Product Spotlight: SOLGW / Geissele 13.7" AR-15 Upper
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.
