Not complete - Adams Arms Standard Picatinny Block Piston Kit

Now I’m sure it will work once I get all the parts! Not OP fault but bolt spring is missing. Also if you get the pick version they no longer include parts that you need to complete the build. No end cap for your hand guard. I contacted Adam and although they did offer to send the spring informed me they no longer include the rest of the parts and you have to purchase them on a kit that should come complete. To be truthful their customer service is lacking big time you call they won’t answer you can email them but they are slow to respond! At your own risk
