This video features Brownells Gun Tech Keith Ford and Mike Mihalski, founder of Sons of Liberty Gun Works (SOLGW), showcasing a limited-edition SOLGW / Geissele 13.7" AR-15 complete upper receiver. The build includes a SOLGW 13.7" barrel, BCG, gas block, gas tube, Radian charging handle, a NOX muzzle device, and a Geissele Super Duty upper receiver with a 13" MK8 M-LOK rail. The discussion highlights the advantage of the 13.7" barrel length, which, when combined with a muzzle device, meets the 16" NFA minimum without requiring an SBR registration. The combination promises a soft-shooting, compact, and maneuverable rifle. The description emphasizes the "one-time production run" and limited availability.
This video details the installation of a Geissele MK8 Super Modular Rail on an AR-15. Key steps include using a Geissele Reaction Rod for upper receiver stability, proper torquing of the proprietary barrel nut, and secure installation of the gas block and tube. The rail is then slid on and secured with two cross-bolts using a T-handle hex wrench. Final steps involve muzzle device installation and a thorough inspection.
