Thumbs up to Raddlock

[RP1911]

Just installed one on a USR. There is a special kit for the USR that is different than the one for the STG-556.

Took me a little longer than necessary. Just needed to file down the shroud leg (it is mentioned in the instructions). It works as advertized.

+5000000 to Raddlock--I can now assemble and shoot my FS2000 in the state of California!

My MSAR STG-556 Radd lock fit perfectly. No mods necessary. Great design. Now if he can just work on an UZI Radd lock.

I had to file down the leg too for my PSL... but it worked as advertise!
