Re: Help on AR's
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Jr_V</div><div class="ubbcode-body">Build or piece an upper and lower together. Colts are nice if you need a name, but there are tons of other options out there too. Besides a HB what barrel length you looking for? There are some nice varmint uppers that you should be able to get your hands on pretty easily. </div></div>
Kind of what you said, only buy a Colt if you need the name, are looking at resale value, or come a cross a really good deal. Unless you find a Colt CR6724, this would be an easy no brainer one stop shop for you.
Otherwise build from scratch and mix & match. Prices have gone up on everything but you can still put your self together a very good shooter from parts. Stripped uppers, parts kits, BCG's, barrels, free-float hand guard options, the sky's the limit. First figure out how much you want and can spend, then set a budget. Trust me. $4200 later and I am about done with my SR15.
If you're not comfy with assembling an upper buy one from Larue, Noveske, MSTN, ADCO, White Oak, Compass Lake or any reputable builder and pin it to your lower receiver. If you buy a DPMS upper remember chamber dims. They might say they are 5.56 but they are really .223. This is another consideration building an upper. 5.56 or .223 and that debate can go on for ever. Do some research and you'll come to your own conclusion.
Shop around and lowers can still be found at a reasonable price. Check out LRB as I think they still have some of the best prices for an excellent lower (they have stripped uppers too). They can be bought stripped or fully assembled (but with standard parts not NM) I have one with a Colt 20" HBAR A2 upper pinned to it and love it.
Then figure what trigger you want. Single stage, double stage, kit, or drop in. There are some good write-ups on triggers over at m4carbine.net and ar15.com
But in the end your money is mostly going to be spent on the upper, hands down. Then just like any other rifle build buy some nice glass to mount on it. Building an AR to shoot sub-moa is the easy part, the rest is up to you.
This is all just my .02¢ as there are a zillion answers and opinions on building precision AR's. Good luck buddy.
