My preban Colt Sporter II is moving on to a new home. Several shoulder injuries have made it hard to hold and therefore shoot a 20 inch barreled AR-15.
After attending an Urban Warfare Shooting Class a few years ago, I got rid of my first AR-15, a Colt 20 inch R6600 HBAR AR-15A2. After firing roughly 1000 rounds in three days, I was exhausted. I had purchased that rifle specifically for that training course. And during the course I learned a lot. The main thing I learned was that rifle was damn heavy. Immediately after completing the course, it hit the gun locker and remained there until I found a buyer. After the course I also immediately bought a Colt 16 inch lightweight Ar-15A2 upper on a Colt AR-15A3 lower.
The above preban Colt 20 inch Sporter II came to me from one of my brothers after I got my lightweight and has sat unfired in my safe ever since. A spring episode of "gun fever" caused me to decide to turn an unused asset into something I could use. For a microsecond I thought about an AK 47 but I just couldn't do it. Maybe next time.
The base for the replacement will be this lower from Rock River Arms.
I am presently working out the details for the upper receiver. At this point, I think it will not be an A2 style upper. It will however have a lightweight 16 inch chrome lined barrel. It will also more than likely be made by Rock River Arms.
I think a lightweight 16 inch barrel AR-15 with any sighting system (red dot, telescopic or iron sight) is very effective up to 100 yards. If the person you are engaged with is 100 yards away or more, I feel you may want to consider withdrawing or it's probably time for a larger rifle.
06-03-10, the lower is now in my possession.
06-08-10, my upper has been ordered as shown her. This is an Rock River Arms Entry Tactical Upper Half (A4 Receiver)with a detachable A2 carry handle. The lightweight chrome lined barrel will be 1/7 twist.
Assembled, the new rifle complete with a full 30 round magazine will weigh equal to or less than the Colt Sporter II without a magazine that it replaces.
