a nearby indoor shooting range designed to handle the 5.56x45mm Nato load, I am back to owning two models of the AR-15. I've had the Blue Label Colt HBAR Match Sporter since circa 1993. The one AR-15 I ever regretted selling was a Colt SP1 Carbine; I found that I like the above civilian M4 style carbine far more than I ever did the SP1 Carbine, so my universe is back in balance.
Will I be buying any more AR-15 models? I doubt it, but it is always best for me to never say never.
In the photo above, the six-position telescoping shoulder stock on my new carbine is shown all the way in, creating a very compact package for smaller shooters (as well as for easy carry and storage).
On rare occasions I will do some fast-blasting using the standard capacity AR-15 30-round-magazines; it is darn good entertainment but I am too cheap to make a habit out of it. During most of my range time I stick with S L O W fire using the lower profile old style 20-round-magazines. The mags in the above photos are actually Colt's old factory 5-round politically correct mags (permanently reduced-capacity 20-rounders) from the early 1990s.
