Barrel obstruction, out of spec barrel, out of spec bolt, incorrect headspacing, firing pin stuck out that contacts primer before action locks closed, nose of double feeding round contacts primer of chambered round, overheated barrel or chamber loses tensile strength, out of spec or improperly installed muzzle device, and a muzzle device obstruction, and that's just off the top of my head.

Do you know anything about the system at all?

I believe the point you were trying to make is that most Colt issues are not caused by manufacturing defects, and I believe that is a very valid point. Most firearms issues are the result of operator error/training issues. Most issues with simple mechanical consumer goods are operator error/training issues. Heck, the same is likely true of even complicated electronic consumer goods that were imported from Asia.

Maybe you should also try reading comprehension.

I said in spec..


And many of the things you reference don't cause a kaboom, as in catostrophic failure , a simple bore obstruction, not colt specific.

The point I made was that colts don't just blown up as the poster I referenced stated, because they are colts..



Never saw a double feed round or firing pin ignition out of battery do more than blow the magazine out the bottom or partially out, not a full grenade of the upper receiver..as in blow up..

Yes I know the system and have been a colt trained armorer for 15 years, and responsible for about 200 agency rifles including about 25 full autos from various manufacturers, I am not an expert, but I am qualified.

One thing I don't do is suffer fools .

I agree, when I first saw his post I thought "Wow, does he not know who he just accused of not knowing the AR platform?"

Once this "test" was declared to be repeatable and scientific I knew no good could come from it.

You wrote inquiring about how a Colt could kaboom with an in spec round. You failed to specify an in spec Colt, genius. I addressed the question you actually asked, not the question that you wanted to ask or would have liked to have asked.

My goodness, your ability to capitalize and use punctuation rivals your word skills. How can you write like you do and blame other people's reading comprehension skills when they do not always grasp what you meant to communicate?

Are you referring to the Colt vs. Sport test, the Matthew Courtney vs Mayhem Like Me disagreement, or the fnfalman vs. bmoore spat?

I agreed with Mayhem. I guess he missed it, too.

Round counts on each rifle are now between 400 and 500 rounds, with no malfunctions observed with either rifle. The bulk of ammo fired through each rifle to date has been from the same Wolf case as the Wolf used in the accuracy tests with the balance of the ammo being the other ammunition documented in the ammo tests. Any existing throat erosion is, at this point, to little to be accurately measured with our W.H. Merchant gauge. Chambers, BCGs, and actions have been completely cleaned, and barrels have had a bore snake with 2 inches dampened with Hoppes #9 pulled through them, followed by a dry boresnake 10 minutes later. Inspections during the cleaning process revealed nothing of note other than polishing of some parts. Would anyone like any particular measurements or observations made at this time?

Great test, thanks. Any plans to spend a Saturday and run 1K of Wolf per gun and see what happens?

POI for one of our courses involves 1200 rounds fired over a three day week-end, but most of the guys taking that course bring a rifle instead of renting one. When a students rifle takes a dump early on day one, we would see a high round cound week-end, so it will happen eventually.

Matthew Courtney, I would like to suggest that you take all of the information you have provided in this thread and start another one. Take all of the information, organize it, and put in it the OP, and edit the OP as new information and tests become available. I think it's hurting your thread with all of the pointless pissing contests, and random conversations about things other than your OP. I'm sure a lot of people would rather see all of your painstakingly gathered information in a clear, easy to read format, as opposed to searching through 11 pages of random information in hopes they find actual test results. Just a thought...

I agree completely. I have been subscribed to this thread and have read every post. I haven't posted as I have nothing to offer. Lots of trolling, baiting, ad hominems, "fanboy" attacks for no reason...the actual data, experience, results...they are getting lost.

I know there hasn't been a whole lot yet since the round counts are still pretty low, but what is there is good and ought to make great groundwork for what lies ahead.

Can you edit into this OP?

I'd mostly just like to see the data all in one location/post/consecutive series of posts
