I've eyeballed min 3 rifles so far that don't have that part (and maybe others that I didn't disassemble the front end to look specifically), 1 aftermarket barrel (didn't come with it).

Bummer...I'll have to find one of those and see what effect it has. All the rifles I've seen/heard reports from...the guys say they shoot really, really well.

Maybe I'll machine my own little spacer and see if it changes/improves anything.

I suppose by taking up the space between the nozzle and inner barrel, it'll help center the nozzle and there's less chance of a jam lodging between the outside of the nozzle nose and the inside of the chamber area of the inner barrel.

BTW... I modded 2 nozzles tonight with adjustable systems...2 different methods/variations. The guys are going to field them and report back. Takes about 15-20min/nozzle (right from field stripping the rifle, to taking apart the nozzle, to modding things, to reassembly, to test). Took 3 tries to set the velocity on one rifle (just over 400, too low and then just right)...the other one we'll chrony later.

I've got a new idea...it'll be a bit more complicated but should be rock solid.
