Pump arm rail slot specs and enlarged sear slot body specs

[z-zero]

I have searched and have found nothing about the specs for the pump arm slots that allow a pump kit to be installed and work properly. I asked a Tech in a email and got post it here, so I am.

Could someone at AGD please put up the drawings for the body rail with the pump slot and its measurements? And of course the dimensions for the enlarged sear slot on the compatible bodies?

Get the drawings and white out all the unnessesary dimensions, so us lone pumpers can set up a pump Mag. Something I could give a machinist with my parts and he could do it easily. Like the pump Rod specs, that is great! There seems to be some sort of ramp in the slot on the rail and body to allow the rod to contact the bolt correctly but I have seen nothing else on it.

Also from reading the thread advertising the pump kit kits now available in the store:

Am I understanding that ALL minimags were made and are made to be compatible with the pump kit? Tom mentioned it twice, but was not sure if thats what he ment.

Any help would be great,

I've taken some measurements from a few guns I've seen at tournaments for the parts needing machining and hopefully this week I'll have it working.

PM me and maybe I can help you out.

I found this on a top secret webpage. I hope this helps.
Also, I do believe my local store may have a couple of those rails (old style with groove) just laying around. Something like $30. PM me if you are interested.

well the pictures arent the best. i chose the clearer of the bunch. i used the ruler to give you something to scale the piece from. the big side of the ruler is 1/16 of a inch the small is 1/32 of a inch. this is picture of my pump mag.

Wow those pics help alot,

Is there any kind of ramp in the rail?

Thanks,

yes there is a ramp. its a 2 angle ramp. one angle then changes to another. also the slot in the rail is radially cut from the center of the body. in other words its not just straight ip its leaned inward. your best bet would be find someone in the for sale section that has a rail with the slot. thats what i did.

also i found that the pump arm comes with a little oring to hold stuff together. make sure you want it on before you put it on. its not fun getting it off in one piece. i kept mine off so it would be easier to make spacers to limit the stroke.

this is my mag. http://spyderea.net/forum/uploads/co...h/mag15deg.jpg
