    Thinking of getting a .308 upper for my AR.
    I won't to be able to go from 5.56 to a highly accurate .308 capable of making shots at around 600 yards. Just wondering if anyone has recommendation on what upper, barrel, BCG , and trigger combination I should use as long as its a reasonable price.

    I dont believe the 308 upper will fit the AR15 lower. They are usually on an AR10.

    JTJ is correct. You need either a .30 wildcat for the AR-15 or you need an AR-10 for .308

    600 yards is about the end of business with a .308 anyways, and that is a moon shot. You would need to add a 20 MOA rail to you upper to be able to crank you scope's elevation enough to get there.

    Do you want stopping power, or range? I can get you one, or the other in an AR-15, but both is going to be a bit of a stretch (pun intended)

    6.5 Grendel would probably meet most of your needs, but you will have to reload to make it cost effective.

    I thank I'm just going to have to get another gun. I won't range and power plus readily available ammo. I know its a lot to ask for. I have a Winchester 70 in 30-06 but I don't fell like it is enuf.

    Define stopping power.

    The Grendel will throw a 130gr bullet at about 2750fps and is supersonic out to 1200 yards.

    That would def work. But the problem is its not easy to come by with out reloading. Which may not be an option.

    15,

    Dillinger is correct. They do have a 300 Blackout upper but not good for long distance. However as JD advised the 6.5 Grendel is one fine round and has a lot of range capabilities. It will turn a prairie dog inside out at 400 yards. And some have been shooting it at 1000. Hornady is also now making brass for it and I would assume ammunition is not far behind if the demand continues. I did use Lapua brass but you sure do not want to lose any of them when shooting. Some say the casings can be reloaded about 4-5 times. I will tell you they are very easy to load also and have a good range of bullets for them. There are a few on the Internet that offer 6.5 Grendel ammunition. But as stated the 308 upper will not fit on your AR-15 Receiver. Good Luck with your choice.
    This is a Sabre Defence 18" 6.5 Grendel.

    I am trying to start reloading so I might give in to the 6.5. Just a few more questions. At what rai he will it still be affective on deer. What would be the best upper to go with at a reasonable price. And I'm sure I will have to by new mags.

    If you go with the Grendel, you have some options.

    First off, you don't need to buy a new gun, just an upper. Two pins and you are in business with a brand new round, greater range and more firepower.

    Here are some links to look at if you are entertaining a Grendel:

    http://www.prexis.com/Merchant2/mer...Code=P&Product_Code=AR65&Category_Code=AR15UP

    And there are more out there if you want to pursue this line. I ALMOST built one of these myself before the last election.

    600 yds is in the effective range of a .308 or your .30-06. 1000 yards would be closer to the "moon shot" range for those rounds.

    6.5 Grendel is a promising round. I'd like to see it get more traction as a common round with more manufacturers making ammo for it.

    $2129 just for the lower????!!!!!!!! They can keep it. It's hard to believe all the uppers that will go with my M&P lower. Everything from .22lr to .50 Beowulf even .458. I can't use the 2nd most common AR type upper. Well I thought about it and I decided to get the 6.5 upper and a AR10. The whole point of me getting the new upper was to have a more accurate and harder hitting round at longer distance without having to carry an extra gun. But hey it's not all about getting ready for the next D-day. I am using it as an excuse to add to my collection. Also if shtf that would be another person I could arm.

    No, the colt is a complete rifle. 308 upper AND lower

    It can be converted to accept a standard 5.56 upper by changing the upper and adding a magazine well adapter.

    In essence, you get a lower reciever that can shoot everything an ar10 and ar15 can.

    The only thing i'm unsure of is if your want a large caliber converision, I think you need a special colt only upper reciever. Not sure tho. So if you want a caliber like a large caliber 6.5 creedmor you MAY have to source a proprietary colt upper to build.

    for the price tho, you can get a complete ar10 and a ar15 and instead of one lower and two uppers. BUT if you want just one lower, and like 3+ uppers then you start saving money.

    Personally, I think its best to have 2 or 3 lowers, like a ar15 standard, ar15 precision (rifle extension, precision trigger) and then a big boy ar10 lower, then have as many uppers in calibers you want. To each his own tho.

    30-06 will reach out a bit further than 308, it can use heavier bullets in 180-220 grain much more effectively than 308. carlos hathcock used a winchester model 70 in 30-06 for most of his sniping in vietnam. if you dont know who that is read his biography very interesting individual.
