Hi, I'm new to the forum, and somewhat new to the AR world. I bought my first last January and now I have 4. My latest is a 16" 300BLK with pistol gas. It's pretty plane Jane, but very fun to shoot. I went with 16" to avoid NFA...

Anyway, I just got my form1 suppressor approved and am in the process of finishing up building my can. My concern is over-gassing my rifle with the can on since I only have a standard gas block. I know it's recommended to use an adjustable block when suppressed, but will it hurt anything to not use one?

Currently, I'm shooting supers through it. 125gr Nosler BT's with 17.2gr Lil' Gun.
