.68 special mods

i have a few of these specials and i really enjoy playing w/ them
the noise, weight, plume of smoke. etc

one of them i bought had a brass tube in the front that the bolt rode in
but i broke both the bolts that came w/ it. not thinking much about it i took out the spacer put in stock bolt and kept using it.

i came accross an old thread that was selling aluminum bolts but was to late...and learned this was an old mod to decrease ball chop at 8 $ a bolt i hate to grind stock ones down to fit just to break them soon after

any ways was there any other homebrewed mods that people were doing to these "back in the day" ?

thought about lightening the hammer.
or drilling out the side to run the gas line to a different position.
i just really dont want to ruin stock parts if it doesnt work well
but would love to tinker on these things if there was worthwhile mods.
thanks

I really loved my 68-Special. Bought one as soon as they came out in 1990. Kept using it long after all my other teammates switched to mags and cockers.

Those anti-chop inserts were popular, but I never liked them. I LIKED being able to squeegee my barrel, and I never had a problem chopping balls. However, paint was much bigger in the old days. Today, you are often forced to use small-bore paint at many field.

The rubberband trick mentioned above does work, but in the old days that was often frowned on, and sometimes forbidden because of the "other uses" for the rubber band. Should be a problem today, though, as the "other use" seems to have been forgotten.

An alternative to the rubber band is a simply heavy-guage wire, (like from a coathanger) that you wrap around the barrel-retainer screw, then bend across the access port to hold the balls in. The field I worked at in the early 90s would actually sell these for $5.... probobly cost 5-cents to make!

Other popular mods were the "tilt kit". With it, the forward and rear receivers were held together by a large HINGE held together by a large thumb-screw. WHen the screw was loosened, the forward receiver would "tilt" forward, and basically allow you to completely field strip the gun, quickly, in the even you chopped a ball.

I sure it could be replicated easily, though I don't remember exactly what they look like?

Also popular was bypassing the internal gas-line. Likewise, nobody likes backbottles anymore. So people would hook up a bottomline, linked directly to the valve. The valve "floats" so a hole in the receiver would have to be large enough to allow for some sliding. The bottomline ASA itself is harder since they are much less common today. CCI still makes lonestar adapters, but they are pricey. Almost easier to track down a 45-frame for the lonestar, and use a generic ASA duckbill.

Likewise, I've seen people make simply vertical ASA's using Automag vert adapters. Then you can use an old-school gas-thru stock on the unused rear ASA.

Hopefully you have the tippmann feed adapter. Do they still make those?

OH that makes sense. Kind of like why cockers have beavertails then.

MCB is heavily spidered by search engines, and that kind of information can get picked up.

But yes. That was something we refs had to keep an eye out for. HOWEVER, the 68-Special cocking rod itself is held on with rubber bands.
