0% AR lower fabrication for nySAFE BS compliant rifles.

[Meketrefe]

This is the idea....

Create a simple design that uses simple cuts that can be made with a high speed saw and/or mill.
Here some idea courtesy of our friends at the weaponeer forum.

Cuts can be made using a set of templates....


i


Go to the local ACE store and buy a set of hex head bolts either parkerized or stainless steel.




Then with allen key finish the parts and then just assemble as any other lower...

Why AR fabrication?
Very simple, I have been thinking a few simple variations that will make this a nice alternative for those in communist states like ny.

The only part that is a bit more tricky is the back piece with the buffer threads and the L type tapered shape and curves.

But I have the solution to change that part as follows:

Create a bufferless AR by making a pocket for a small buffer and then cut the carrier for another small buffer embedded in the pocket.
Both parts are easily made using a stainless steel rod as a guide and a small plug to work as weightless buffer. Will need to adjust
the gas to reduce the backpressure that is a good thing.

so what this means now we can configure the grip slot /tongue to be something else that will take a number of regular stocks like
a contender stock could make a nice one with or w/o a cheek raiser.

So this means with a target crown or end cup or barrel sleeve pinned this will make it compliant with the safe act BS but all the
remaining parts will take regular uppers, triggers, pins, sears... etc..

Additionally I am thinking making the slot a large larger that means a loose fit magazine (still functional) but will take an apapter
for Glock magazines so pistol calibers could be used.

There is no point on making a lower unless you are going to add some value. I think this gives a few nice options before one
cuts the templates.

Meke this looks like a great idea. Is it still in the concept stage or is it something that can be made/bought? Not sure that I completely understand the buffer substitute process but all in all seems to be something a handy guy can do. Do you have any more info on this?
Thanks.

[Meketrefe]

The back. Pidce is the only tricky one... hummm.

I actually have drawings to make those parts. I just might do it one of these days, if I ever get some free time at work.

The hardest part is stomaching the cost of the tap to cut the tread for the buffer tube.

What if you skip the threading? Make you own buffer tube with a thicker wall that can be held in place with pins.
You might have to modify a stock to fit but so what?

Interesting idea. I'd have to put some more thought into that one.

[RayKnobs]

If that whole back assemble was two pieces you could use it to clamp the tube in. Think about how the 10-22 barrels are held in or scope rings

[camper4lyfe]

I've never held a 10/22 so I'm not sure how that works, but I get the scope rings.

Ideally you'd like to be able to use a stock buffer tube if at all possible. It makes life much easier in the long run (plus they're not easy to make, for my skill level anyway)

[Meketrefe]

With the design I have in mind the buffer can be threaded in a lathe and then cut to be assembled. One could thread several inches and then with that section cut 2 or 3 smaller pieces
to make the back piece. So no need for expensive taps. But even a regular buffer tube inserted in a plain tube with a tight fit can be anchored using a few small set screws. This is
easy. Also making a custom tube like ray mentioned or even bufferless is not that complex. But the bufferless system is something that would be quite unique.

I am also thinking a bot stop that allows both the use of regular magazines and VLD centerstack by simply switching a small pin. This would be a nice addition for those who want
to use an upper with a special / wildcat caliber with big bullets for hunting or something like the 6.5TCU for example. Additionally an adapter that one can put to convert to
a pistol upper that takes glock magazines. This is actually not that complex neither, I have the design for this part already.

I can cut all this parts but I am thinking how to make the back so anyone with some simple drill press and high speed saw and a few taps and drills could do it.

[Meketrefe]

Anyway this is the tap... it is not so bad....

[camper4lyfe]

That's not bad at all, for price. make a couple receivers, or use it and sell it, and it's not horrible.

[Calculon]

Can someone pls post or pm me a link to the plans/drawings/thread on this? Interested in learning more and have been unable to find after a brief search on weaponeer.net.
Thx.

[Meketrefe]

This is the file but what I am saying is there is a much easier design for the cuts than this one...

[Meketrefe]

I mean there are some cuts in the file that are very similar but I want to simplify the back one so many people could do it on their own with a few common and inexpensive tools.
