I would highly recommend this NERF gun.
The modular design of the gun is great , the build quality is fantastic and it is much more accurate than Mavericks. We own two Mavericks well. The light "laser" sight is very cool too.
As far as "jamming" issue goes, mine has yet to jam.
My only minor niggle is that stock moves a tiny little bit; but, that is price of modular design :) .
My only recommendation other than buying a Recon CS-6 is to pick up some extra clips and ammo.
Hope that helps.
