offers a more compact firearm suitable for home defense or as a truck gun, without requiring NFA registration as a Short-Barreled Rifle (SBR).

What makes the American Defense Manufacturing lower receiver special for the BRN-180?

The ADM lower designed for the BRN-180 features an integrated 1913 rail at the rear, which means it cannot accept a traditional AR-15 buffer tube. This design is specific to the BRN-180 upper and allows for different stock configurations, often folding stocks.

Can you shoot a BRN-180 build with a folding stock while the stock is folded?

Yes, the BRN-180 system is designed to be functional even when the folding stock is collapsed or folded. This adds to its versatility and compact nature, making it easier to maneuver in confined spaces or transport.

What are the benefits of the Jmac Customs folding stock on this BRN-180 build?

The Jmac Customs folding stock provides a significant reduction in the overall length of the firearm when folded, enhancing its portability and concealability. It's also designed to be robust and compatible with the BRN-180's non-traditional buffer system.
