If you are looking for the basics for an FBI HRT build, this is a great start. Charlie's has partnered with Potomac Armory to bring you a balance of the right parts and not break the bank. This is the current production Geissele 10" OD Green Federal (FBI) rail with laser etched T-marks. We have selected a Daniel Defense Cold Hammer Forged 11.5" barrel with a Troy gas block and stainless steel Remcon Defense gas tube. A Surefire 4-Prong 'fast attach' flash hider rounds out this offering.
The rail and barrel kit will fit a mil-spec upper receiver. Potomac recommends forged receivers, like Colt, LMT, Daniel Defense, Bravo Company, FN or Rock River to name a few. Billet receivers sometimes do not do as well timing to the Geissele rail.
Note: All items arrive in a box unassembled.
