Lots of traditionally rifled barrels like the Colt's shoot better after they have been broken in. We shot 30 rounds of q3131 function checking the gun and sighting it in before starting the test. Plus, there is quite a bit of data out there regarding the suitability of 1/7 barrels for varmint weights. My sample of handy ammo might have been biased against 1/7 barrels because I didn't previously own any. Perhaps we should get some 75 and 77 grain loads to balance out the ammo spectrum.

I'm not surprised that the Sport groups tighter than the Colt. After all it isn't "milspec" and probably built to better dimensional differences and materials. Hehe.

Let's face it. Colt owners (myself included) own the guns because of the Prancing Pony. Smith&Wesson wheelguns and pistols have always been superior and I'm not surprised that their version of the Mattel Toy is also superior to Colt.

I am still surprised by the result of the Black Hills ammo. Expected more from those.

The 1:7 barrel should favor heavier loads. The light varmint loads should shoot like crap out of both, in theory. Maybe stick with the 55 gr and heavier?

How many 5 round groups are you shooting with each ammo type, one per gun?

I know you are just trying to push some folks buttons, but I don't think we can come to that conclusion based on the data. Let's see what happens 5000 rounds from here. Remember, this is a marathon, not a 50 yard dash!

Yep, it remains to be seen, but my money is still on Smith&Wesson. The company is well known for making better products than Colt, like it or not.

My money's on Colt. The military's money is too, and not because Colt is the lowest bidder. I feel very comfortable with my M4 and RDS when I step out the door to go on a combat mission.

Matthew I am one of the people who frequent the M&P15 Forum over at S&W. I think you would be right to change your test ammo away from the lighter weight stuff. Make 50 your lowest, I was totally surprised at how well they both shot it. Add a 55gr fmj, the most common AR ammo used and take it up to 75 and 77. This would not be an advantage for either twist rate but would put them basically on the same level with no advantage to either one. I personally feel the lower weights are for .223 bolt action rifles with very slow twist rate 1-10, 1-12 and really are not meant to shoot in either AR style rifle. I do congratulate you on your endeavor and really want to see the real world data from extended usage. Thanks

My bet is that we will see very little difference between the two. It will be interesting to see how the melonite holds up against the chrome. It will be interesting to see if the 4150 CMV barrel lasts any longer than the 4140 barrel, under semi auto use. It will be interesting to see what difference the semi auto BCG and carbine buffer make vs the heavy buffer and full auto carrier and heavy buffer of the Colt, and how long those buffers, springs, bolts, firing pins, etc. last.

I doubt we will see very much difference between the two at all, but as you said, it remains to be seen.

Wow, haven't checked in on this thread in awhile, this has turned into a cluster****, lol. Bound to happen I suppose!

Matthew, keep up the good work brother, I can't wait to see how these two rifles hold up as the round-count climbs.

My apologies for not offering a more detailed description of Winchester Q3131. It is a 55 grain FMJ designed to meet milspecs for M193. My Q3131 is older than my Federal Lake City M193, and we shoot older ammo of a similar application first. We have an order of Hornady 75 grain and Black Hills 77 grain Match pending.

Sunday evening, we had several experienced shooters try 4 different rifles with populer AR triggers and rate them 1 - 10. Here are the average ratings:

Colt 6920 stock trigger................ 4.0
Bushmaster with ALG ACT............5.7
M&P 15 Sport stock trigger...........6.3
Bushmaster with DPMS 2 stage.....7.8

Trigger feel is very subjective. I believe that before buying a Rifle, one should try that rifle's trigger for oneself.

I have seen and heard of at least 7-8 Colts blow up over 4 decades. Colt is not the best made or the final word in AR's.

I'm not a COLT fanboy by any means, but by your accounts, 1 COLT blows up every 5 years. To me, that's an EXTREMELY well made product.

And OP, is that bench rest shooting or standing off hand with those results?

How bout the WHOLE story?!
Every AR I have ever seen that had "blown up" was an ammo induced failure.

He has it in for Colt. He has been asked for proof in other threads but doesn't deliver.

I mean, I could come up with anecdotal failures for many big name manufacturers and the lists would be high for everyone. I would bet money, however, that Colt would certainly not be near the top.

This is the equivalent of saying guns kill people. It’s only half the story. Kabooms are caused by ammunition failures, an overcharge of powder or a squib load followed by a full power load.
