    AR MK2.jpg I have an old Bushmaster AR M4 with fixed carrying handle. I added a rail for a grip under the forend guard. Now the screws forced me to leave the heat shield that is on the underside of the forend grip off. Is that heat shield really necessary?

    My AR isn't full auto and I sure am not gonna fire 20 mags as fast as I can. So... is it necessary?

    Thanks!

    Depends entirely on how much you fire it. I don't think you will damage anything but it will certainly transfer the heat to your hand faster without it.

    The heat shield is for you. Spend a day shooting it and see if you think it’s necessary.

    This is why Knights puts a head shield in their M4 RAS lower. But if you use the fore-grip and don't do mag dumps chances are you won't miss it.

    Just replaced the handguard with a railed one. You can get them cheap.
