    Oh how wrong you are. With all due respect, this just tells me you don't have a lot of experience with this platform otherwise you would not err so bad in your statement.

    The OP should have the best education to make up his mind and there truth is there is a "WORLD" of difference between DPMS and Colt. Night and day, quality-wise.

    Not to argue with you but the OP should have the truth, not just a well intentioned opinion. With that, I am out.

    ETA: Go to M4carbine.net and check with the industry pro's on their opinions. They will mirror what I am saying.

    No, they are NOT the same round, but they are very close dimensionally and ballistically.

    Without getting into the details, the chambers differ between the two. Suffice to say that if your AR barrel is stamped 5.56, you can use either the 5.56 or the .223 round. The opposite - running 5.56 ammo in .223-chambered guns - is potentially dangerous for a number of reasons.

    IF you get a good deal on a cheaper run rifle, you can do several simple things to increase it's viability for multiple roles.

    1)Get the chamber reamed out to 5.56 specs.
    2) Full auto bolt carrier that is MP tested with the upgraded extractor insert. (LMT is an excellent choice and comes with the insert I believe)

    3) Some people prefer to change the buffer to an H or H2 model. But I believe that is only to increase lag time in the carbine gas systems.

    If you want a good brand out of the box. LMT would be my choice. At least for the upper.

    If you want a nice two stage trigger, I have heard good things about the RRA one. No first hand experiance though since I prefer a standard trigger.

    There is a common misconception that .223 and 5.56 are the same thing. They are not. 5.56 is often loaded to a higher pressure, among other things, which is the most critical issue. There are other dimensional differences pertaining to throat, bullet seat, etc. but what it comes down to in practical terms is that you can shoot .223 in a 5.56 chamber but the reverse is not a good idea. Generally speaking the barrel will be marked with one or the other but unfortunately those markings cannot always be trusted. If you think you may ever shoot 5.56 ammunition it is a good idea to get a 5.56 chamber from a maker that can be trusted.

    Or have it reamed out by a gunsmith. This is increasingly becoming the easier option as more gunsmiths are starting to do the service.

    I've heard good things about Daniel Defense and CMMG. On a slightly lower price point another good brand is Stag Arms.

    Thats funny, since I own or have owned a Colt, a DPMS, a Rock River, Bushmaster and have direct experience with many other AR makes and have shot all these guns extensively and have been using the AR platform for 25+ years thats how I base my statements. How about you. Unless you have extensive experiences with all these makes, and with respect to you, I highly doubt you do, then all you are doing is repeating what you read somewhere or were told by somebody else. You are sounding like a guy who owns a Colt so everybody else rifle if not a Colt or what ever make it is you own is inferior. Thats just not the case. There are many fine makers of AR platform rifles and is not just Colt, Armalite, Daniel Defense, ect. Its like those who say only Glocks or SIGs or HK's are good handguns, they certainly are but many other brands are also and the same holds true for AR's. The vast majority of DPMS, Rock River, Bushmaster and even Olympic owners will tell you they are very happy with their rifles and thats what counts. Who's better or "the best" is open to debate but unless you have long term first hand experience with them all you really don't know do you. Personally, I make up my mind from my own first hand experiences with a firearm, not from things I read or the gun shop commandos tell me which are always slanted one way or another. Make up your own mind, don't let others do it for you!

    As far as this statement you make "ETA: Go to M4carbine.net and check with the industry pro's on their opinions. They will mirror what I am saying".
    Its a perfect example of what I am saying, its you just repeating and "mirroring" others opinions and not making up your own mind from your personal experiences. Most people here are looking for and want to know opinions from forum members very own experiences with a specific gun not just people repeating rehashed verbage from some other site. Anyone can do that. If you want to believe DPMS, Bushmaster, Rock River, CMMG, Stag and other some AR makers are "hobby rifles" as you say, since you don't own one or have experience with them....OK thats your opinion and I respect it and we get it now but with a big grain of salt.

