About
our company

Custom Build Engineering (CBE) is the collective vision of five shooting enthusiasts to produce an accurate, durable and higher performing carbine based on the legendary AR-15 platform.

Thoughtful research and sourcing of better performing components brings together the CBE vision of durability, accuracy and performance at an attractive price.

Delivering on the founder’s vision with a sense of low key humility that make even quiet professionals proud.

The result is the CBE BRR-M4 Multi-caliber rifle.

Other rifles are good, we make ours better.
