Recently we reported about the Brownells lightweight AR-15 bolt carrier groups. Shortly after releasing that product, Brownells has also announced that they are now making titanium AR-15 and AR-10 bolt carrier groups. As you know, titanium is very lightweight. As a matter of fact, their standard profile titanium AR-15 BCG is even lighter than the skeletonized steel one.
AR-15 Titanium Bolt Carrier Group
Brownells titanium AR-15 bolt carrier group weighs 7.9 oz. The bolt carrier is machined from 6A1-4V titanium and the bolt is made of 9310 tool steel. The bolt is also magnetic particle inspected (MPI). All the components of the bolt carrier group feature a DLC (Diamond Like Carbon) coating. These BCGs also have an M16 profile tail which will make them fully functional with select fire lower receivers, too.
Brownells titanium AR-15 BCGs are shipped fully assembled. They are made for .223 Remington / 5.56x45mm NATO and other cartridges based on the .378 case head diameter (.204 Ruger, .300 Blackout etc.). The MSRP is $299.99 on Brownells website.
AR-10 Titanium Bolt Carrier Group
Along with the AR-15 BCG Brownells has also released a titanium-made bolt carrier groups for the AR-10 rifles (DPMS/SR25 pattern). Despite being larger than the AR-15 bolt carrier group, the AR-10 one weighs only 12 oz thanks to the lightweight material used. Most of the features of the new AR-15 and AR-10 BCGs are identical. The Brownells titanium AR-10 BCGs also have only the bolt carrier made of titanium (6A1-4V) with an MPI bolt made of 9310 steel. These AR-10 BCGs feature a DLC finish, too.
Being made for the .473 case head diameter of the .308 Winchester cartridge, this BCG should also work with a number of other cartridges with a similar bolt head (.260 Remington, 6.5mm Creedmoor, 6mm Creedmoor etc.). These AR-10 BCGs are available through the Brownells website at an MSRP of $379.99.
