Includes 4 mags, fill probe, sling tube clamp, 1/2x20 thread on end of shroud to add a moderator, and a DonnyFL end cap thread protector., 
and I’ll even throw in the sling. No issues with this gun. I didn’t have a chronograph so no info there. Now I have one but don’t have an air supply. $700 plus shipping and PayPal fees if you don’t use F&F.
