Advice for starting an AR-10 build?

Post by Iunnrais »

So went out this weekend with some friends to go after the hogs that have been tearing up the family farm. Took my nice new 1895 in .45-70. Man was I using the wrong tool for the job. Oh, I'm certain that had a hog actually gotten close enough for me to reliably hit that it would have done the job. But when folks are using .308, .270 and .30-06 rifles across long stretches of fields, it just falls a bit short... Should be much better for deer up in NE Texas with my cousins. Trees kinda limit the range there.

So time for a new project where I can spread the expense across several months and build a new rifle that can actually work for the job at hand. This spreading part is kinda key as it will help keep my hide intact compared to plopping down another large lump sum. :biggrinjester:

Any suggestions from the gallery on a good starting point?

Before you buy anything, I reccomend you poke around this site's forum 308ar.com

I've found the best information there. The most important thing you must realize if you are going to do what you say is that uppers & lowers are not standardized as AR15's are. IOW, for the most part a DPMS lower doesn't match up with an Armalite upper. Also they dont all take the same type magazine. There are several parts that are interchangeable with AR15 such as triggers (again for the most part).

I started with a basic DPMS model and tweaked it here and there. It takes standard Pmags btw. It's an incredible weapon IMO. Things I recommend to upgrade from the base line... muzzle break, trigger & buffer/spring. That site has good reccomendations as well as a buy & sell section that would suit you well to piece one together.

Thanks. I think that I'm going to be in information overload from that site. :)

The DPMS versions are far more flexible IMO. I had an Armalite AR10 but had problems getting any kind of aftermarket parts, and traded for an LR308 in frustration. The DPMS platform is also supported by a number of other makers and as such, magazines, quad rails etc etc are alot easier to find.

My 2¢:

Unless you are aiming to build a target rifle, avoid stuff like heavy barrels, Magpul PRS stocks, full length rail systems, etc. Now, here's why.... I actually own an AR10 that is heavily customized for target/SASS work, and it weighs an absolute ton. All up, with the scope and bipod mounted, it weighs 17 lb. Even in carbine configuration, the AR10 is a 9 lb rifle, and that is a lot of gun to tote around if you're like me and likely to tire easily.

Word of caution before you spend too much money.

+1 what TAM said.
This isn't a rifle you want to hang allot of accesories onto.
I've got the 16" w/ plain OEM free float hand guard + magpul AFG & TLR1 light and it's no lightweight.

I would add that the DPMS 16" barrel is more accurate for longer shots than you would expect for a carbine.

The newer versions of the Ruger Gunsite Scout have an 18" barrel instead of a 16.75" barrel like mine. That extra 1.25" translates to extra velocity at almost no additional weight penalty. The one with the shorter barrel weighs 7 lb. With an 18" barrel, they weigh 7.1 lb. The gun comes with a steel 10 round removable box magazine made by Accuracy International. Ruger sells polymer replacement magazines in 3, 5, and 10 round configurations on their Shop Ruger website, which are cheaper than the steel mags and more compact. Here's a previous post of mine about the magazines: viewtopic.php?p=731214#p731214" onclick="window.open(this.href);return false;.

I can't speak to current rifle prices with all the panic buying, but I bought mine in early November, 2012, and I paid $757.00 for the rifle. A SWFA exclusive Leupold 1.5-5X33mm VX-R Firedot Scout Scope was another $600.00. So for a combined $1,400 or so (rings included), I had a compact lightweight .308 rifle with a larger capacity and a very good scout optic mounted.

This is just my opinion, but this this combination of rifle/scope is the perfect hog gun if you're going to be hunting from the ground. True, a semiauto might be better, but show me a 7 lb semiauto .308 that's available to mere mortals at mere mortal prices. Even a plain jane short barreled M1A weighs 8.5 lb. If you're hunting from a stand, any .308 rifle will do as long as you can carry it to the stand. I have another .308 bolt rifle that has a much longer barrel (and is consequently a lot heavier) and will develop more velocity and is far more accurate if I were going to hunt from a stand, but if you're hunting on foot and your shots are all going to be inside of 350 yards or so, I think you would be very hard put to find a better hog gun at an affordable price than the Ruger Gunsite Scout.

Thanks for the advice. One of the guys with us had a Ruger Gunsite scout. Neat rifle indeed and I wouldn't mind having one.

My 1850 with scope, light, sling and ammo clocks in at 10.25lbs. Hauled that all over creation this weekend.

Those 3 accessories are pretty much my requirement for stuff hanging off (although a bipod/shooting stick would have been handy in a couple of places). Though I was really over scoped for the task. A 3-9 would have served me just as well as the monster that I had on (8.5-25 that I robbed from my .22 plinker).

Agree on the dpms if for no other reason than the pmags. Biggest issue so far seems to be availability. Knew that I should have picked up a lower last year ;)

It won't be match accuracy, but it will certainly be good practical accuracy, which is a degree of precision that I think a lot of people tend to overlook because everybody wants to be Bob Lee Swagger. To put a finer point on it, if you were sniping at someone 1,000 yards away, a .308 Winchester bullet of heavy enough weight is going to kill that person deader than a doornail whether you hit him in the chest or the head........and the chest is an easier target. So anything with decent practical accuracy at 300-400 yards is going to be more than adequate. And, given any two barrels identical in all respects except length, the shorter barrel will likely be more accurate because of the amplitude of the barrel harmonics. The primary issue with 16" barrels is bullet velocity and terminal performance. The bullet has to be going fast enough to upset/expand properly on impact. Getting it out the barrel fast enough to be effect at 300-400 yards is pretty easy. Getting it out the barrel to be effective at 1,000 yards might be more problematic. It will travel that far, but will it be going fast enough at that distance.

Fortunately, none of this really matters when you're hog hunting.

Nope. 400-500 yards would be the max out there and to be honest, likely out of my current personal effective range. ;)

If I load up a 300gr in the 1895 to 2200-2300 fps, I can extend the lever's max out a bit at the cost of some nasty recoil. Personally, I kinda like the .243 option in the ar-10. Light recoil for fast follow up shots without having to move my hand to manually cycle a bolt. Nice flat trajectory. Easily available ammo.

Doesn't need to be a $4k target package. I just need minute of pig accuracy on the far side of a wheat/peanut field.

Or maybe just a good range finder and an artillery computer ;)

Go right ahead :)

One thing that I've not really considered is wether or not perhaps an ar-15 might work just as well in something like 6.8spc. It's just not something with which I've had much experience. Especially as I will likely hand load for it at some point (mainly a materials issue....primer/powder etc)

Just so many options now that I've started looking... Kinda boggles the mind in a good way.