    And lastly the quality of Colt products in general not just AR's has been going down hill for many years which is sad to see.

    I have a Colt and have had both Bushmaster and RRA and all of them have functioned 100% and still do.

    Well since I'm always one to go against the grain, I got myself an Olympic Arms K3B in late Dec. @ a gunshow Private sale for $650.

    It was made in '05, still under warrenty (life time). Replaced the gas rings, and have put 1260 rounds throught (both NATO spec and .223) it and LOVE IT!! Single stage trigger, nice and crispy. Pretty darn accurate if I must say.

    To me, it's been reliable and smooth. I only use Cproducts mags with it, they fit great and fall out on their own when released. I've done some custom work to it and trust it to go bang when I squeeze that trigger.

    Picked up two of the 36 peice sets from Cheaper Than Dirt that replace springs and other parts that tend to wear out. Couldn't be happier.

    I've got a nice LWRC rifle and it runs like a top. Haven't had a single issue with it in the year+ I've owned it. They're pricey, but the proof is in the pudding.

    Even if I went with another brand (not that I would) I'm a piston AR guy forever now. I'm even on the prowl for a piston AR-10 now...

    They run cleaner and cooler without the gases venting directly into the chamber. Many of the first gen piston driven mod/upgrades were not well designed and prone to failure for a number of reasons. Today I would trust any of the major quality manufactures piston driven AR's or upgrade kits.
    I have Bushmaster and it has proven to be a good solid reliable accurate shooter. After reading the reports from the sand box and the thread Gunzilla The Worlds Best Gun Cleaner I only clean and lub mine with Gunzilla. I may opt for Bushmaster's piston driven upgrade as it was designed for this gun.

    Currently I have been researching the POF (Patriot Ordnance Factory) USA P308 MRR From everything I can find so far this is THE AR to have. A piston driven, 308 made to run dry as in unlubricated apparently because all the internal parts are Robar NP3 coated, electroless nickel or hard chromed to be self lubricating. All reports to date claim this is a rock solid indestructible tac driver. Time will tell and I do have some time as it is more than double what I paid for my Bushy. Still if it holds up to its reviews it will be worth every cent IMO.

    That's an awfully expensive suggestion for something lube will handle nicely. "Cleaner" is also relative; check up around the gas block and you'll find where all of those dreadful gases are going. As has been said by folks who know a lot more about these rifles than me, adding the piston just changes one set of problems for another. Not an especially strong argument for at a $500-$900 upcharge over a quality AR-15.

    The NP3 isn't exactly exclusive to that POF rifle, nor is the idea of using low-friction coatings to minimize the need for lubrication. FailZero's EXO coating is a pretty proven technology (good write-up here). Ionbond and Melonite are even better, and if you feel like overkill can be combined. Heck, Ionbond BCGs are even available from Bravo Co. Send an upper receiver and BCG to someone who can do one or both of those processes and I'm not seeing what edge that POF rifle has. Just sayin'.

    I have used a DPMS since Bill Clinton's first term as President. I had one very minor problem with it, which the factory offered to fix and pay for shipping (I fixed it myself). It has only ever had one fail to feed, and that was after it was filthy from feeding it cheap ammo (don't do either of those). I don't know if it is still the case, but the 3-gun competitors used to swear by the DPMS guns.

    I also recently built an AR from a complete Stag carbine upper (LH) and an Anvil Arms lower. Seems to work so far.

    Those are my personal experiences. As far as all that other stuff goes, some of it is OK (MPI), some is worthless (shot peening a bolt to relieve stresses from manufacturing involves taking ball bearings and shooting them at the bolt, used to prevent stress corrosion cracking) and some are of dubious value (mil spec steel in the barrels are the minimum the government will accept, not the best steel for barrels).

    Worthless ??? We used shot peening at Boeing to strengthen some parts installed on the aircraft we worked on. I would hardly call the process worthless.
