Re: M10/47 SABRE Upper

All these talks about drilling a hole still. Would there be a way of using the holes for the stock?

Would not get BATFE approval.

MHO, YMMV, etc.

Not an approval issue, as the recoil mechanism remains unchanged, but how would you attach the stock? The attachment point needs to be quite solid in these conversions (compared to OEM requirements) due to the stock housing the recoil components.

I believe that the point of using the stock bar holes is to get away from using the conventional M16/AR-15 type recoil mechanism and stock assembly that requires drilling a new hole in the back plate. Such a "drop in" type unit would not likely be approved by the BATFE.

MHO, YMMV, etc.

I didnt think the issue was being "drop in" or not. I thought the issue was whether the upper would be compatible with the semi auto variants of these guns. Do the semis even have the stock holes?

The question specifically addressed was to that of using the rectangular stock bar holes instead of drilling a third hole in the back plate.

Regardless, people can believe what they want to believe, and do whatever their hearts desire. I wish them all the best.

ATF FTB just don't want the upper to be a firearm. They don't care which hole we use (insert joke here) to accomplish that, as it is irrelevant.

Precisely!
If the upper can be made to fire a round without a lower it becomes a firearm, which, when placed on a registered lower so it can fire multiple rounds with one trigger pull, then makes it a "new" machine gun and thereby contraband.

SABRE M10 DI Trunnion drawings done (I also have the stp files). I have contacted a company about a quote and should hear back soon. I have the raw materials to make a couple of these if there is a member here that would like to collaborate:

The M10/47 project is dead unfortunately. I cannot find anyone to 3d print the pieces in plastic for less than $600 and no one is willing to machine the receiver halves in aluminum. I got quotes on doing a DI version of the trunnion, but those were cost prohibitive considering the fact that I would have to also convert a carrier to work with the lower. I got a quote on the 1st Gen SABRE gas blocks so that I can do caliber changes more easily with my existing SABRE upper. I will be ordering a run of those next week, and was wondering if anyone would be interested in purchasing one? The cost would be $125 plus shipping per gas block (or $100 if we order 10). Anyone interested should send me a PM.
