(Keep your gun clean)
For testing I had a well used A5 and when I removed the cyclone
there was still paint between it and the body. The paint must have been
there for quite some time but I dont know exactly how long. When I cleaned
the halves all the paint that was bubbled up from where the paintball residue
had sat came right off. If you don't want your gun loking like this I suggest
you kepe it clean..... OR have Spec OPs Dura coat it.
(Burr inside half)
While testing afew A5's I noticed one had a burr on the half that
attaches to the cyclone. It rubs on the rear bolt / hammer. When I got
my A5 I took it apart to polish the internatls and it had this EXACT same
burr. I guess this gun and mine were from the same production run. I used
a stone to remove the one in my A5 prior to polishing the internals.
