If it's just the upper that is giving fits, get one direct from DPMS, it's cheaper and free shipping even if you need to pay tax: http://www.dpmsinc.com/308-Upper-Receiver_p_2180.html http://www.dpmsinc.com/308-A3-Receiver-Stripped_p_257.html

Yep, had some ooooooold milsurp 7.62x51 that I couldn't get to reliably fire. Hiperfire 24 fixed that problem in no time flat. Additionally, no issues with fire/safe on my DPMS lower.

It does. It comes with a proprietary steel nut that just covers the threads(no timing of the nut needed for the gas tube). Lots of negative reviews on it from Midways site mainly due to it clamping on instead of threading. I won't say it's rock solid but after tightening it I feel it's solid enough to not move under normal conditions(I haven't encountered a 12+" rail that doesn't move if force is applied). It fit like a glove with the DPMS specific lower and as you can see is same height(can't say I wasn't a little worried). Considering going with a Mission First Tactical carbine stock. Have it on my AR15 and love it. However it's low on my list. For me the weight closer to the body doesn't matter as much as the weight further out. Waiting on TacCom to release their UL recoil system for the .308. Again, I run it on my AR15 and it works great. Much nicer to spend $25 on an upgrade than a few hundred. Of course bigger benefits would be realized by doing both. The comp does wonders on a .223 platform, I'm hoping it will make the .308 stay as flat. If it does I'm willing to pay the few oz for the performance. Though I do not envy anyone standing next to me. That effer is going to be loud. Exactly. This is another place that I don't mind a few oz's as not only do I get the longer sight radius, but also can hold my hand out further. Thanks all for the welcomes. Now I'm off to say how awesome my F class skilz are and you you are all idiots for choosing anything less than a 32" barrel. :))

Thought I would add some data. Relatively new to the LR-308 platform. I got a 3rd hand custom DPMS with a SASS barrel and CF forearm that shoots old mil surp ammo way better than anything should, but that SOB is heavy with no provision for a front sight that's needed for 3-gun Heavy Metal(or He Man) division. Here's what I used for my build. Didn't come in quite a svelte as the previous one mentioned: Part Weight(oz) Description Upper 14.2 DPMS .308 A3 Receiver (Stripped), Part Number 308-FTT-EA BCG 17.55 APF Armory Bolt Carrier LR-308 Nickel Boron, APF Armory Bolt Assembly LR-308 Nickel Boron - comp kit 0.8 DPMS - 308AR BOLT COMPLETION PACK(Firing Pin, Cam pin, Retaining Pin) CH 1.3 Bravo Company / Vltor 7.62mm 308 Mod 4 Charging Handle Barrel 38.3 Rainier Arms Match™ .308 Barrel - 16 (ODS); Stainless Steel Match Grade Blank Gas Block 1.55 Low Profile Adjustable Gas Block Set Screw Mount .750 Mil-Spec 556 nitrided Gas Tube 0.7 Spikes Tactical - Melonite-Coated Gas Tube, Mid-Length Handguard 13.7 Samson Evolution Series Customizable Free Float Handguard DPMS LR-308 with Low Profile Upper Receiver Aluminum Black Sight - F 1.3 SAMSON MANUFACTURING CORP - AR-15/M16 FIXED FRONT SIGHT Sight - R 1.55 SAMSON MANUFACTURING CORP - AR-15/M16 FIXED REAR SIGHT Comp 3.85 Fortis Compensator RED™ 308 w/ crush washer Even though this adds up to 94.8 oz, the completed build comes up as a weighted 95.1(5.9 lbs) - so obviously some rounding errors. That's a little over 2 lbs lighter than the 18" bull barreled SASS scoped upper. With the lower I'm at 8.7 lbs. Looks like I can trim a little weight if I go from my full A2 stock to a collapsible - which I may do. No comments about how the comp is installed upside down. I realized it just as I was tightening it down and then broke my fixture as I was attempting to take it back off.
