PneuMag from Standard RT?

[JRingold]

Is it possible to make a Pneumag conversion from a Standard RT?

I haven't seen anyone try it, but I'm looking for some initial feedback before I do such a thing.

Is the ULE trigger Kit a requirement?

Pneumags have no preference of on/off's. Just note, the heavier the on/off, the higher the input LPR pressure will have to be, making an overall harder pull. I plan on building one RT based to begin with, then upgrading to ULT.

But yeah, it should work no problem.

Jay (RRFireblade), the inventor of the Pneuframe prototype for PTP, said that the ULT was not only unnecesary, but it decreased performance. A stock on/off is supposed to be used, not the ULT. There should be no problem doing the mod to a Classic RT. It should be exactly the same. The foregrip will simply need to be drilled and tapped for an lpr instead of the VA being drilled and tapped.

You can mount the LPR side saddle on one of those extra 'accessories ports' on the side of the old RT rail.

Also, make sure your ram hits the leg of the sear where the trigger rod connects for the best leverage.

That's what I was thinking, that way I wouldn't have to drill and tap anything! It would just be a LPR hanging out next to the valve...
