JG Sig 550 Internals
 

Hey Guys:

For those with experience upgrading the JG Sig 550:


1) Do Air seal nozzles and Cylinder heads that are designed for the TM Sig series (551/552/550) fit the JG model?

2) what size bushings does it take (i've noticed lately that some JG guns use 7mm bushings).

Thanks!

Yes the air nozzle should be the same as all the sig series rifles (550,551,552,etc) cylinder head should be a CA type v3 ( flush front no key). The best way to check bushing size is to pull that mechbox out and check what size of bushing you have ,my best guess would be 6mm.
