Anyone know any good ar-15 for under $750 or so? I need it for south Texas hog hunting and the hogs are out of control.

Answer to your question

Remember you can always build it instead of buying complete.

The only warning I give to those trying to build instead of buy, especially if cost is a big driver, is to consider all the tool costs too. Every person has different tools at their disposal, be it your own or stuff u can borrow. On one end of u have a wide set of punches, wrenches, clamps and access to borrowed ar specific tools then it's literally cost of materials only.

The other piece of that, as mentioned in the other thread, is that Frankenrifles usually bring much less versus factory guns should you need to sell it.

Mines made by battle rifle company they are based about ten minutes from me in clear lake I've put a couple thousand rounds through it and never had a single failure I would definitely buy from them again

my suggestion for a new AR guy is to get a rifle and then modify as you see fit once using the gun a couple times. I bought a relatively cheap gun in a Smith and Wesson M&P15 optics ready, and since then, I have dropped a new trigger (highly recommend the gissele SSA-E) and changed out the hand rail to free float the barrel (which required me to change out the gas block too), and then changed out the grip and stock.

I had a very useable gun until I acquired all the pieces and tools and then went about fixing it up in one day. Was a very fun day for me filled with lots of youtube videos and some trial and error, but in the end, my rifle works great and the mods made a noticeable difference to performance and comfort.

But then you should also consider the cost of buying a factory rifle and then changing out parts to upgrade it to what you want. If you are buying a rifle, swapping the trigger, front rail, gas block, grip, and stock, then what parts did you pay for in the beginning? You paid $750 for a lower, LPK without the trigger, upper, barrel, BCG, tube, buffer, and spring. And what are you doing with those parts you pulled off? Sell them? They aren't worth much if you can actually find a buyer so they go into storage or into the trash. For the price of those tossed parts, you probably could have bought the tools needed.

For the first AR, buying a factory rifle might be a good idea so you figure out what you really want on the rifle and then upgrade. But if it's going to turn into several rifles, then building might be the way to go.

Is there also a difference between the 223 and the 556 national?

It's a pressure issue, guns with .223 are rated to shoot only .223 rounds which have less pressure than the military 5.56 round. A 5.56 stamped gun will shoot both. Very slight differences in both and some people say that guns rated for each should only shoot each and not interchange due to throat issues and bullet seat depth and stuff like that, but most people say that's a moot point. Best thing to do if you want an AR is get one rated for 5.56, then you don't need to worry about it.

So getting a 556 you can still shoot that round and a .223 right. Kinda like a .357 mag with .38 special rounds

you are correct

You can also get a 223 Wylde which will shoot .223 and 5.56.

What is also the best twist rate for an Ar

What grain bullet do you want to shoot?

Either 65 or 80 grain which has a better punch to it?

I bought this one last year on sale for $499 w/ free shipping. I already had a rear stock to replace the one that came with it, and just put in a new trigger. It's been an excellent rifle so far.

For heavy bullets, you want a high twist rate like a 1:7. The down side of the high twist is that you can not shoot the light weight bullets. You will find a lot more factory hunting ammo in the 62 or 65 grain than the 80 grain.

1/8 is the most versatile. If you aren't going to shoot heavier than 70gr than you should be fine with 1/9. If you shoot heavy all the time then the 1/7 might be your best choice. Some of it will also depend on the gun/barrel, there are plenty of guys shooting 1/7 that get good accuracy with 55gr bullets.

My AR is 1/8, .223 Wylde.

I get god accuracy with 55gr bullets, never tried anything less and never will. My barrel is 1/7 because I mainly shoot 65-72 grain bullets.

1:7 here that hits 8-10" steel from 200 yds with steel "junk" 55gr ammo and open sights.

I'd have trouble saying you can't shoot 55gr with 1:7.

What is the most universal twist the 1:9
