20" AR15A4 Home Defense?

[mark5pt56]

Completely unusable, too heavy, not free floated, has a big ugly front sight thingy and isn't painted. And I think it has a useless A2 flash maker, what's wrong with you?

I just put this together a couple of months ago with the Colt 20" I recently stole.

Thanks for the pics, all. I'll try to get one up when I get back from work.

Namely - handguns, especially one which incorporates a visible light or laser, and chambered between 9mm to 45 auto.

When you say "between" 9mm to 45 auto, is 9mm included in that list of acceptability?
Also, yeah, if I really had to go clearing rooms and such, I'd probably opt for my Glock 19 or Glock 21 over either a 20" or 16" AR15. Therefore, there really is no niche for the carbine ARs for me. Folks seem to think that the carbine length is vastly inferior to midlength ARs for reliability, and I've had some concern about that myself. So I figured I may as well go for maximum reliability and get the rifle length system.

Very true. It's also the same length or shorter with the stock collapsed as the M1 Carbine.

Think I'm gonna throw a red dot and sling on it and start keeping it as my HD gun. Wonder how it'd be in classes.

Unless you're doing vehicle stuff it'll be great. A 20", especially with the adjustable stock is not difficult to use.

It's a poor choice vs a carbine in any type of constricted environment, same as the shotguns mentioned above. It's still better than nothing and not bad enough to worry or obsess over.

Your concern over carbine reliability is overblown, and sight radius talk can't be taken very seriously since the RDS became common and tough. These are arguments that may have been relevant in 2001, but are not in 2018.

If you have taken classes but have not been through a shoot house I recommend it.

It's only 4 inches longer than a standard 16 inch carbine. Tactics, shot placement, and luck will matter far more than an extra 4 inches of barrel in a gunfight.

When you consider that most, "16 inch," barrels are actually 16.125-16.25 inches long, it's actually less than 4 inches. (Not hugely shorter, but still shorter.)

I say run it. Unless you have kids or other family members in other rooms that you would need to move to in a home invasion to protect, I'd rock an A1/A2/A4 with or without an A5 stock without a worry.

Post a picture of your A4 with A5 stock! That's how it should have been from the start.

Amen to that!!

I hope your new years resolution is to post more often.

I've even gone to the RDS for home defense.... and I'm the biggest irons advocate ever.

What ever happened to the Markm we knew and loved? The one who called people gay for having FF rails?!?!?! We want him back!!

Your concern over carbine reliability is overblown

It seems like many on here consider midlength gas systems to be a minimum for a dependable rifle. I'd like to believe it's overblown, but I do have doubts based on the CRANE test showing that midlengths do have a higher Mean Rounds Between Stoppages than the carbine length. Part of the reason I bought the AR15A4 was to sidestep the carbine vs. midlength altogether and go right to what is supposedly the most reliable of all the gas systems.
