Bigger AR type rifle

[demontang]

Size and weight drive me away from the AR10 when you can get an ar15 in rounds that are just as good or better then what is in the ar10 I figure why pack around the extra weight when I dont have to cause an ar15 can be plenty have after a day of hunting. But everyone likes different things

What 'rounds' can the 15 have that are as good or better? I have an AR15 lower, I just want something deer legal

6.8 spc and several short magnums or supershort magnums.

.450 bushmaster and .458 socom.

I would not say there are better rounds for the ar15 compared to the ar10.  There are some rounds that are good or equal up to 200yds for deer that are stated above but anything larger than deer outside 200 yards there really isn't a round capable in the ar15 in my mind.

It really is up to what you want to do with the gun.  I think you can setup a nice deer rifle in the ar15 and possibly a good brush gun for larger game if you were only going to take 200 yards or less (200yds is pushing it with the large ar15 calibers)  Anything over 200 yards on larger game you would have to go to the ar10.

Unless you get one of those crazy uppers that come with a magwell on the side so you bypass the lowers magwell. They're pretty spendy though and I don't even know how well they work.

AR-15 for deer, legal in Washington with decent ammo availability and no need for a long heavy barrel I would go 6.8spc. I bet you would be happy with a 6.8 upper from Bison Armory and it won't break the bank. The 6.8 is not as good as the AR10 cartridges but will easliy kill deer at moderate ranges. There is alot of info at www.68forums.com

thanks, Ill research a little more, I dont know anyone with a 6.8 anything, from the little Ive researched they seem like a really slow round ( 2500fps ish ), but Ill keep reading

6.5 Grendel and the 300 blackout are other options.  I think if I was building an AR15 just for deer it would probably be the 6.5.  Personally I am looking at getting a AR10 for bears and elk where a quick follow up is a big benefit.  They are heavier but that just means I need to get in better shape.   I also just like the rifles so really just getting it to have it.  The reasoning above is for the wife!!

The 6.5 Grendel walks all over the above mentioned out to 600 yards, when it comes to taking game and proven accuracy and it's a conversion that only needs a bolt, barrel and magazine. With the acception of the 6.8 spc. The rest need considerable machine work to the upper receiver/ejection port. Also match grade Hornady 123gr A-max loads are available everywhere. Great for deer, chucks and yotes .$21.00 a box, all the 6.5 Grendel barrels I have shot , grouped them very well.

For several years I purchased Grendel ammo from the link bellow, I could never get a hand load to groups as tight as their 120gr Ballistic tip load. It took my awhile at the bench to get the right hand load combo. They have a large selection of Grendel ammo. While the 120-123gr Gendel load does not have the energy of a .308 at extended distances it does overtake the .308 168gr at 600 yards and beond less windrift and drop. My brother shot a Mulie with his Grendel/16" AA M4 carbine barrel and a 120 Ballistic tip at 493 yards, killed it clean(Double lung) through and through, we never recovered the bullet.

I have had people argue that it wasnt enough gun for that distance, but the same people snivel about my ultra magnums. Some people just like to run their yaps. If I bullet puts a deer right down and passes completely through the animal it 493 yards , its a waste of time to argue that the cartridge didn't perform and at that distance still has the same energy as sticking a 45 ACP with a 230gr bullet against the deers ribs at point blank and pulling the trigger.

This is the Grendel carbine that took the deer, built with a 16" Alexander Arms M4 Carbine barrel.



This is the last Grendel I built, I used a 18" stainless Alexander Arms match barrel. Had it turned down and lightened up, threaded 5/8-24 for a suppressor and shortened to 17". Scary accurate with Factory Hornady 123 A-max match loads.



This is my Grendels best 300 yards groups shot last fall with Hornady match 123gr .

That's a pretty good group hammer. You might be able to tighten it up a bit if you move your scope forward. Remember nose touching the charging handle for best accuracy.

thats pretty sweet big, impressive groups!!!!!! but out of my price range, for the cost of an upper I can buy a whole ar10. Been looking at the 6.8's a little bit, seems like a good round, and building one isnt expensive

[dontgetcrabs]

The Grendel has very little advantage over the 6.8 SPCII out of a 16" barrel. This guy knows the 6.8 very well...  www.ar15performance.com

Hahaha and he's also making a truck load selling them. They were designed entirely for two different purposes. Comparing them is redundant, it's been hashe out. Over and over, the Grendel serves the short, mid and long range soft target applications. While the 6.8 serves the short and a slight step into the mid, then it's all over but the effects of gravity and the laughing from the Grendel section. So is the game of outer ballistics.

Bring your 6.8 title and we will go rounds out to 600 yards for pink slips. The 6.8 SPC was designed for whacking Tango's in caves. It can't hold with a Grendel out to 600 let alone a 1000 yards. Your comparing apples to oranges. I tried the 6.8 SPC and its a dog compared to the Gredel. Wouldn't mind if you took me up on my offer. I could sell that 6.8 to some chump to fund another 24" Grendel upper.

I'd pay to see two guys have a winner take all shoot off.......as long as I'm not one of the shooters. Let us know when and where you guys set this up and we'll all be the judging panel.
