Figured I'd pop over here. I've developed quite a collection of Mags in recent months. Currently I'm sitting on a dozen or so, 3 RT Classics, one Pro, a Retro valved Classic and the rest are Classics/Minis. Had tons of fun, its great using them on the fields. The markers are older than most of the players usually.
I've done a few chop n crop projects. I did a Spyder E frame Mag, kind of neat. Did a Longbow type build with an old Spyder clone body. Have a Pneumag project but it isn't perfect yet, should be soon.
Something I completed yesterday is really awesome, made a mechanical trigger lock when there is no ball in the breech. Pretty much a set of eyes without eyes. 100% mechanical and 100% invisible on the outside. I have shot it with Classic level 7 valves, works great there, but it more than likely won't work on an RTing valve. The safety is still there and fully functional. It takes some milling, nothing too hard and if you have a steady hand you can probably get it done with a Dremel. I spent about 2 weeks trying to come up with a design, only took 2 hours to complete from scratch so anyone can do it. If there is interest I'll post pictures.
Hope to be a contributing member on here, looks like a good group of mature paintballers. Not exactly common anymore.
