Which AR-15 Barrel Length: 16, 18, or 20″?

I give this: you won't be at port arms in your hallway at 3 am when there is a bump downstairs. Just have a rifle is top priority, everything else is secondary.

I’m glad to finally find someone who agrees with me on the 16 or even 14.5” Minimum barrel long on the ARs…..

aged like a fine wine. Thanks for the info!

Military test for a 16 inch barrel is 600 meters=656 yards. So definitely doable. As well as this being a 7 year old video. Pistols can do what you were saying is the 16 inch stats

Awesome review/breakdown. Helped me make my own purchase. 👍🏻

a minimum of 16 for self defense? 10.3 works just fine within 50 yards

13.9

useless video without chronograph readings

Unless you’re aircrew, ride in tracks, or kick in doors for a living, there’s no fucking reason whatsoever for anything less than 20 inches of barrel.

20" is my fave too. 5.56 is very velocity dependent. 🇺🇸 👍

Congratulations on the 200K Reid. You've earned it.

You're a good guy reid

These guns are for offence outdoors not in doors this man is a complete dumb ass

My God new gun owners these people are complete idiot's for God sake don't use a rifle for home defense unless you trying the people that live behind what you are shooting at these fool's are the main reason for all of the children getting killed in there homes listening to fools like this

I didn't know Chris pontius was into guns

Lovely view of someone's carpet. I'll give it a miss next time.

14.5 or 14.7 that's been pin/weld to 16" with a lightweight chf barrel with a good handguard from Midwest industries or SOLGW with a RELIABLE and REPUTABLE BCG from SOLGW or BCM…. When it comes to the lower you can REALLY save some money. As long as you have a reliable lower parts kit you can save a boat load of money. If you HAVE to spend money on a complete lower then there's nothing wrong with PSA but I wouldn't spend any more than an Aero lower. What's great about putting together your own lower is that you can save ALOT of money on the furniture if you put it on yourself. Imo the best furniture out there BY FAR is made by bcm for both stock and pistol grip. Stay away from gimmicky BAD levers or 45° safety selector and honestly stay away from ambidextrous controls period. Oh yea, almost forgot one of the most important parts…. STAY AWAY from carbine length gas system and go with midlength!

By any chance does anyone know what handrail is used on the 18" one?

nothing like the 20 inch for accuracy.

Saw you dancing! Loved it! 🕺🏻

20 inch for the win!

Longer barrels are better for hunting & shooting long range. Even though I prefer the shorter barrel but I would NEVER buy a pistol AR-15 nor AR-10. I prefer the mid length 18 inch.

Meh, doesn't really matter with a .22 caliber pea shooter imo. I shot consecutive experts with both the M16A2 and the M4 during my career. If I was looking distance I dump any of my AR15s and go to my QD10 in the .308 win.

20" hands down. If I need a short barrel, I'll use a handgun.

The velocity of a 55 gr M193 on a 16" barrel is 3132 fps, the 20" barrel is 3259. So its 127 fps for that 4" difference, which makes it 63.5 fps

Most home defense situations in my metropolitan area is probably within 50 yards, anything beyond that is could be questionable in the eyes of the law. Ask the roof top Koreans. Something smaller and lighter is better for me.

Thoughts on PDW AR weapons??

I was thinking f*** I'd hate to be his neighbor if he lived in a condo… For indoors I used to go with the 12 gauge.. oo buck with a slug behind it.. I usually try not to shoot indoors

I mean CAG and DEVGRU are schwacking dudes with 10.3 on up. My favorite shooter is an 18 with rifle gas though.
