As
of the writing of this article, we are starting to see a little relief
of anything related to AR15 rifles. Everything from ammo to charging
handles are starting to trickle in from backorders long ago however it always seem the
part you need is out of stock to complete your AR lower. In this case
my naked stripped Anderson Manufacturing Lower receiver had sat far too
long in the Liberty Safe waiting for me to find all the right parts to
get it into action. Instead of chasing parts. I decided to place an
order for a lower parts kit with Barnes Precision and patiently wait.
But then I had an idea; could I salvage enough equivalent parts from a
hardware store to get a minimally featured AR lower up and running? What
parts would I absolutely need, and what could be omitted?
OPTIONAL AR PARTS

REQUIRED PARTS

Basically
the perfect diameter with the exception of the deformation caused by the
holes in the pin. A little minor file-work and a spin in the drill with
some very fine sandpaper makes them drop in replacements for the front
and rear take down pins. I also chopped mine and cut them down to the
right length with my Proxxon Mini-Lathe but that is optional extra credit type work and not required.
Although
duct taping a magazine in place would have certainly worked, I took just a
bit more elegant approach which required only a tad of fabrication. I
used a 3/16”x1.5” bolt with two nuts to hold a latch I made from ⅛”
aluminum scrape I had in the shop. You could screw it down as a
permanent fixed magazine or loosen it up and add a 1.25”Lx1/4”w wide
spring to provide full function capabilities which functions just like to real deal. I was
actually pretty proud of this little part when I was done as it worked
perfectly on both the .22LR Black Dog and .223 Troy mags tested.

FUNCTIONING
A
testament to the AR design, 300-rounds downrange of .22LR and I did not
have one issue aside from a few issues with the ATI upper I have come
to expect. Even after a swapping out the dowel rod stock
for a real buffer tube assembly, I had no issues at all, with the
exception that the bolt does not hold back after the last shot, a little
hot gas pops out of the bolt latch void, and you need to be darn sure
that “safe” means properly clearing the weapon. Amazingly, only a couple of bucks of hardware parts can put an AR into commission as a reliable and operable AR... but it will not win any beauty awards. In the end you only have to have a complete buffer tube and trigger assembly to make an AR work with only parts from the hardware store.
FINAL THOUGHTS
This
was a fun experiment that demonstrated how versatile durable
and field serviceable the AR15 can be. With the exception of the cost of
the JP Trigger, and buffer assembly, and broken Mako buttstock, the lower parts cost from the
hardware store was less than $5 to deliver a .223 capable AR. If you can find a dedicated .22LR upper or a drop in .22LR conversion kit, a complete buffer tube assembly is not even needed.
The kicker to this entire story was
that I found my AR lower parts kit shipment on my front doorstep the day
after I tested this hacked together AR... I guess I didn’t have to wait
that long after all.

This sounds like a great tutorial on how to keep an AR15 banging away in a post-SHTF scenario when there's zero access to all of those pricey, tiny & specialized parts.
