AR15 advice

1.75 MOA dot on the Trijicon SRS, but looks larger due to the mirroring. $1,000 at opticsplanet.com

Talk shit about a red dot yet you run one ?
 
So much lol on this thread. The youtube guy spent one "tour" (three weeks) as a contractor guarding a latrine. Completely devoid of any skill or knowledge. Has never discharged his weapon on duty as a cop and was fired after a short time on the job. He has never served in the military.

AR's are a shit home defense weapon. Over-penetration is a huge concern inside a home, unless you live in a concrete bunker. Frangible bullets--but then you're better off with a .45. A Glock 21 or preferably a HK45 or HK45C. A carbine in a pistol cartridge is ideal, but that Hi-Point is not known for reliability.

A rail-mounted flashlight so that you can distinguish between friend or foe. Lasers are retarded. Minimal utility as a deterrent--and would you want to be in a situation in which you're praying that the intruder will be scared-off if you put a dot on his chest? lol to head-shots. You are summarily f*cked if the guy has is motivated and wearing III-A body armor. You're trying not to piss yourself as the dot is wavering three feet off-target.

ARs are defined by their operating system; either DI (direct-impingement) or piston. The M16/M4 are DI guns. The gas acts directly on the BCG, thereby cycling the weapon. In a piston gun the gas acts upon an op-rod which impacts the BCG to cycle the weapon. The piston gun can be run dry (minimal lube on BCG). The DI guns should be run wet due to fouling inside the receiver from the gas tube.

The Steyr AUG is a piston gun (NOT an AR) with an OAL of 28". Much shorter than any AR, including any of the carbine-variants. It's a very clean running weapon and is considered state of the art. The bolt rides on two rods within the receiver. Steyr ran >16K rounds through the gun in a few hours time.

Go with a piston AR if you must have an AR-platform. PWS, LWRC, HK, etc. The HK MR556 is the best of the piston guns. There is another piston maker that I cannot recall at the moment. They are a govt-contractor who makes ARs for the civilian market as well. KAC for a DI gun. Tsing Tao has a FN SCAR Heavy in 7.62, but they lake a "light" version in 5.56 as well (.223). Excellent weapon. A good AR piston gun runs from $1500-$3000. The KAC DI is $2500. The AUG as outfitted is around $3000.

AR with self-defense loads (Corbon) or preferably frangibles. I have two AUGs inside the home and two .45 pistols. One of the AUGs has a 9mm conversion and it is my go-to home defense weapon. The other AUG mags are loaded with Ballisticlean .223. A Surefire X300 Ultra rail-light and a Trijicon SRS RDS set on the lowest (visible) output. Keep the house dark and both eyes open when practicing with snap-caps inside the home.

Awesome post.

I have the SCAR as mentioned, but also the LWRC REPR (20 inch barrel) and an H+K mr556, agree with your recommendation on those as well. Though you do pay for it.

For home defense, I use sig P226 (.40) with hollow points in hopes it will limit penetration a bit more. However, nothing prevents collateral damage like training.

I didn't see him talking shit about owning one.

The one thing I agree most with in your comments is the aspect of adrenaline affecting your shot. This is why you train with 1000s of repetitions - so when you need to go live, it's far more natural. Slow is smooth, smooth is fast.
 
I am not a fan of the AR15. I live in a rural area with lots of trees and brush and the 5.56/.223 round is not very effective in this environment. The .308 which I favor has a bullet weight that is almost three times that of the .223. It delivers more foot pounds of energy to the target at ANY range and is effective up to 1000yrds. I keep all my M1a rifles in the gun safe though. For home defense I just keep a cheap Mossberg 500 next to my desk and four dogs out in the fenced yard around my house. Nobody approaches without the dogs warning me.


I have a PSG-1 with the Hensoldt, and indeed it's a fantastic caliber, but I never shoot it. I keep a few hundred rounds on hand. 5.56 is flat shooting out to 100, but what can you do with a 22-projectile? .220 Swift would probably have a lot of knock-down power! ;) There is no substitute for triple the mass (average 308/223 as you state).

7.62x51 retains more that 3x the energy at 200Y. BD is close, however. 3" for the 7.62 and 4" for the 5.56. Ballistically (Ito), they are pretty close, but you're talking about a 62gr projectile.

Non-lethal ballistics are insane. Going for portability over lethality.

Thanks Destriero. The main reason I picked an AR15 was due to its amazing popularity. This makes lots of competition in the market place, lower prices, a quality/price curve with plenty of data points, lots of aftermarket and plenty of parts. Also, it will be harder for the feds to outlaw and it scares girly men :D . I want some sort of rifle that I can be lethal to about 250 yards along with a reasonable rate of fire and capacity. I know how regular DI works. A piston seems like new tech that is heavier and more expensive. But I didn't know about the oil part so I will read up on it.

I'd be interested in hearing anything else you'd care to say about AR15s and rifles in general.

DI guns are generally more accurate if the barrel is free-floating, but that is a minor-issue. Just keep the bolt a bit wet with Militec or Frog Lube. Piston actions have been around for over 70 years, but Stoner chose a less complex action. The AK is a piston rifle, and the most widely-adopted small arm in history.

Moly Disulfide (MOS2 by LiquiMoly) is probably the best to coat the BCG, but the stuff stains everything and is black as owl-sh*t. There are some good penetrating lubes, so i will check MidwayUSA and get back to the thread with recommendations. Certainly you can get by with simply coating the BCG with Frog Lube and cleaning after each range outing.

I like ARs but am not a fan of the ergos. My 9mm AUG is 25" OAL AND 31" with the 100% Inconel suppressor. I don't suppress 223 or 762, only pistol cals and 300BLK. The action of the bolt is louder than the muzzle report when running subsonic ammo. I consider the AUG the most reliable semi-auto outside of the AK platform.
 
Destriero, have you ever owned/shot an AK74? Been looking into them and there are lots of plusses -- simplicity of design, solid reliability of the AK platform, lighter weight and less recoil than a 47, about the same terminal effects as 556, decent prices around the lower range of AR's. I know with the 7N6 ban ammo might be a little tougher to find ie, none sold at Wally World. Anyway, was wondering what your experience is and if there are other positives/negatives that you can think of.
 
Yeah Magna, the 74s are great. I had a Norinco (Navy Arms import) for years. Anything with a chrome-lined barrel is going to be worth the money. They all shoot; it's whether you want to pay for better accuracy. Make sure the folders fit your shoulder. You can get polymer-coated steel-case for under $0.30 a round.

I know you didn't ask me, but there are plenty of places online to obtain that ammo for relatively little cost.
