I forgot about my DPMS ar with the .22 conversion . I have a Burris 5x prism with BDC on it. Illuminated reticle if I need it and a very small dot so long range targets aren't covered by the dot like the FastFireIII 3moa dot
I've got a 4x on my Ruger American and a Burris FastFire III on my Henry lever action.
The red dot is definitely faster to put on target, but the 4x is a lot more accurate past 40 yds
^^^^^^^....
That's around the same time I bought one from Woolco in Kenner. $19.95 with 2 boxes of ammo. I swapped mine about 5 yrs later for a Marlin .22 cause I couldn't find any ammo for it
Looks like this K1911..
