christhesecond Posted July 18, 2006 Report Share Posted July 18, 2006 simple question, do the ca m15a4 cqb's, m15a4 ris (2006) and the m15a4 spc all use the same gearbox? i think they do because they all use the 7mm bearings and the more simple ca armalites such as the m15a4 tactical carbine use the 6mm bearings. cheers chris Link to post Share on other sites

***Ice*** Posted July 18, 2006 Report Share Posted July 18, 2006 Nope, they don't buddy. They all use 7mm bearing gearboxes, however in the RIS and SPC all other components are the same as a carbine or tac-carbine. The CQB has many other modifications: Vented alu bearing piston head Bearing spring guide Thinner spring Metal cylinder head O-ring air nozzle Newer gear set, with 4 anti-reversal latch catches and CA markings (although one of my CA36s came with this gearset, and the other didn’t, so it may be in other M15s now) New cylinder New selector plate You may find this useful I still think they should have used a flat faced cylinder head and a poly piston head, but you can't expect them to get everything right.

tgrillo Posted July 19, 2006 Report Share Posted July 19, 2006 hmm, how good is the compression in the CQBR? As good as TM/G&P? Link to post Share on other sites
