| Just order a set of CavArms M4 handguards from www.dsgarms.com/ and be done with it. |
Say what?.... I have the crappy single sheilders on my Home D gun. I've shot classes with them. They are adequate for the job, but the Colts are by far better. |
Sure, the Glacier guards hold heat in and ventilate very poorly. On a scale of one to ten, ten being the highest in quality and innovation, I would give them a one. For someone asking which is better, the single or double heat shield, I would never recommend the Glacier Guards. In fact, I would never recommend the Glacier Guards. For QUALITY single shield hand guards I would turn to Cav Arms. For double, Obviously Colt. |

I have a set w/ single heat shields and they suck. They get quite hot and have a lot of play thus feel like cheap shit. I am not sure who made them. I am going to try a set of glacier guards. Most people who have them like them and say they are rock solid. Also leitner wise chose them over any other M4 style handguard to use on their piston conversions. They say.... " We selected them over all the other offerings available as they performed better. It's true that a rail system will give you better heat dissipation but these handguards beat the rest hands down. Plus, they really feel good to use." They might possibly know what they are talking about. |

" From my own experience, and from what I have read of others, the only thing that cools the barrel better than the Glacier Guards, are the well ventilated ff tubes and two piece tyl handguards from YHM and MI. The heat shield reflects the heat back into the barrel. From Leitner-Wise " We selected them over all the other offerings available as they performed better. It's true that a rail system will give you better heat dissipation but these handguards beat the rest hands down. Plus, they really feel good to use. " |

Sounds like we need somebody, maybe a dealer, to do a little test. Fire a couple hundred rounds through idential uppers, one having GG, one having single heatshields, and one having Colt doubles. Then they should measure the temp of the outside of the guards, and the temp 1 inch from the guards. This should satisfy everyones curiosity, and shut up those who have no idea what they are talking about. Hell, we need a full time AR15.com "Mythbuster." WTR |
I'm glad Leitner-Wise likes them but they are wrong. Plastic is an insulator and dissipates heat very poorly. There is less air volume inside Glacier Guards than other traditional handguards. |

" Are you speaking from actual experience? Or is this just your theory?" Thats what I would like to know. I have experiene with the various metal shield handguards, and I always thought they did a pretty good job of keeping the heat in. From my experience with the Glacier Guards, the fins serve more of a purpose of venting the hot air out of the holes in the handguards. My own thought is that there is actually better air flow, than the single and double heat shields. Again, after a morning at the range today, my barrel cooled quicker with the Glacier Guards than with the others I have experienced. YMMV. I wonder if they would work better if they were Colt Glacier Guards instead of DPMS

To actually answer the original poster's suggestion: IMHO, double-shiedling handguards keep the heat away from your hand better than single shielded 'guards. Double shielded 'guards cost more, as well. You can buy a good set of double shielded HGs for $40 off LMT's website. You can get single shielded M4 or CAR15 HGs from just about any AR15 manufacturer. |
By keeping the heat away from the hands they are keeping the heat around the barrel. I prefer CavArms with a single heatshield in the bottom and I remove the heat shield from the top. Same with rifle length. Even better is a set of railed handguards with a bunch of vent holes and a forward grip to keep my hand away from teh heat. |
Yes, I put a set on an M16 and melted the little fins inside. I have never had that problem with any other quality handguards. ETA- I usually keep parts even if I do not use them, in the case of the Glacier Guards I threw them in the trash. |

I own several sets of Colt dual shielded M4 HGs and a couple sets of CavArms single shielded HGs. For the money the CavArms HGs are tough to beat. The quality, fit, and finish are excellent. Frankly I'm surprised that they aren't more expensive. I've run a set of CavArms HGs through a carbine class, and while they felt a bit warmer than the Colts they were never too hot to hold. The injection molded HGs that RRA and Bushy put on their rifles are total crap compared to CavArms and Colt. No idea about these "glacier guards" though. |
