Runs cooler - Adams Arms P Series Micro Block Carbine Length Piston Kit

I slapped this in an aero upper and barrel. Samson Evolution series guards perfectly house the system. Then I put a JP enhanced bolt and trybe firing pin in. To top it off attatched my Banish 30 suppressor. Fires like a champ and a joy to shoot. Noticed suppressor and firearm didnt heat up as quickly. System was designed around mil spec barrel nut, just keep that in mind. Google compatible foregrips is what I did.
