I dont have the magwell but I do have the grip and another magwell that fit on my STI polymer grip also fits on Limcat grip so it should work
you might be able to get it in black from Magnus Sports USA
see here:
it would be hard to build a 2011 that people are 'jealous' for under $4000
i priced this to $4,343.02 with rts2 and coating but no magazines or accessories
are you saying there would just be a small gap between the comp and slide with the Czechmates? If I am fitting it on a 75B it wouldn't matter? If so, can I trade mine for one of these? Thanks
