Will Benchmark Rt Frame Fit Stock Mag?

[gonefishin]

Just a quick question.

I am selling a Benchmark single trigger 45 frame that came with my older RT (I just bought an Intelliframe - AWESOME!!!).

I have a few people looking to buy the old frame, but they want to know if it will fit their stock mags. Since I am relatively new to mags, I don't know.

Any help would be appreciated.

Thanks -

it will but it will need a bushing..... the banjo bolt on the RT is bigger then the one for the mag as the mags did need to have air going through it....

you or they can get the bushing from either benchmark(PTP nowadayz) or from AGD.......

Wouldn't they need the roller bearing type sear and screw pin in order to install it on a regular Mag? I do not think the old RT rail (nor newer) had groves for the stock Mag sear pin do they? Not sure. But I think not. So if that is the case they will need these and them things is expensive...

from what i read he is looking to take a bench grip and go from rt to normal mag....

it should work just like taking my Zgrip (which is the RT style) and adding the bushing to be used on a normal mag.....

on a personal note.... i not fond of how the benchies work the sear rod.... ie moves it up and back... it just sems wierd to me.... but it does work....

Oh yea! Now that I re-read it he is talking the grip frame. For some reason I was stuck on the rail. Never mind!!!!

Virus is right, just the bushing is needed. AGD has them too and somebody said a PT spacer would work. Never tried it though.

Can someone post a pic of what a bushing looks like?

Thanks everyone. I will point the interested buyers to this thread.

it fits....

hi, i bought the benchmark frame in question and thought you all might like to know how i got it to fit.

as far as the bushing, it's not a strict neccessity as the field strip screw head is large enough to hold it in place, but since it may wiggle or mis-align because of the gap, i put a bushing in anyway. i got a nylon one from a hardware store and trimmed and filed it to fit.

an unforseen issue i ran into, is that the top of the benchmark frame is thinner in height than a stock frame. when i put the front frame screw back in, the barrel would not turn or come out since thestock screw ended up being too long. i bought an allen head machine screw and ground off some of the thread end until it fit.

both operations were done by eye and through trial an error (since i'm no genious, i had to keep at it).

the whole process cost me a half hour in the hardware store, an hour of labor, and less than a dollar, including spare screws and bushing incase i messed up the first ones (and i did).

i havn't shot it yet or even put air through it. i'll post how it performs if any ones interested.

Good to hear you found the solution. And yes the wiggle from not bushing it will eventually lead to the valve pushing back ever so slightly to the point the sear will not make proper alignment with the On/off pin. So good you did take up the slack. But watch for wear on that plastic one. Brass is more permanent. Go ahead and see if you can get one. Almost all Benchies I have encountered resiult in the fore grip screw being a bit too long. Your method of fixing it is common. Others, including me, just put a washer on to shorten the screw. Either way works fine. Yours is easier in the long run as you might accidently lose the washer.

Good to hear you got it all up and running.

thanks for the info....

dude, your reply made me think of something i'll have to look for. since i did the bushing by eye, i'll need to make sure the sear end lined up properly with the on off valve pin.

i'm not sure how much room for play there is between the pin and the sear. not much due to the very small size of the pin.

i didn't even think of the washer. i tend to think of the hardest solution first. that usually gets me into a lot of trouble.

i wanted a brass or some kind of metal bushing, but the right size wasn't available. i'll keep looking. does anyone sell them?

thanks!

update

hi all, it works fine. looks good, feels good and balance is nice.

i did have an issue with an aftermarket 6 hole bolt, but that was solved using an older and somewhat compressed spring. any tips on this? should i try to compress new springs? how would that be done? i guess i could put one in between two pieces of wood and put a rock on it :)

trigger pull is awesome. just as good as having the sear worked and the wide trigger makes it nice to handle.

i did scrap the machine screw i had bought and ground to use in replace of the stock frame screw. it was vibrating loose. i went to the washer method that was mentioned in a previous reply, thanks very much for that idea.
