Ruger Mk IV Bolt Pulls Mark 4

thingiverse

Amalgamation of several other parts and pieces. Ruger Mk IV bolt pull charging handle. I'll try and get you the bolt specs but I went with a brass nut and bolt so there wouldn't be any rusting. The nut itself needs to be pushed into the provided slot, this will keep it away from catching on things, the bolt is a counter sunk so that it won't catch on anything.The one that doesn't have a loop is more like a rifle bolt handle but I didn't add any connection point and would definitely need superglue. I see other type handles on the market that require drilling and tapping small screws holes for attachment. The proper angle and depth to the grip portion fits like a glove and has a solid feel once you tighten the pull in place. I suppose you could put a drop of superglue but these fit like a glove and worked perfectly. Might need a little finish sanding a coat of your paint of choice.I'll try and get the measurements of the bolt, it was 30mm long, nut 6mm, screw head was 5mm but this is just from memory and my memory ain't that good.https://www.thingiverse.com/thing:2179109https://www.thingiverse.com/thing:4942408https://www.thingiverse.com/thing:3582111
