A guy I work with bought one a couple of weeks ago almost new, with about 50 rounds through it. His extractor has been ripping up cases left and right. He was going out this weekend to try it out again after stripping it down doing some work to it.
I don't know if this is common with a new one or not, just a word of caution.

I am admittedly NOT an expert where AR15's are concerned, but I am a fairly prudent buyer.
I purchased my DPMS 20" about one year ago and have probably put about 500 rounds through it - PMC brown box and Israeli stuff - certainly not enough to legitimately warrant a long-term reliability report. But, I have yet to have a single malfunction of any kind. The only real complaints I ever hear about DPMS is the fact that their barrels are not chrome-lined.
So far as I'm concerned, BIG DEAL! I've got a news flash for all of those who claim that a chrome-lined barrel is essential; There are about a zillion non-chrome-lined rifles in this world, some more than a century old that saw the ravages of a couple of world wars and still shoot great. If your using non-corrosive ammo, and do a moderately good job of keeping your weapon clean, you'll have no problems and that rifle will shoot fine for a lifetime. And many pundents claim that a non-chromed barrel may in fact be a bit more accurate.
In my opinion DPMS gives you a pretty good bang for your buck.

" His extractor has been ripping up cases left and right..."
He wouldn't happen to be shooting Wolf ammo, would he??
January 26, 2003, 08:55 PM
No, it wasn't Wolf, I know that for sure.
They were his reloads and other manufactured cartridges.
I don't know exactly what/where the problem was. He told me that he thinks he may have found the solution and was going to shoot it this weekend.

I bought a DPMS National Match rifle 2 years ago and have not had a single malfunction with over 1,000 rounds. I highly recomend DPMS, they have great customer service. It is every bit as acurate reliable as my Armalite NM.

Have two. Both slickside alu uppers. Only problem I've had is once or twice (long ago) the round would not fully seat/bolt not fully forward. ejected offending round(s) and continued on. These were encountered with the Lo-Pro Classic, under 200 rounds fired at the time. No other problems at about 900 round in the Classic. No problems with the Extreme, about 200 rounds fired through that.
IMO, if you clean your rifle barrel thoroughly and keep it in a well controlled (temperature/humidity) area or coat the unlined bore with a light coat of potectant when putting it in long storage, not much need for chrome.

the overly exuberant extractor could be over function due to an oversized gas port
or a sticky chamber

Excellent quality. I also own a post ban 16" carbine. Not having a chrome lined bore doesn't bother me. As was said it uses Mil_spec or better. On some parts where palstic is acceptable, DPMS uses metal. In addition to the the receivers being anodized they receive baked on teflon. Over on another board believe it was pistolsmith, Ted Yost rates the quality as being equal to Colt's good days. Overall I am extremely impressed with this rifle.

Between my son and I, we have 3 DPMS's and they all are really good shooters......you just have to watch what kind of cheap ammo you buy.........one of ours wouldn't shoot Wolf ammo, but, the other 2 would.........I bought some S&B and American Eagle, and no problem so far........Black hills always shoots great....

I've got one in A2 configuration. Couldn't ask for a nicer gun. Tack driving accurate, too.

Just to update my story:
I talked to my friend at work today. Apparently whatever he did to the rifle did the trick. No problems whatsoever this weekend.
January 27, 2003, 10:39 PM
I have two and thay both have functioned flawlessly. Probalby 2000 rounds throught them both, handloads and BlackHills.
Earlier posts are correct about the chrome lining of the barrels. In combat, no doubt, on the range, not necessary and a slight detriment to accuracy as stated earlier.
The ABCD's of AR-15s, Armalite, Bushy, Colt, DPMS...
