If you were going to build a defense AR-15, with the best of everything, what parts?

Instead of buying a P90 as a christmas present to myself this year, I'm going to build something more practical -- another AR. My current AR is just a base Sabre Defense M4.

I'm not a world class shooter, so I don't necessarily need sub MOA groups and the like. What I'd like to build is a 16" or 18" barrel AR, carbine or mid length gas system, with the highest quality, most durable components out there.

I've never looked into building an AR before, so I don't really know who to go with for the various parts.

Thoughts?

(oh, one caveat, none of this piston crap. DI works fine, and the piston systems make the rifle heavier. if i wanted a high quality piston rifle, I'd buy a SCAR and be done with it).
 
1. acquire cheap lower that is still milspec(they are all the same really)
2. acquire nice barrel
3. acquire nice stripped upper(any good one) and rest of parts
4. ???
5. PROFIT?

You dont need a "elite tacticool" rifle and throw out MOA.
 
If it were me, I would spend that much money on ammo and go take my AR out and shoot, shoot, shoot!

You will get really good with your existing gun, if you give it a chance!
 
NiB BCGs seem to be the flavor of the month. NiB coatings are quite impressive, and should add to the durability of a rifle. Otherwise, what the other folks said - buy a bunch of ammo. Any gun is only really as useful as the amount of ammo you have for it, and any rifle is only as good as the shooter.
 
This may not be what you want to hear but I wouldn't build an AR for SHTF. I'd build an AK because I'd be less concerned about MOA accuracy than just being tough-as-nails reliable.

I have an AK 47 and 74. I think the reliability difference between AR's and AK's is overblown... and AK's aren't modular like an AR. Good luck scavenging parts from a WASR to fix a Tantal. On the other hand, your chances of scavenging parts from one AR to fix another are excellent.

I think an AR plus a choice selection of repair parts is probably a better SHTF rifle than an AK.
 
Why build one when you already have a darn good one in the Sabre Def?

Besides, you may end up overlooking something in the build and lose some of the higher reliability you were trying to achieve.

Jeeze, the guy asks a reasonable question and there's already replies about how an AK would be more reliable after planet nibru collides with the earth and armegedon is upon us?

Too funny.

Harmon - check out the CHF barrels from Noveske (and Palmetto State now, as well, I hear). BCM or Colt BCG. BCM gunfighter charging handle maybe?

I know it's a decent rifle, but I'm pretty sure it's not the best of everything, like I'm looking for. Why? For the hell of it, and because I want one, that's why. I don't think the zombies are coming (any time soon anyway ;)), and I don't think were facing a global collapse of society like in the book Patriots.
 
According to the enthusiast forums, Colt is the gold standard for AR rifles.

If you're looking for a particular vendor to buy from, the popular "top tier" vendors are Bravo Company (BCM), Daniel Defense, LMT, and Noveske.
 
Didn't sabre def. go out of business? I thought they got charged with breaking several import and export laws and had to declare bankruptcy... There website doesn't work.
 
good grief you guys. at least try to answer the question.

i honestly don't think you can build a better gun with higher quality more durable parts than the KAC SR15.

however, i'd look at some of the following:

JP bolt made from better steel than milspec (e.g. BCM) http://www.jprifles.com/1.4.7_bc.php#1, though i'd put it in a BCM carrier.

Noveske barrel with the double-thick chrome
magpul UBR stock
geissele SSA-E trigger

Vltor MUR upper with a DD lite rail, or the vltor 1-piece upper with rail

more later... wife is calling :)
 
Each to his own with the best of anything. Especially AR parts. I think that all the parts are made in one big factory.(probably some place like Olympic or DPMS) and sold throughout the market. So what are you really getting anyway?

In this market I do not believe you can buy quality or reliability. I think you are just trying to buy better luck than the guy on the other side.



Your money, spend it as you will. Maybe the P-90 aint such a bad idea any way.

I built one for the same reason that you want to build one. I won't go through all the thought processes that went into this but here is what I ended up with.

1. Double Star stripped lower receiver. Good, high quality mil-spec lower made of 7075 T6 aluminum.
2. DPMS lower parts kit. Many lower parts kit on the market. Again, just make sure the parts are all mil-spec.
3. BCM 16" standard mid-length upper, complete. I went with a complete upper because I did not want to purchase tools required to assemble an upper that I would most likely use only once. Plus, this upper had every single feature that I wanted. To this upper, I added a BCM M16 Auto Bolt Carrier Group, mil-spec M4 6-position stock, buffer tube and spring, Cavalry Arms mid-length hand guard, and MagPul trigger guard.

BCM and Colt are two manufacturers that meet or exceed every single military specification.

I have been very happy with the end result. Not lots of rounds through the gun, about 1k, but have had zero problems of any kind. IIRC, about $950 total in the gun.

