Red Right Hand’s development of the 20” RECCE LMG Uppers
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, 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.
RECCE LMG Production 2024. All Orders placed are built to order. Orders are build in order received. Thank you for your patience.

GREAT UPPER AND MIDIGATES HEAT AMAZINGLY. IT’S ALSO VERY ACCURATE AND CAN BE USED AS A DMR UPPER IF NEEDED. HIGHLY RECOMMENDED

Initial impressions have been extremely impressive. So far I have 500 rounds of PMC xtac (55 and 62 grain) 5.56 through this build. 20 for sight in/gas system adjustment and the rest rapid fire with a fostech echo trigger through magpul D-60 drums and Surefire 60 round quad stack magazines. Once the gas system was adjusted (setting 7 with cold weather plunger installed is where I ended up) there have been 0 malfunctions. Build consists of aero lower, springco red buffer spring, H3 buffer, fostech echo trigger, magpul bipod. The only modification I made to the upper was adding a VG6 epsilon muzzle device. Accuracy on semiautomatic has been quite good. Learning the fostech trigger has taken a little time but overall I’m very happy. When I initially inquired about this upper Customer service was great. Response was quick and they were more than willing to help me plan out a build. 500 rounds has been a good indicator of this upper’s capabilities. So far I’m very happy with it for my purposes.
