Just my .02........
My first AR platform was an M16A2 that I carried as an Infantry Rifleman / Security Forces Marine while in the USMC. I often find myself comparing the quality of civilan AR15's to the quality that I came accustom to on the Colt M16A2.
In my opinion DPMS and Olympic are junk (owned both, and during the numerous Tactical Carbine courses I have attended over the years DPMS, Olympic, Modle 1 Sales, home brews, parts guns, and other tier III manufacturers guns tend to go tits up at a MUCH high rate than quality manufacturers). I have owned several Eagle and Armalite AR's and none of them have impressed me.
For the last decade I have been a Bushmaster type of guy. That being said I currently don't recommend them. Over the last 12 years I have owned 20 to 30 Bushmasters. What I have noticed with Bushmaster is when the demand for their guns are high, their quality really suffers. I really noticed this pre and post Y2K and pre and post Assault Weapons Ban Sunset. In the last 18 months I have purchased 4 Bushmasters. All 4 had to go back to the factory for different quality control / reliability issues. Some of them even had to back to the factory more than once.
I have seen some problems with LMT (uppers not true, etc), not many, but enough for "me" not to purchase from LMT.
Currently I recommend and use Stag Arms (aka CMT), Rock River Arms, and Colt. I would give a definate edge to Stag (CMT) due to the price and features (mil spec buffer tube, covered firing pin on bolt carrier, etc). I recently purchased 2 Stag guns, and the upper to lower fit is superior to any other gun I have on hand (Colt LE6920's, Rock River Arms, Bushmasters, etc)
Here is a post I wrote on another thread on another forum in reference to Stag Arms:
Just my opinion, but during Patrol Rifle classes, SWAT Carbine classes, Carbine classes that I attend, and Tactical Carbine classes that I help instruct, I see more problems with guns that have parts made from several manufacturers.
In a recent carbine class one guy had a complete Olympic lower with a complete Colt lower and another guy that had a complete Bushmaster lower and a complete DPMS upper. Both guys had trouble with their guns. All the factory complete guns were running fine.
Here is a quote from a student who had a gun with a different upper and lower come to a Tactical Carbine class and his gun went tit's up:
"This rifle had previously been part of some sick frankenblaster, and after some bad experiences with it at a Tactical Response Carbine Course, and some sage advise by our own Jeff Carpenter, it has been restored to its core factory components. "See the entire thread here:
getoffthex.com/groupee/forums/a/tpc/f/182106881/m/396100896I just wrote this for a friend who live here in Colorado and had planned on getting a Colt LE6920 once he got back from Iraq:
I've got 3 Colt LE6920's and I paid around $950 each for plus $100 to have Ken Elmore at S.A.W. do his reliablity upgrade on a each gun.
CMT is Contentinal Machine and Tool (not to be confused with LMT Lewis Machine and Tool). CMT and Stag Arms are the SAME COMPANY. CMT / Stag is the sub-contractor who makes Colt's uppers, lowers, etc, and they also make the same parts for Rock River Arms.
I had heard a lot of good things about CMT / Stag and have had the chance to check out quite a few of their guns recently. I am very impressed with the fit, finish, qulaity, and features on the Stag Arms guns.
When comparing my Colt LE6920's to factory Stag Arms M4's here are the only difference I noted:
-Stag has a 1/9" twist barrel, the Colt a 1/7" (but both have the Colt M4 feed ramps). Barrel twist is a non issue as most of us shoot 55 grain to 62 grain ammo 99% of the time.
-The Stag finish was about 1 shade darker, you had to look had at both and be in direct sunlight to tell the difference.
-The Stag has a Colt mil-spec buffer tube, but has 6 positions instead of the 4 on the Colt buffer tube....Because Stag makes Colt's buffer tubes, they are the same spec....Both Vltor and LMT SOPMOD stocks will fit perfectly on the Stag tube.
-The Stag handguard only had 1 heat shiled.
-The Stag has a M16 style bolt carrier that covers the firing pin. The Colt has Colt's nuetered bolt carrier group. I prefer Stag's bolt carrier group.
If you got to
www.stagarms.com they only offer 3 different carbines and 1 20" flat top AR15A3. On Stag's website the guns start off at $900 and go up. NONE of Stag's dealers (that I could find) carry COMPLETE Rifle / Carbines. BUT many of the dealers carry COMPLETE UPPERS and COMPLETE LOWERS (you just have to put the upper on the lower and close the pins).
www.eaglefirearms.net in Brighton, CO. carries the COMPLETE Carbine lower for $215 and the COMPLETE M4 upper (no carry handle) for $429. That is $644 (plus tax, shipping, and transfer fee....still under $700) for a COMPLETE M4 carbine, that is pretty much the same thing as the Colt LE6920. Excluding tax, shipping, transfer fee, you can buy 2 Stag M4's for the price of the average LE6920 (average civilian price on a Colt 6920 is $1250 to $1350).
I just bought 2 complete Stag Carbine's (minus the barrel). I'm putting Rock River Arms mid-length barrels (custom countoured for me by ADCO Firearms) on both guns.
The way I understand it is, CMT has been in buisness as a sub-contractor for well known quality AR15 manufacturers for quite some time (Colt and Rock River Arms). In 2003 CMT came out with a "retail" line of their own and named it "Stag Arms". Don't quote me on this but from what I was told some time ago, it's a father / son team. Dad runs CMT while son runs Stag Arms.
You can NOT beat the quality or the price. A COMPLETE M4 carbine for $644 ...... you can't even build a piece of shit parts gun for that.....It's a NO BRAINER.....there should be NO REASON for me to see another DMPS Upper / Colt lower, or Colt Upper / Olympic Lower, or Model 1 Sales Upper / Bushmaster Lower, or just a parts gun in general at a class ever again!!!
Good luck
