Finishing up my build and have some questions.

Started with a Gen 2
- Lancer 10 inch hand guard
- ILWT 4.5 inch 1/2x28 threaded barrel
- PTR Vent 2 suppressor tucked under rail for SD Look
- Sig Collapsable Stock

Question is this. With the suppressor tucked under the hand guard I know the suppressor will get stupid got when using an FRT. what are guys using (other than gloves) to deal with the excessive heat? I’m trying to stay as light weight as possible due to the wife having a bad shoulder and not being able to shoot a 16inch AR, so I don’t really wanna cover the entire fore end with rail scales or panels.

Looking for opinions from people actually running tucked cans.
