Aluminum handguards (tubes)

[wild_wild_wes]

I'm looking to build a low-cost long-distance AR using 6.5 Grendel. I don't need rails on it, just a bipod stud, and was considering getting one of the plain tubular types. How hot do these get during firing?

The aren't going to get too hot firing a 6.5 unless you have a ton of money to burn. I just finished a Redback One class with my DDV7 and it didn't get too hot to run without gloves.

So far, I've liked Rainier Arms' evolution rail. Comes with a heat sink that slips over the stock barrel nut. Works pretty good.

I was still able to heat up the evolution rail so that when I touched it without gloves it was not pleasant. Round count and time frame make a difference.

Don't get me wrong, it CAN heat up. It's just less prone to doing so.

Troy TRX or the Vtac are both GTG.

I have had them pretty warm in the past but nowhere near burning your hands...and they cool off pretty quick too

Troy TRX here and normal shooting building heat is not an issue at all but under small class conditions with constant fire I use light gloves.

I just happen to have an Alexander Arms composite tube handguard for sale. Pm me if interested. It's in the equipment exchange.

My m4v7does not seem to get too hot, but like anyting else, if you do a few mag dumps it will get hot.

I have found that weather conditions make a big difference. On a 100 degree plus summer day with the sun blaring down, a TRX extreme can get very hot very quickly. My DD and Centurion quad rails seem more resistant to overheating (probably due to the increased area acting as a radiator) even without heat shielding. I got some squid grips for my TRX, but have not done any high intensity shooting on a hot day with them.
