I got it out of 10 day DROS jail yesterday, and took it to the range today. I was shooting IMI 77 grain. OTM MK262 MOD1. Using the carry handle iron sights. first I was breaking clay pigeons on the 100 yard berm, then I was smashing the pieces of clay pigeons with subsequent shots. With the factory H buffer, the MK262 did not seem to have any harder recoil impulse than M193 55 grain.
It was absolutely dead nuts on. Of the 6 weapons I took to the range today, it was the absolute "Show Pony" of the bunch. This is from a time when Colt meant quality, and everything in it is Colt made.
