I'd just purchased a set of handguards off Gun Broker.com, the same dealer has many listings for the Bushmasterr M4 handguard. One listing says M4 handguard with heat sheilds,his other listings says M4 handguard with double heat sheilds. I'd order the ones with double heat sheilds. Question is, does Bushmaster put out two differnt M4 handguards? These do have double heatsheilds?  tg |
I just bought some DPMS M4 Handguards from a guy on Gunbroker and they were called "Glacier Guards" they have vertical integrated heat fins molded in the the entire inner portion, they will stand 575 degree's of heat generated by the barrel! They seem to be very heavy duty and stronger I guess the plastic is a glass/nylon reinforced plastic from what I am told hey for $35.00 bucks it seemed like a deal they fit perfectly onto my M4 Bushie!!

I read here recently that Bushmaster was offering a new type of hand-guard for the carbine. I cannot recall whether the "new" part was double heat-shield, or some other enhancement. I DO recall CJan_NH commenting on it and offering more technical insight than I have to offer. |
The problem with the theory behind the glacier guards as I see it is the heat shields are to keep the heat away from you hands and the fins in th eglacier guards bring it to your hands. |

Older discussion on this subject. I purchased a set from BM earlier this month here's the pics.    They do have double heat shields. |
