It's a short stroke piston kit ? - Adams Arms P Series Micro Block Carbine Length Piston Kit

This is my third Adams Arms kit i purchased. I'm not sure why i continue to buy them. They do keep the firearm cleaner. They add a certain level of confidence that you can send 100s of rounds down range all day without loading up the rifle full of spent gas and carbon. They sure do work nicely. If you are in the market for a piston system make sure you purchase the adjustable gas feature. especially if you are contemplating a suppressor in the future. This is a well made and easy to install piston kit. My biggest issue is wait times for these kits.
