If you’ve been looking for a Light Weight BCG you are probably very aware that they can be very expensive. Especially when you start looking at special coatings like Nickel Boron, etc. AIM Surplus just released a great looking Light Weight Nickel Boron BCG that totally breaks the rules by coming in at just 8.5 ounces (almost 28% lighter than their standard BCG) with a price tag of just $120 and Free Shipping. Light Weight BCGs are not only great for those uber light weight builds but work great for 3-Gun/Competition shooters looking to tune a gun for super light recoil and fast follow up shots.

Assembly
The requirements for assembly of our Bolt Carrier Groups are much higher than most. Before assembling the gas key to the carrier, permatex NO.3D aviation is applied to form-a-gasket around the gas hole (per MIL-SPEC). Then Grade-8 hardware is used to attach the gas key, followed by properly staking per spec. When installing the extractor to the bolt, a crane-o-ring is inserted with the spring to insure proper ejection. Then high temperature grease is applied to the gas rings before inserting the bolt into the carrier, which allows for much smoother operation. These BCGs are inspected to the highest of standards, to insure a high quality product that is 100% reliable for our customer… PROUDLY MADE IN THE USA!
