Red Right Hand’s RECCE LMG-CL Uppers (FNH Chrome-Lined HBAR Barrel) Limited Production Runs

RECCE LMG-CL Production 2023. We build this uppers in batches. We are able to source a limited numbers of these barrels produced by FNH. Due to low-demand for this style of barrel, the OEM doesn’t have these made to often and so the stock is limited.

20″ HBAR Button Rifled Barrels made with MIL-B-11595E CMV by FNH. Feature a 1-7 Twist rate, 5.56 Nato Chamber , MilSpec Phosphate Coating, Chrome-lined and 1/2-28 Threaded muzzle. Gas ports are proper mil-spec sizing (.092). These barrels are classic FNH Reliable, Very accurate and smooth shooters.

All Orders placed for RECCE LMG-CL are “pre-orders” for the limited Production batches.

We will resume Pre-Orders for RECCE LMG – CL uppers when we have confirmation on more FHN Chrome Lined Barrels from my supplier.

(Update 8/10/23 – Our OEM provided timeline for barrels and Quantities, as of now, we are getting close to the “earliest possible date of delivery”, that being said, a few more weeks can and likely should be expected. However, we likely will offer Pre-Orders in the coming weeks)

Thank you for choosing Red Right Hand LLC!


Development of the RECCE LMG Upper Line:

Our goal was to create our unique LMG upper inspired by the classic COLT LMG. Designed and built to handle heavier volumes of fire over standard Carbine type uppers. We utilize a HBAR Barrels instead of using lighter weight profiles such as Government, Pencil, Hanson, and other light weight tapers. In addition to the HBAR barrel, we designed and produce our enhanced cooling system to be built in.

Red Right Hand’s Heat Mitigation system (HMS) is designed to help keep the overall temperatures lower and aid in cooling of the barrel and gas system faster than a standard direct impingement system. Our 6061 Aluminum heat sinks draw and disperse heat faster than just steel. These simple heat sinks use thermal dynamics via the use of Aluminum on Steel, drawing heat away as it builds up in the heavier profile HBAR barrel, and adds additional surface area to aid in cooling. In addition, Our H.M.S Copper/Nickel Alloy heat sink coil pulls and disperses heat from the straight gas tube. This keeps the gas tube from expanding and passing more gas into the system as well as prolonging the lifespan of the gas tube. This reduction in heat prolongs life of the upper, keeps the operator safer, reduces the risk of cook-offs and helps the overall thermal signature of the weapon system

Choosing the right gas system to fulfill the requirements for the modern era: We also chose to use the straight gas tube over the traditional bend gas tubes. Mil-spec bend gas tubes allow build up of heat in those bends which can lead to failure. This issue is reduced drastically with a straight gas tube and additionally lead to a more constant gas pressure to the carrier key. Another major design part which we felt was necessary to have with these uppers was the ability to adjust the gas. We looked to the firearms market to find the right OEM choice for our product. After testing many others, we chose the Riflespeed Gas Controls. Hands down preformed the best and has major advantages over the others. No need for any tools to adjust and the Riflespeed gas control is very user serviceable. Having this ability to adjust the gas to the system can allow the end user to tune not only the amount of gas you want for operation, you can tune for whatever ammo, buffer weight or trigger system you may have equipped in your final build. Major advantage to using Riflespeed also comes when adding a silencer to the upper, the gas control can tune right into the back pressure profile of whatever silencer you use. Trimming the amount of gas entering into the system also helps keep the overall upper cooler by lowering rate of fire and limiting the extra heat built up by excess gas.
