There are several variations on the Colt’s AR 15 rifle. While I have my favorites any of the Colt’s will give long service in the harshest environments. It is like the old question of do you know the difference between an elephant and an ant? An ant can ride an elephant — many companies have done the AR 15 and some have done it well but the Colt’s is still the one that all others are judged by. On that subject the same may be said in spades concerning the Colt 1911. The pistol has been first with the most since 1911. While there are high grade handguns that are good examples of the maker’s art, those that cost less than the Colt are, well, cheaper guns.

This is the author’s long serving M4.

Field Test
I elected to go a field test of these guns. You have to get down and dirty sometimes. I appreciate my firearms but they are workers. I also love my shiny near new Jeep, but I took it across the Jeep Beach at the Outer Banks. That is what it is made for.

Each Colt’s features a birdcage type muzzle brake.

The Colt’s LE6940 was good enough to cause me to retire my long serving Colt’s HBAR. The LE6940 carbine is about as accurate in practical terms as the longer rifle and carries much easier. I like it better. With a flat top, a CNC machined 7075-T6 Aluminum forging, and Colt’s quality, this is a winning combination. A chrome lined bore, four position collapsible stock and the classic flash hider are all hallmarks of the carbine. It uses .0154 inch hammer and trigger pins so be certain to specify Colt when ordering an aftermarket trigger or parts. The chamber is a 5.56mm NATO, and the barrel twist is 1-7. The barrel is .750 inch diameter at the meeting of the gas block, slightly less the rest of its length. The trigger and safety are crisp in operation. One example is fitted with the XS sights rear aperture that allows using the conventional sight picture at longer range while using the sight notch at 7 yards. The Paul Howe designed CSAT makes for great utility for home defense use. The other sports a Redfield Battlezone optic.

The Colt’s collapsible stock is a good feature.

Firing Test
I fired 80 rounds in each rifle, firing from 25 to 100 yards, firing at quickly as I could regain the sight picture. The iron sighted rifle was by no means hopeless at the longer range but very fast at close combat range. The scoped rifle is a joy to fire and use at longer range. Both rifles, using PMag magazines, were completely reliable. The rifles have been fired extensively but this was the first outing with SIG Elite ammunition. The combination proved a happy one. I used the SIG 55 grain FMJ loading with good results. There were no function problems of any type.

The author really likes the XS rear sight. It is useful for close range and long range depending on which aperture is used.

The next step was firing for accuracy. I used the Sig Sauer Elite Match .223 Remington Open Tip Match (OTM) 77 grain E223M1-20 loading. This load has proven accurate in a number of rifles and I thought now was a good time to qualify its performance in the Colt rifle. I fired twenty cartridges in the open sighted Colt first. While I am not quite as sharp as I was once with iron sights I did well enough at a long 100 yards, placing three shots into groups of 1.7 to 3.0 inches. I suppose that is good enough for government work. The other Colt, with its optical sight, made things much easier. This time I realize the full accuracy potential of the loading. At 100 yards the Colt/SIG Ammo combination posted an average group of .88 inch, measuring the group from the center of each of the most widely spaced holes in the target. That is good enough to ride with.
Neither rifle was cleaned during this test.

SIG Sauer Elite ammunition gave excellent results.
