Are handguards over top of suppressors really usable?

[SBRSarge]

For moderate fire, for instance patrol rifle training where a few shots are fired and then a break of a few minutes occurs before a few more shots, will a handguard that extends over a suppressor get too hot? Is it unusable weight?

My experience has mostly been with non-recessed cans. I’ll welcome experiences from fellow users.

Thanks

4-5 shots... don't worry
1 mag dump... watch where your putting your hands
2 dumps or more... hot is not even the word for it !

Most company's that are doing integral designs are using pretty light weight forends and shorter barrels. So in the end it's basic a wash compare to a standard 16" setup.

Retarded.

Cant shoot it without the suppressor attached.

Most of these integral "look" set ups are not really an integral suppressor.

An integral suppressor set up uses a ported barrel to bleed off pressure, like in an MP5SD.

If you plan on extended firing cycles a polymer VFG is your friend here.

If you want a 6" 300 Blackout to shoot mainly subs (or a pistol caliber) it gives you some much needed HG space. Subsonic heats up a lot slower, like pistol calibers.

Regular 5.56 will heat up fast. Too fast to be a good idea in my opinion. Plus 5.56 shouldn't be so short of a barrel that you can't make do with a HG that only covers the barrel.

Depends on duty cycle.

Jump to 2:00 - 5 mags (150 rounds) full auto into it...

The only benefit I can see is in short barrels like a 7.5" 300 BLK, to give you more rail space. Another downside is if you are using a suppressor with a quick detach mount, it makes it really hard to lock and unlock, if it's under the rail.

Lots of great thoughts for me to weigh. Thanks to all.

Use wold be for a 8-9 inch 300BLK and I was wondering about getting more real estate on the rail.

In any event, the polymer foregrip is a wonderful idea!

Thanks again!

Does it really even give you more real estate on the rail? The top rail, yes. But depending on the rail you might not have enough room to attach an M-Lok accessory, for example. I think the design of keymod would give more clearance though.

I have the extended suppressor rail for my Sig MCX, and was really hoping to use using it over my Trash panda (Whenever I get approved) but I have always been concerned with heat and so on.

Hell, even after a little bit of my BCM 11.5 with a 556 can that gas block gets super hot and makes it uncomfortable to have my hand near.

How big is the ID of that rail?

The TP is pretty large.

I will measure it when I get home. Might not even be possible it sounds like. I have not physically put my hands on my TP yet, so my estimations might have been bad going into my idea

The Trash Panda suppressor is larger than most at 1.75" OD, which makes it perform great, but won't fit under most hand guards.

I have a 6” 300blk with a screw on can under a handguard. I’ve done a couple of mag dumps using subsonic ammo and it’s not too bad. Don’t think I would do it with 5.56.

Also, as someone stated, can’t really shoot the gun without the can.
