Preacher Roller and Boltface Tweak
Earlier I had promised that I would upload the mods I made to get the Preacher ( a Remix of the breacher to cycle Properly). Basically these mods increase the size of the roller to 25mm ( which holds the lifter up) and shave of 2mm of material from the bolt face to avoid a clash.
let me know if this helps get any of your blasters cycling.
P.S. The pump on the breacher still needs a bit of dremelling to clear a clash, so if your blaster still isnt behaving take a look at your pump clearance.
