What is the purpose of this upper? Is this your first AR? I understand you want to learn, but you might be better served by buying an upper first and then trying for a build on your second go around. What do you think you will learn by the experience? And I'd skip most of that stuff on your list if you're looking for a quality build. Outside of the WMD BCG (which really isn't necessary), the BCM charging handle, and the Colt barrel nut, the rest of it is not that good.

Here's the method I've used before. http://njgunforums.com/forum/index.php/topic/30623-how-to-pin-magpul-ctr-stock-without-drilling/

Why does he need a card to take them to the range?

Check out the bad-ass thread on m4c Their rep (Duffy) said it. http://m4carbine.net/showthread.php?t=54648

If needed, I'll apply too.

Geissele is coming out with a gas block with a pre drilled hole for a pin. Here's a good description at primary arms. Geissele's website doesn't have a description yet. https://www.primaryarms.com/Geissele_Super_Gas_Block_SGB_p/ga-sgb.htm

I would be more concerned with bolt breakage. You can't see material defects.

I'd just check over at m4c on their "The Official Where Can I Get It Thread" It's stickied at the top of the AR General Discussion forum. Sign up and subscribe to the thread to get notifications. http://m4carbine.net/showthread.php?p=1500749&posted=1#post1500749

I believe the STR shares the same locking mechinism as the CTR so you should be able to.

You could give www.sightsandtrigger.com a try. They don't have a 2013 schedule up yet. Safe queen? Colt? Really? A wise man once said, "Colt builds War Horses, not show ponies."

That's what you get when you have an extremely rare lower. The lowers themselves go for more than $2k and this was before all this craziness.

Or you could just give your upper to some to hold for you while you do the pinning.

I've heard that if it's on specialized's website, it's in stock. Hope its true.

Another recommendation for G&R here. Have them send you the lower without the stock. gandrtactical.com You can email them and have them put you on their waiting list. They will be receiving some Jack carbines too if that's what you want.

Nope, nothing I would change there. Everything is gtg.

They are holders of the TDP and whatever they make, you can bet it's to the correct spec. But it's not twice as good as the DD.

A5 kit is top notch. Since you're getting all top notch stuff for your lower build, might as well go for it. I have one. And I'm order another for a second build. It's only slightly longer than the regular carbine receiver extension. So, you're not really sacrificing much in length to get more recoil reduction.

I have this one. It's built like a tank. http://www.hammerheadrifletool.com/HammerHead_Rifle_Tool/HammerHead_Rifle_Tool_Home.html But it doesn't work with some receiver plates. Like the Magpul ASAP.

Best would probably be Colt, but they are REALLY pricey. http://www.specializ...5-1161-279.html Daniel Defense makes an excellent LPK as well. Midway has them on back order. They say they will be back in stock on 12/31. It has a grip and trigger included though, but it's always nice to have spare parts. http://www.midwayusa.com/product/126821?cm_vc=S014 Palmetto State Armory has their LPK w/o trigger group in stock right now. They aren't bad from what I hear. http://palmettostate...group-2842.html If you really want to piece it together, you can always go here. http://www.operationparts.com/category_s/50.htm Top half of the list is DD parts.

No problem. Figured it was an oops. That's why I asked. I hate posting from my phone too.

Daniel Defense? Where'd you get that information? Are you responding to the question of which receiver that is? If you are, then you are incorrect. This is a Zombie Defense lower. http://www.zombie-defense.com/lowers.html Pretty sure Daniel Defense wouldn't associate themselves with the zombie craze going on.

That is most definitely a flash hider, not a compensator. AAC has muzzle brakes. They can be found here. http://www.advanced-armament.com/Muzzle-Brakes_c_32.html

Sounds like you want a Colt 6920. You'd need to get it modified to be NJ legal though. Remove the bayonet lug, pin a muzzle brake/compesator, and pin the collapsible stock. BCMs are good too. If you went that route, you could get the upper and lower separately and do the work yourself. Kinda hard to get a Colt at the moment. http://dsgarms.com/P...nfo/CO6920.aspx Out of stock, but they have a good price. Mods will probably cost you about $100, not including whatever muzzle device you want to pin on the end. BCM lower with A2 stock. Wouldn't have to pin this one. http://www.gandrtact...tion&key=LWR-A2 Could get any of these uppers. http://www.bravocomp...-Group-s/27.htm http://www.bravocomp...-Group-s/28.htm http://www.bravocomp...Group-s/135.htm http://www.bravocomp...-Group-s/29.htm If its out of stock, sign up to be notified. They go outta stock quick, so you'll have to be fast when you get the email. You'll also need a BCG, since those uppers don't come with one. http://www.bravocomp...20auto%20mp.htm A charging handle. This is a great upgrade no matter what AR you decide on. http://www.bravocomp...d%204%20556.htm Back up iron sites. Some say you should learn this first before optics. A good white light if you're planning on using for home defense. Sling would be a good idea too. But definately lots of mags and ammo so you can train/practice. If you want to spend a little more and get an AR with a great rail system, you could get a Daniel Defense. They're in the $1500 range. I think PK90 (forum member/dealer) has some in stock and NJ modded. http://www.colddeadhands.com/

No wait on the DD. http://www.rainierarms.com/?page=shop/browse&category=ar15rifles_danieldefense Rainier Arms also does price matching for any in stock DD rifle at a competitors site. They'll do the gunsmithing for you too.

You'd be surprised that the MOE handguard isn't the lightest thing out there. There are some rails that are actually lighter. Check out this chart. https://spreadsheets.google.com/pub?key=pwswheghNQsFnUZMkZNF2DQ&output=html
