At present I am using Troy BUSI's front and rear and a Trijicon Reflex witha 4' MOA, works fine for me.
You may want to take a look at the A.R.M.S. 40L or LP to go with your Samson front, this combo works good for me on another setup that I have.I have a Samson Flip sight front, and a Yankee hill rear. Not totally satisfied.
My problem is not with the Samson, but the rear sight. I have been thinking about a Wilson rear with the adjustable elevation as well as windage. Any experience with this sight?
I do like the co-witness capability allowed with the AR sights and such.
I am open to others experience and opinions.
There's no batteries in the ACOG so nothing to fail unlike the red dots on the market like EoTech or Aimpoint. If it falls off (hard to imagine why unless you didn't tighten the mount) you just flip up the sights and keep shooting. If you're so close you don't have cover or time to flip up the sights - why would you need the sights anyway, just point and spray. The only other scenario for it failing would be to be hit with a shot fired at you. At that point, worrying about BUIS probably isn't the biggest issue, taking cover and getting the hell out of there would seem to be the highest priority.One question..... how is the BUIS functional with the ACOG ? I guess you have to call time out and remove the ACOG if it should fail.
I'm joking about that but seriously...what do you do ?
