Nice basic AR15 rifle, genuine Colt, the original. Extremely accurate right from the box with iron sight and Magpul pop-up rear sight.
Flawless performance so far. Very pleased. Only minor glitch: Buds description says 30 round mag, received with 20 round mag. Buds made it right and I purchased 2 extra Colt steel mags and 2 Magupul plastic mags. Rifle shoots fine with either.

Ok....Call me biased, but I'm a Colt man. Have been since 1976 when that sweet Pony flavored Kool Aide first quenched my AR and 1911 thirst. When the 6720 came on to the scene, it sounded like the best of the old and new. A flat top 6920 upper receiver and a lightweight 6520 barrel. The 6720 is the lightest A4 configuration AR I have gotten my hands on. As a CSR at a large firearms store and range, as well as a small arms armorer I have and do handle every product on the market. I couldn't wait for our normal distributors to show availability on the 6720, so I placed an order with Buds (my first)... Seamless payment and shipping and a beauty 4 digit serial # rifle. Topped with an Aimpoint CompM3 it owns our 100 yard indoor range. I can hardly wait until the next Carbine class, this old timer is going to tear it up with this super light fast handling Colt.

Remember, Colt AR15s have a Pony on them, the rest are just copies of the real deal.

Thanks for the assist Buds! Well Done!

This is about my 9th flawless transaction with Bud's. The M4 Style Colt LE 6720 came with the Matech BUIS 200-600 yard sight, as the military is currently adopting. Also, were 2- 20 round mags, cleaning kit and sling. It weighs 6.3 lbs w/o a mag. One of the deciding factors, as an avid 50 year shooter, was the pencil barrel, which gives it a 'perfect balance' with better control on follow up shots. I put about 240 rnds of Silver Bear 62gr, 55gr Green Tip penetrators and 55gr PMC Xtac FMJ with zero malfunctions. The action was like butter and fieldstripping, cleaning and reassembly was a 10 minute deal. Accuracy was only limited by my ability. The flat-top upper has a numbered rail for an optic and I am considering a scope or red dot to increase its versatility. The 4 position stock is great, but I only use the fully collapsed/extended positions. Action is gas impingement which I believe is better than the piston type. I didn't use the 20 rnd mags as I keep 30 rnd composite Magpul Pmags since they can be stored and transported 'loaded', without acquiring dings or distortion the the mag lips, etc. The trigger was clean and crisp. The 7 inch fore grip is double insulated and seems a tad short, for me, but not enough to change it. Some would surely prefer a quadrail for lights, lasers, etc., but that is a minor expense. This carbine is a complete joy to shoot with its excellent balance and light weight. The 20 round mags will definately get used for sighting in and hunting varmints as they fit well on a benchrest. It took a few hours, but this carbine became my absolute favorite over my other quality ARs. The Colt quality is immediately noticeable. With proper care, this Colt 6720 carbine should last a lifetime and still be worthy of passing down to another generation. Others may choose the model LE6920 with the heavier barrel (with cutouts), but it is not my personal preference. Being able to avoid that 'front-heavy' issue on an AR is a major accomplishment, to me.
This carbine is a gem and is as close as a civilian can get to Colt's actual military MilSpec M4 issue. It is easy to see why the military is adopting the M4 as its new standard military issue. Colt is the real thing. This would be a great choice as one's first AR or any experienced shooters upgrade.
I highly recommend this carbine.
