Geissele near clone M4 SOPMOD Carbine with 14.5″ URGi 

Released by Geissele in 2020, then retired, Charlie’s brings to you as a custom-built kit in 2021 / 2022

The Super Duty URG-I M4 Carbine brings you to the forefront of performance by mating the URG-I Upper (currently fielded by USASOC) with a Colt Carbine Lower. Field tested and proven, this 5.56 NATO chambered, 14.5” carbine is assembled by Potomac Armory in the USA. The Geissele SMR Mk16 brings you unparalleled M-LOK modularity and ergonomics. Potomac Armory includes the Geissele 2-stage match trigger.

Features matching set of Geissele milspec anodized black receivers – upper and lower

This rifle kit comes with some of Charlie’s favorites:  in addition to the awesome Mk16 rail, a Geissele milspec forged matched set upper and lower receiver, military grade Geissele 2-stage trigger; Geissele Maritime Bolt Catch, FN mid-length barrel and B5 SOPMOD.  We love B5.  Great products.

This is a no tax stamp 14.5″ rifle, as the flash hider is pinned and welded. 

The original carbine was a special release by Geissele in late 2020, but was a one-time build.  At that time, Geissele was featuring the Daniel Defense mid-length gas barrel and Surefire SOCOM 4-prong flash hider.  This build is considered by many to be an upgrade, as it uses the very popular Surefire SOCOM Warcomp 3-tine flash suppressor and a carbine gas system.  Both accept currently manufactured Surefire SOCOM RC2 and Mini-2 suppressors.  We realize that some collectors would like to have the Surefire SOCOM 4-prong, but it is becoming harder to source, and the Warcomp is universally agreed to be an improvement in performance.

Some options that Charlie’s recommends with this rifle:

• Surefire SOCOM mini suppressor in FDE or black (ready to attach to your flash hider)
• Nightforce NX8 1-8x scope and Geissele mount combo
• Vicker’s Blue Force Gear standard sling in Coyote Brown
• Amend2 FDE 30 round magazines

Manufacturer’s model was 08-350 before being discontinued.

Note:  some pictures reflect the original Geissele offering with the 4-prong flash hider.  That is not an option.  The Surefire Warcomp is the correct muzzle device.  Residents in states that ban flash hiders can request a Surefire brake at no additional charge, but expect additional armorer time.

Note:  some pictures reflect the original Geissele offering with the DDC charging handle. This is not an option.

Note:  This is a rifle kit.  The upper will ship to your home and the lower to your local firearms dealer.  The parts came to Potomac as an upper and lower, and will ship to you as an upper to your home and a lower to your local gun dealer.  We call this a rifle kit.  The upper is fully assembled, and the lower is fully assembled, but we are not shipping a rifle to your dealer.  You will be required to connect the upper with the lower.
