I built this AR-15 on a Pac West Arms (PWA) Pre-Ban
lower which was registered as a Short Barreled Rifle (SBR). The
upper consists of a Model 1 Sales 7.5" pistol kit, while the stock is
a standard 4 Pos. stock. You can see that the handguards are
wrapped with Para Cord. That is necessary because if the heat that
little bugger generates after just 2 quickly fired magazines. After a
few Beta mags the gun can become too hot
to hold, even the plastic pistol grip (far away from the action) gets
WAY too hot. That is usually when I'll just dissemble the gun
and let it cool. That usually take the same amount of time it takes to
load 3 more 30-rd mags (by hand, I don't "DO" stripper clips) or a
The only problem that I have encountered was a fail to
Eject. I won't tell anybody exactly how I fixed the problem but
I will say that you will need a SERIOUSLY strong extractor spring
(Which BTW I am not using).
When I travel wit the Micro-Car, I keep it broken down
in a Laptop PC case that I found. It is the perfect cast. Its a soft
case that has enough room for the gun with a magazine inserted, and
pockets that hold 2 more magazines, plus a place to keep a copy of my
Form 1, and two pockets where I keep targets, the 22, conversion kit,
other Flash hiders, sticker Dots (to cover up old bullet holes)
thumbtacks, ear plugs, safety glasses, a yellow "chamber empty" plug,
I call it a Micro-Car using the same idea as the UZI
family of rifles, the larger just being the UZI rifle, and then the
mini UZI and micro UZI.
