You could always get a Spike's Upper to match your lower. Also, 6061 is inferior to 7075. Primary Arms has a decent price on them. https://www.primaryarms.com/Spike-s-Forged-M4-Upper-Receiver-Assembly-p/sft50m4.htm

Any reason you wanted the Midwest Billet Upper? Why not a forged upper? Would've saved you the trouble of figuring out what to do with the anti-rotation tabs on the rail.

There's a couple up on gunbroker going for $1550. Impact Guns has them in stock for $1599 + free shipping.

The Vltor A5 system should help out some too.

gunbot.net is another site I use.

You could try the Leupold vx-6 1-6 Multigunner scope for around $950. http://swfa.com/Leupold-1-6x24-VX-6-Multigun-Riflescope-P57682.aspx

ALG Defense will be coming out with a 13" Rail. Geissele got a few options at 13" too. More expensive though. What about BCM's new 13" KMR rail? These all come with the barrel nut wrench.

BCM introduced some new lightweight fluted barrels along with their light weight keymod handguards. Their enhanced lightweight barrels are .4 oz lighter than their normal lightweight barrels. The fluted elw barrels are 0.75 oz lighter than the non-fluted elw barrels. Making them over one ounce lighter than the normal lightweight barrels. http://www.bravocompanyusa.com/BCM-14-5-Mid-Length-ELW-KMR13-p/bcm-urg-mid-14elwf-kmr13.htm Just for reference, the KMR is very light. BCM KMR13: 5.5 oz (Rail) + 2.2 oz (Barrel Nut) = 7.7 oz Noveske NSR 13.5": 7.9 oz (Rail) + 3.1 oz (Barrel Nut) = 11.0 oz

What about a KAC URX 3.1? They come in 13.5 in. http://www.knightarmco.com/military/?term=rails-military

Here's a DD V5 LW for a little over your price range, but it comes with an Aimpoint PRO. http://www.gandrtactical.com/cgi-bin/commerce.cgi?preadd=action&key=7109-NS

Colt 6920 for $955, however you'll need to get some compliance work done. Probably cost you another $100 plus the cost of whatever muzzle break you want to throw on there. http://grabagun.com/colt-mfg-co-inc-le6920mpb-car-5-56-16-1-30rd.html?trk_msg=5PFA1B0R42OKV5FRBFBL2KO5D0&trk_contact=C4PS1ITD80JF6JT7BAV74VIV10&utm_source=Listrak&utm_medium=Email&utm_term=http%3a%2f%2fgrabagun.com%2fcolt-mfg-co-inc-le6920mpb-car-5-56-16-1-30rd.html&utm_campaign=GrabAGun.com+10th+Day+of+Christmas+-+Colt+LE6920+Magpul

Here ya go... http://www.wickedlasers.com/arctic

I recently got tinnitus too. It's associated with hearing loss. It all started back in September when I experience dizziness. The doctor's aren't sure, but they think that the auditory nerve became inflammed due to a virus and that caused some nerve damage. The ENT explained the ringing this way... When you have a certain amount of hearing loss, say 25%, then your brain fills in the 25% with the ringing that you hear. He said there really isn't anything that you can do about it. If you want, they can prescribe anti-depressants that will lessen the perceived ringing, but I didn't want to go there. Other than that, he said you should get used to the ringing when your brain becomes accustomed to the lower amount of hearing that you have. Right now, I hear it every waking second, so it's kind of annoying.

Yes, that's the magpul fixed carbine stock. They have for both commercial and milspec carbine buffer tube.

Was there any compliance work done to it? I'd say if that priced included the work, then the price isn't terrible.

You're right, $25 is cheap insurance, and we do spend stupid amounts of money on these things anyways. Maybe it was an out of spec lower? Or worn pin holes?

I've heard mixed review on Bill Springfield. http://www.ar15.com/forums/t_3_4/575594_My_Experience_with_Bill_Springfield_DBA_Triggerwork_net.html http://www.m4carbine.net/showthread.php?t=69659 http://www.hkpro.com/forum/hk-long-gun-talk/188642-bill-springfield-work-any-one-have-problems-too.html You don't need anti-rotation pins if you installed the FCG correctly and there's nothing wrong with the FCG. http://www.ar15.com/forums/t_3_118/486584_KNS_Precision_anti_walk_pins.html Full auto from pins walking? How would that happen? Are you sure you didn't read that pins walk more from full auto firing? Do you have any support for this? Just curious, not being confrontational here.

You could get a Colt for $1099. Grant at G&R has them in stock. And he's a great guy to deal with. http://www.gandrtactical.com/cgi-bin/commerce.cgi?preadd=action&key=6920 However, you'd need to send it somewhere to get some mods done. You'll need to have the bayonet lug removed. Have the stock pinned. And have a muzzle brake pinned and welded. Steve at Adco does good work. http://adcofirearms.com/ Or you could send it to one of the forum sponsors to do the compliance work. I believe Nick from Mastodon Ammo & Camo can help you with that. http://njgunforums.com/forum/index.php/forum/115-mastodon-ammo-camo/

Look at what this guy was doing with a Colt Socom at 1000 yards. http://looserounds.com/2013/08/05/what-will-the-m4-do-at-1000-yards/ Here's something similar on gunbroker. http://www.gunbroker.com/Auction/ViewItem.aspx?Item=366276918

Ah, I see that now. But still.. the rear BUIS being so close to the front is going to make your sight radius tiny. As others have said, maybe you should get a riser for the scope mount... or a different scope mount all together. What mount do you have now?

How come you have a rear buis in front of your scope? And no front buis?

Of all the BCM uppers, why that one? Has a wonky sleeve up front which will serve no purpose for you. Other than making it front heavy. And it won't be removable after you pin and weld a muzzle brake at the end. I'd rather have the BCM over the Stag though. Just not that particular upper. Rainier has a whole bunch of different BCM uppers available. I'd go with a 14.5 lightweight. Pin a BCM Comp Mod 1 on the end, and you're good to go. Not sure if Rainier will cut off that bayo lug, but you could ask. I ordered a DDM4V5 from them a couple years ago. They are good to go.

Good point, I forgot about the bayo lug. I prefer one stop shopping too.

Gotta pin a comp, so that's why I went with 14.5 version. They have the option to pin/weld their Comp on that one.

Something like this would be good. http://www.bravocompanyusa.com/BCM-Standard-14-5-LIGHT-WEIGHT-Upper-Receiver-p/bcm-urg-car-14lw.htm
