I picked up a J420RM reload kit. It mentions "enlarged aft closure". The nozzle fits the standard aft closure. I am confused, I can not find any info on the enlarged aft closure on Aerotech website. Anyone here know anything about this?
Thanks Bill

As I recall, once upon a time the 38mm aft closures came in 2 different sizes and the smaller of which is no longer made and all reloads now work with the larger aft closure.

And if by chance you get a smaller one, just take a unibit and enlarge the hole.

Thanks... Luckily I have lathes and mills.
