Hi guys,

I recently bought a C93 with a bolt gap of .006. i bought some +10 rollers from RTG to bring it up to 0.16. However, the new rollers do not fit into bolt body easily, in fact they won't recess without a light tap from a small rubber hammer. The bolt is marked 'BT'.

When I install the bolt with the rollers onto the carrier, it will not spring forward when rotated into place, the rollers will not retract.

Any ideas or suggestions?
