    Don't get me wrong I'm not an expert like Coach W, trophy 8 or any of those other guys but from what I've seen its cheaper to build something in the AR15 platform than it is the AR10....

      I did a dpms lower build for my first built. Very easy. Get the trigger and stock you want then bought a complete upper. The uppers on ar-10 platform can be a little trickey do to no standard spec, such as gas port size. But if you buy a complete upper with bolt carrier group and build your lower you will be good to go.

      Spend your money on the Good barrel and trigger, bolt carrier next.

        trigger and barrel is were I would spend the money. I am currently looking to build a 6.8. and in the same boat. not trying to bust the bank.

          Always wanted a 6.5 Grendel to try out. No experience with it though. Just partial to the 6.5 ballistics coefficient and think it would be cool to have an AR in one. Good luck and God bless.

            Haha. Now I have been looking and want one too.
            Here is something interesting in your price range. No personal experience with them but someone on the green screen was talking about radical firearms the other day and they didn't have any issues on 2 builds. They are located in stafford tx and say they have a lifetime warranty.


            Here is their Facebook page. If you scroll down, have a special on a 6.5 grendel with 16 inch barrel for $699. That leaves room to upgrade a little if you don't like the stock or trigger.

              If your son is in sniper school now, you will not be able to compete with Uncle Sam and impress him with anything long range or 308. That would be like giving an apprentice plumber a 14 inch pipe wrench when he works with 36's on the company truck every day.

              Go the opposite direction, CQB entry short to mid-range, big boom, big fun gun that can still reach out to 350 yards, .50 Beowulf for close to $1000. Buy the upper from Alexander Arms and put it on a cheap PSA AR lower with a very good trigger and he will be happy. All his friends will want to shoot it at the lease while having some beers and he can slam anything that walks in North America.

                I second the grendel. In your price range you're looking for a button-rifled barrel, so I'd say...blackhole weaponry.

                  Before I offer a suggestion I need to know range and usage?

                  At a price point of 900 max you're stuck in the AR-15 platform.

                  But there's alot to choose from in the AR-15 so you're in luck. BTW I'm no expert. I've built a few and been around em all my life. Anybody can put an AR together. It's like lego's for adults. If you're looking to save money do it on anything but the trigger, bolt, and barrel.

                  If you're looking to have an optics ready package for 900.. i think you're out of luck. But if you want a nice bare rifle for 900 we can definitely help you there. Just need to know some more particulars first.

                      Having a Grendel built myself, was actually lookin at doin a Creedmoor till I looked at the Grendel and bieng able to stay with a small rifle platform was the deal maker for me.

                        I think I have a LOT of research to do!

                          I would agree. Start by heading down to your local academy, walmart , Gander etc.. see what ammo is on the shelf. Stick to one of those calibers. At our local stores you can pick up 300 blk, 5.56, and 6.8. Decide what you or he can afford to feed it.

                          Then think proprietary stuff.. 5.56 and 300 blk have readily available parts. TONS of them. . Others not so much.

                          5.56 is the cheapest AR you can get in. Just keep in mind all your options. Don't focus on one ballistics chart. Owning a firearm is more than liking a balistics table. Especially one that eats like an AR does. Maybe the only up side of the AR10 in 308.. 308 is maybe the cheapest 30 cal ammo available. But 5.56 is way cheaper if you think in terms of the ammo bill later.

                          Pick a caliber. That will pick your platform.. then we can help you find deals.. at this point the market is flooded. You might step into a used deal for decent.

                            I just though he would want a different caliber than the 5.56. Remember some of his comments about the round during his first tour in the Land of Sand. Any additional comments about the 300 blk? Pro's/Con's? I have NO experience with the 300, Grendel or Creedmoor either.

                            Obviously besides the build, ammunition availability is of big concern as stated. As W stated, I have made a habit of visiting different stores and on line for ammo per price and availability for several years now.

                            Thanks all and keep 'em coming..."Old dog is learning new tricks."

                              The 6.5 grendel is an ar-15 pattern round that requires different mags and a different bolt face than a 5.56. It's an excellent round for short/long range and is suitable for hunting. Many consider the optimal barrel length to be 20", but even 16" works pretty well.

                              The 300 BLK is also an ar-15 pattern round that uses all the same stuff as 5.56 (mags, bolt, and cut/resized brass). It isn't too fast, but it'll put down game like deer and hogs just fine (as long as you're supersonic, results vary greatly with subsonic). The 300 BLK real seller is that is shines in short barrels, as it is a pretty efficient round and doesn't lose much velocity between 9 and 16 inches.

                              The creedmoor is an-ar10 pattern cartridge, that and the 260 are the best round for that platform. Basically it's a 6.5 grendel that's heavier and hauls significantly faster.

                                If you want something with good long range ballistics in a standard AR-15 platform I would look at the 6.5 grendel or even the 6x45 or 6.5x45mm round. 300 BO is a short range pig hammer, not good for much at any longer range. I have a 300 BO and I love it but it's a pretty limited round.
