I have a set of Colt,RRA and cav arms all M4 fat ones.The polymer in the cav arms is superior to both and have better heat dissipation.The Colt and RRA feel the smae to me except Colt has double shields the others single.So maybe Colt uses a lower grade polymer.I know there is 2 ways to do it thermoset and compression molded I dont know wich the respective companies use but I think compression is stronger although if you use an inferior polymer it probably dosent matter what process molded it.

You should also try DPMS Glacier guards. I'm really happy with the set I tried out.

My buddies got the glacierguards unfortunately they hold in the heat on an HBAR.They came on the L&W conversion.

I like mine. They stay pretty cool. After some quick fire of about 60 rds or so smoke just pours out the top vent holes but the handguards are still comfortable to hold. They stay much cooler than single heatshield M4 guards. I have not tried the double heatshield guards so I don't know if they work better or not. Leitner Weise said they are the best M4 handguards you can get. They claimed to test them all. Plus you can get them for less than $20. |

You're comparing apples and oranges...
The CAR handguards are smaller... like on this Colt AR15 A2 CAR Model 6520  The Colt M4 and RRA R4 Handguards are very similar R4 Handguards:  CAR Handguards.  The M4 / R4 Handguards dissipate the heat better than CAR handguards. |

They also have a taller cross section and fill the hands better.

They do work well. In my experience they do vent the heat out very well. Handguards that I had with the single shields, held the heat in.
That systm runs hotter than a regular type upper to begin with. Talked with the guys from L&W, and they said the Glacier Guards cool the barrel better than heat shields. |

The system dosent run hot at all,no heat in the upper or carrier just the barrel and I was warned by 48th highlander from grenadier precision that having an HBAR would make the glacier guards useless and he was right.
