Title: 1/4" riser question 1322
Post by: mby852 on May 28, 2014, 12:35:35 PM

Hello All,

If I install a 1/4" riser with the crosman breech do I still use the transfer port bushing with the poly tubing or just the tubing alone?

Thanks as always.      Mike

The riser I got from bnm came with a taller transfer port.

I would just use poly tubing then. Maybe give them a call and ask them .

Ask Ron if he includes a custom transfer sleeve. Poly tubing works best when the valve exhaust port and barrel are modified with adequate flat spots on which the tubing ends will sit. Also, remember that you will need a longer hammer pin.

I will give them a call and see.  I have a rear cocker so I won't need the longer hammer pin.
