Useful Info: Making Use of the MOLLE Bandoleer

I ran across this piece from Defensive Concepts North Carolina, and feel it's worth passing on.

Making Use of the MOLLE Bandoleer

In the current widespread unrest, in which AntiFa is threatening to come out from the cities to the 'burbs, it behooves you to have a defensive rifle and supporting accoutrements. A bandoleer is an inexpensive means of having a grab-and-go supply of reloads at low cost. Even if you're setup with a full plate carrier, a bandoleer would be useful to go along with hand-outs, if that's something you maintain.

7.62x39 AR-15

Today I finished building my first AR-15 that isn't chambered for 5.56x45mm. It was time for something different.

While I find the 6.5 Grendel to be very interesting, I didn't want to get into a new caliber at this time, so this one is in 7.62x39. I've maintained a good stash of that caliber since before I got into ARs, starting when I bought a Chinese SKS in 1988.

I used the following parts:


The enhanced firing pin is to improve reliability with foreign ammo with hard primers, while the bolt from BRA is supposedly higher quality. One thing 7.62x39 ARs have the reputation for is breaking bolts. I'm hoping to avoid that but in case it happens, I'll have a spare ready to go.

First impressions of the AR-STONER kit were good, except for the poor staking of the carrier key to the bolt carrier, so I restaked the screws.

Here's the assembled carbine on my messy workbench:




And a close up of the receiver. It's my first AR with a graphic on it:



I would have finished it last weekend but managed to shoot a detent spring into the unknown. To complete the rifle I had to wait for an order containing spare detents and springs to arrive from Brownells.

It will be interesting to see what the recoil impulse of an AR-15 in 7.62x39 feels like compared with an SKS, AK, or VZ-2008.

I really hope that eventually Pennsylvania will legalize semiauto rifles for big game hunting. We got semiautos legalized for small game and varmints so hopefully after another year or two the PA Game Commission will realize that it hasn't caused the sky to fall and they'll let us use them for deer. This would make a fine rifle for the ranges encountered in most of PA.




I should be able to put a few rounds through it tomorrow, after which I'll post a follow up report.

Choosing an AR-15

The following query was posted to a mailing list I'm on:

Am thinking about purchasing an AR15 but there are many different
models. Which do you recommend for both home protection and emergency
hunting? I would definitely want one that chambered both .223 and
5.56.

Also what is the best scope for both quick target aquisition and very
precise (1 or 2 inches) shots out to say 150 yards? Would a zoom be
best? Also do they make a good scope that is also night vision?


And this is what I posted in reply:

I recommend going over to AR15.com and perusing the technical forums,
along with the various tech manuals they have onsite.

In general, when looking for an AR15 to be used for defense I regard
the following features as requirements:

1. 5.56mm chamber. This improves reliability and allows you to shoot .
223 or 5.56 spec loads safely.
2. Chrome lined bore and chamber. Improves reliability and makes it
easier to clean.
3. Flat top upper receiver, which greatly simplifies adding optics.
4. Properly staked bolt carrier. Loose carrier keys contribute to
functioning problems.
5. Barrel twist of 1:9 is fine but 1:7 is better, because it will
handle heavier bullets.
6. A lightweight or M4 profile barrel is better than a heavy barrel on
a defensive rifle. HBARs are fine for target shooting but slow you
down for defensive work.
7. No match triggers on serious rifles. They aren't rugged enough.
8. Avoid the temptation to hang all sorts of tacticrap off your rifle.
9. I like having a telescoping stock. Aside from making the rifle
more compact for storage, it enables me to adjust length of pull for
different clothing (e.g., t-shirt vs. winter coat) or different
shooters.

My rifle is a Colt AR-15A3 Tactical Carbine. The one feature I may
change on it is the barrel, it's a 1:9 twist HBAR. I'd prefer a
lightweight 1:7 twist barrel. Based on what I've read by instructors
who see lots of ammo go downrange, Colts tend to be the most reliable
of the major manufacturers. You pay a premium but on a defensive
rifle reliability is the single most important factor.

I've added a DPMS ambidextrous safety because I am left handed.

Unless you are running a suppressor or a short barreled rifle, a gas
piston upper is unnecessary. Learn to properly clean and lube your
rifle and it'll be reliable. (Hint: run it wet.)

For civilian defensive use the best choice for an optic is probably an
Aimpoint, non-magnified red dot. The Aimpoints offer very long
battery life, are very rugged, and fast. I have an IOR Valdada 3x25mm
CQB scope, which offers low magnification (important for me because if
I lose my glasses I'll at least have the scope) and is built like a
tank. I bought the IOR as a less expensive alternative to a Trijicon
ACOG.

I would avoid a zoom optic on a defensive carbine unless the highest
power is 4x. Murphy's Law dictates that when you need to use the
rifle up close the scope will be zoomed to the highest magnification,
which will slow you down. Illuminated reticles are a good, so you can
see them in poor light.

Stick with USGI milspec aluminum magazines or Magpul P-Mags. The
British and Singaporean steel mags are good, too, but may benefit from
replacement springs and/or followrs. HK mags are good but grossly
overpriced. Avoid no-name or USA-brand magazines, which are junk.
