My first AR a few years back was one of the restricted LE6920 models, wrapped and new in the box. I ended up putting a different hand guard, an Atlas bipod, a Giselle trigger, a folding Larue Troy rear sight and a Leopold MarkAR scope in quick release mounts, so it doesn't look at all like it did originally. These modifications leave you with a lot of spare parts in a box. It does always go bang and seems very reliable and shot into the 9 ring at 25yds straight out of the box. I've gone out with a few guys with other new AR's that weren't even on the paper at 25yds. Maybe today I'd consider one of their stripped models so I could dress it up nice, which would be cheaper than swapping out the original parts. I have noticed, though, that despite all the cool toys available for AR's that if you look at a lot of pictures of swat teams and spec ops guys, they very often are carrying pretty stock looking M4's with the original hand guard, Aframe front sight and often the older original Armalite M16 style with the non removable carry handle. There are even a lot of the solid stocks still being used, A2's, I presume. Lesson is that the Colts are a pretty good weapon of war...and of play and I don't think you can go too wrong buying... and relying on one in a bad situation. That being said, my second AR is a 10.5" pistol built on an 80% lower and Anderson upper, which is a very very fun little gun. Unlike the Colt however, the upper had to go back to Anderson for chamber work that was causing stuck rounds. When that happened, I knew I had done right by first buying a stock Colt, which I will never for one second regret.
BTW, I love this forum. Whenever I have an issue I can come on here and always find the answer. Many thanks to all of you more experienced AR guys.
