Plumb Precision introduces its Patent Pending Carbon Fiber Thermal Barrier Handguards for FN SCAR rifles. Designed for minimal thermal transfer during sustained fire, these handguards demonstrate no deflection under pressure and maintain low external temperatures. They offer compatibility with various barrel lengths and suppressors, with future models planned for more rifle variants.
Plumb Precision states “Plumb Precision Products has an extensive library of proprietary product solutions for many modern small arms. One now being made available is the Patent Pending Thermal Barrier Handguard.
These are derived from a Plumb Precision Products submission into a USSOCOM SBIR. They are now being made available to the public on a very limited basis. The requirement was minimal thermal transfer to the surface of the handguard post sustained FA fire (300 BO) of an SBR. Additionally, there was a requirement to not have a deflection of > 1degree with 30 lbs. of pressure applied to the HG.
This HG passes both tests with no deflection. The bare CF can keep an external temp of 90 degree to a 1.5″ thick suppressor having an external temp of 450F. The CF goes to 135F when the can goes to 600F. There is an additional element that drops the temperature transfer even lower.
It allows access to QD for 13.5 and 10.5 barrels and recessed suppressors. They are being made available for the FN SCAR 16 and 17 rifles. Other variants are planned such as the HK MR762/417 rifles, the Sig Sauer SPEAR, Genesis 12 Shotguns, and the AK series of rifles.”
