Letting go of my Zenitco and going to KPYK.
Both were modified for Milled arsenal rifles.
Rifles in specific were SAM7r and SAM7K.
The B-10U was on the SAM7r and had a very firm fit to the receiver.
The B-11u was on the SAM7K and had a tiny bit of play but solid enough for a WML. B-11u comes with 2 basis rails one on each side.
B-10U is $SOLD
B-11U is $180 shipped or $200 with 1x basis b-2 rail.
