Sons Of Liberty Gun Works recently announced a limited production run of its SOLGW MK1 carbines and rifles in the historic USMC Frog Skin camouflage pattern to celebrate the 250th anniversary of the US Marine Corps. The Frog Skin pattern is reminiscent of the Pacific Theater during the Second World War, where the US Marine Corps fought across island campaigns against the armies and navies of Imperial Japan. Two shades will be available, a “beach” and a “jungle” variant.
The Sons of Libery Gun Works MK1 series are direct-gas-impingement firearms based on the AR-15. Both its upper receiver and the railed M-Lok handguard are designed to mesh together at the rifle’s breech area to mimic the continuity of a monolithic rail in order to offer the end user a “seamless” rail space. This makes it easier to mount optics or gear that work directly with each other, such as magnifiers and red-dot sights or thermal sights and/or IR laser modules. The top portion of this continuous stretch of rail space also includes a deep-cut channel through the middle of the Picatinny rail surface to aid the user with cable management and routing for any tactical accessories mounted around this SBR.
The edges of the Picatinny rail surfaces are also scalloped and rounded in order to reduce sharp edges that could potentially be harmful to the various cables from the end user’s gear. Sons Of Liberty offers three different kinds of barrels, from stainless steel to standard CMV barrel steel to a polygonal-rifled barrel. The gas ports in these respective barrels are conservatively sized to provide smoother function with suppressors.
All Sons of Liberty Gun Works Mk1 SBR lowers are built with longer-A5 length receiver extensions. These elongated buffer tubes use a rifle-length recoil spring and a longer, heavier buffer to provide smoother and less violent and abrupt cycling for a more consistent and predictable recoil impulse.

As someone who’s interested in tactical accessories, I appreciate the emphasis on seamless rail space and cable management in the MK1 series, it’s a big plus for me.
I’m skeptical about the claim that the gas ports in the barrels are conservatively sized to provide smoother function with suppressors, can anyone confirm if this is actually the case?
From what I’ve read, the gas ports are indeed designed to work well with suppressors, but it’s always best to test it out yourself.
The use of longer-A5 length receiver extensions and rifle-length recoil spring in the MK1 SBR lowers is an interesting choice, I’d like to know more about how this affects the overall performance of the rifle.
The fact that Sons of Liberty Gun Works offers three different kinds of barrels, including stainless steel, standard CMV barrel steel, and polygonal-rifled barrel, shows their commitment to providing options for their customers, I wonder which one would be the best for suppressor use.
The attention to detail in the design of the Picatinny rail surface, with a deep-cut channel for cable management and rounded edges to reduce sharp edges, is a testament to the company’s focus on user experience and safety, I appreciate the thought put into this feature.
The USMC Frog Skin camouflage pattern on the Sons of Liberty Gun Works MK1 carbines and rifles is a great tribute to the 250th anniversary of the US Marine Corps, especially with the two shades available, beach and jungle variant, which remind me of the Pacific Theater during World War II.
I’m curious to know how the Frog Skin pattern will hold up in different environments, do you think it will affect the rifle’s performance?
As a fan of the AR-15 platform, I’m interested to see how the MK1 series compares to other rifles on the market, especially in terms of performance and accessories.
I’m impressed by the design of the MK1 series, with the upper receiver and railed M-Lok handguard meshing together to create a seamless rail space, making it easier to mount optics and gear, this is a game changer for tactical accessories.
The design of the MK1 series seems to prioritize functionality and usability, I appreciate the attention to detail in the rail space and cable management features.
The fact that Sons of Liberty Gun Works is celebrating the 250th anniversary of the US Marine Corps with a limited production run of these special rifles is a great way to honor their history and legacy.
I’m curious to know more about the history behind the USMC Frog Skin camouflage pattern and its significance in the Pacific Theater during World War II, can anyone share more information?
The Frog Skin pattern was originally used by the US Marine Corps in the 1940s, it was designed to blend in with the island environments they were fighting in.
I’m excited to see how the MK1 series performs in real-world scenarios, especially with the variety of barrel options available, I’m considering purchasing one for myself.
