Description

Bear Creek Arsenal offers a large variety of AR-15 parts, so you can build the perfect rifle or pistol.

This barrel is machined from 416R stainless steel and is chambered in 5.56 NATO. This 10.5” barrel has a carbine length gas system to reliably cycle the action even with the shorter dwell time.

Choosing the right AR-15 barrel for your build is highly dependent on what you want to use it for. If you want an extremely compact AR for the range or even home defense, then a short barrel is the way to go. However, if you choose a barrel under 16” then it can only be attached to an AR pistol lower without a stock unless you file for an SBR tax stamp. Know your local laws and regulations regarding NFA items before making a purchase. Whatever you decide on building, this short barrel from Bear Creek Arsenal will make a great AR to add to your growing collection.