AR build

Smith and Wesson VTAC with a Leupold Scope and lots of mags and ammo. How much is your life worth to you my friend? mine is priceless only the best will do for when the SHTF, Nuff said.
 
Is there any particular reason why you are insisting on building it yourself? I'm just asking because the only real advantage to building it yourself is that you get to choose the parts that you prefer to use. If you just want a good rifle, there are many to choose from.

In any case, if I were to build a rifle with what I thought were the best parts (or some of the best parts) I'd go with Daniel Defense receivers, DD or BCM bolt/carrier group, Magpul stock, DD or Noveske barrel and either DD or Larue handguards for free float or Magpul for something more conventional.

Parts from an AK 47 wont match parts from an AK 74, but using this example you can also say that parts from an AR-10 wont fit an AR-15. Anything can happen, however, I have never had a part break or need to be replaced on any of my AKs.

But, getting back to the subject, as stated before the only real advantage to building an AR, is that you end up with exactly the rifle you want plus there is a lot of satisfaction in putting your own rifle together. If you start out with high quality parts, you will end up with a high quality AR. I've been real happy with everything I've gotten from BCM and their CS is top notch.

What parts might be in it for the extreme use are already out there - it's called milspec, a minimum standard to protect the taxpayer and soldier, which provides a floor of reliability that will endure 5-10,000 rounds. You will never shoot that much, and likely won't survive carrying 500.

Bluntly, no one person will be guaranteed any life expectancy after 30 days. If it's really really SHTF, then there will be little food by then. Water, good luck, after three days you will need to purify every drop, you cannot carry enough of it.

So many of the gun threads totally ignore the logistics of survival - where are you going to get the majority of your basic needs? Water, food, shelter? You can't run and gun enough from one source to another without confronting numerous other people equally concerned about maintaining possession of their meager supply.

What gun you have or use will only take disposable income away from being able to maintain a potable source of water. Frankly, you'd be better off with a water collection system that can hold enough to ride through a dry summer, and a purification method that needs no arcane or hard to find chemical. Rainwater collection and a drum of bleach will be a better investment than ion treated parts. A loading press and brass catcher will do more than expecting to pick up ammo off the dead. No guarantee it won't be .30-30 - America's most popular cartridge.

Just leave it at iron sights, or a simple 2x, if it needs batteries, they will all eventually be used up. Remember, it's SHTF, the factories are all shut down, no transport, no stores, nada. Give that more than a few years, no socks or underwear, either. Your last battery might be used up as you listen to the final radio station sign off in a hail of gunfire.

Complete political collapse would be a picnic, just stand in an area clear cut by an EF5 and see nothing usable as far as the eye can see, then think SHTF. If the infrastructure really goes down, there won't be firefighting, entire suburbs and cities will burn to the ground - set to the torch by looters, opportunists, or those who lash out and want everyone to suffer equally. Natural fires from storms will sweep uncontrolled county wide, just like they used to do.

A working .30-30 lever will be the SHTF gun, it's the one cartridge that can be found nearly everywhere. 5.56 will be hoarded, only .Gov issued after the stores close, and resistance to the Authority Exercising Jurisdiction will be put down severely. Open carry of any military weapon could be met with Shoot on Sight.

That wonderful fantasy gun now the pride and joy of the local District Chief. Stray dogs being fattened for slaughter cracking your bones.

SHTF indeed. Childrens game. Lets start talking Apocalypse, now that's a disaster.

Entirely why these threads are entirely worthless. A gun will be the least useful answer. Clean water, some food, a place to stay warm, and a simple knife are what our ancestors prized in the day. Not having the skills to obtain the first three will kill more people in thirty days than not having a gun.

Focusing on firearms as the solution will create more zombies than survivors.

Stock, pistol grip, handguards, dust cover, recoil spring...I think that there are a few more that are interchangeable from a 74 to a 47.

yes, because this is a gun forum, not a survival forum.

and if this thread is going to remain open, it will continue to discuss firearms, not water supplies, political collapse, etc

^ This.

The only problem may be that the SR-15 uses proprietary parts. Those proprietary parts are real improvements however, and they are designed for a minimum of 20,000 rounds. For hypothesis sake let's pretend that I could actually find those thousands of rounds and manage to wear out the barrel or the bolt of my SR-15. Not a real big problem as the SR-15 upper is like any other AR upper and will fit with any in-spec AR lower. Problem solved. Swap out the worn out SR-15 upper with the spare Noveske Light Recce in my safe and I'm back in business.
 
^ Why not just use the Noveske barrel from the get-go? Don't they use M249 barrel blanks? Double-chrome lined and the best possible barrel steel. I think that in a semi-auto AR-15 it would the the proverbial cockroach. Long after you and I are gone, it'll still be around.
