Frequently Asked Questions
Does RED RIGHT HAND sell the Heat Mitigation System (HMS) as a Kit? – No. Due to the nature of fitment and installation requiring specific dimensions for the barrel, gas block and rail system.
Can the HMS system work on a DD RISII Quad Rail? – No. The Inner diameter is too small (1.15″ ID) along with the accommodations for the M230 grenade launcher protrude into regions that will contact the HMS. Also Riflespeed Gas blocks do not fit within a DD RISII rail system.
What other rails work with the Heat Mitigation System? – We have a Customizable RECCE LMG upper option and it list all the approved rails that we have confirmed work with our HMS. Additionally, any Quad Rail or Off Set Mlok (Like the Geissele MK8) with an Inner Diameter 1.3″ or Greater will work. For Mlok only rails with no off set mlok, a Inner Diameter must be 1.5″ or greater to allow use of the Mlok T-Nuts.
Can the HMS be adapted to other barrels? – Yes, but only if they match our approved HBAR Profiles. The Classic .980″ profile and the SOCOM .875″ profile. ***DMR/SPR Profiles don’t always follow the .875″ Socom profile.
Does the HMS fit on Tapered barrels like the C.O.R.E style profiles? – No. The HMS is a one to one press fit on a straight profile HBAR barrel. It’s not made for taper profiles.
