Morgan's Riflemen or Morgan's Rifles, previously Morgan's Sharpshooters, were an elite light infantry unit executing his tasks because it was equipped with what was then the cutting-edge rifle instead of muskets allowing superior accuracy at up to ten times the distance of the typical troops of the day.
MK10MR Designated Marksman Rifle
At Sons of Liberty Gun Works we believe in Quality Mil-Spec or better parts. We believe there is no substitute for quality and that your gun should be built right the first time, ready for hard use right out of the box. We believe a quality Bolt Carrier Group and a quality, accurate and long lasting barrel are the heart of a Combat Grade weapon. We believe in properly tuned weapons using the correct gas system length and quality buffer system components such as the Mk10 Hybrid Buffer system and Sprinco Tactical Buffer Springs. We believe in our products and we back them up with a Lifetime Warranty. Our weapons our meant to be used hard and go in harm’s way, they won’t let you down.
All rifles are test fired twice in shop to ensure proper function.
The Mk10MR is a no holds barred sniper rifle, capable of 1/2 MOA, with a fantastic Geissele SSA-E trigger, Raptor charging Handle, magpul PRS stock and your choice of an 18" or 20" Match grade barrel.
At Sons of Liberty Gun Works we always tell our customers, its not what a rifle company tells you, it’s what they don’t tell you. Below you will find the complete specifications on the Mk10MR. We have built our guns to run through years of hard use, and we have nothing to hide.
