I have basically settled on buying another Aimpoint for my 2nd M4. I have an Aimpoint Pro on my Daniel Defense LW M4. My other AR is a S&W M4 with no optic at the moment. I have 2 options if I stay with Aimpoint. 1. Put an Aimpoint Micro T1 on my DD for 650 with a Larue QD mount included that will really go well with the lightweight DD rifle, and put my Pro on my S&W. 2. Buy another Pro for 360 mount included, and have Pro's on both my M4's. Kinda boring but practical. I love Aimpoints, and saved up to buy the DD M4 as my dream rifle. The T-1 is my dream sight to go on the rifle, but is it worth 300 more dollars which is near double the price of another PRO. I have the money right now to do either but buying the T1 would wipe my gun account out for awhile but would have a super LW setup on a LW carbine. Tough call! Opinions please.
