I seem to recall it came from Patrol base, I'll see if I've still got details. Used an adapter on place of the standard flash hider to bring the threads up to the usual 14mm -

Cheers mate, I'll probably do that then. Shame about the mags. 

G36C rails fit the sides of the A1. Not had any issues with mine, it's a great little gun. Use it as a primary at the local woodland site on occasion.

When I bought my mp7 wgcshop had navy version in stock but just checked and it's gone. Patrolbase sells the A1 version if you can't wait. 😄
