| I'm looking around for a rear sight for my A3 flat top. Many of you have good things to say about the ARMS #40 unit. Any of you have experience with the DPMS #FT-RS? I'd be interested in your evaluations of fit, reliability, function and strength. And thanks in advance for your help. |

Will you be using your rear sight with any type optics and if so which one(s)? Some of the Knights products are a little lower than the ARMs #40 to fit under the scope. However, with the KAC 300 meter sight you get one distance to zero your sight compared to the ARMs #40 havign two and a half (I only count the little notch for 500 meters as a half). The KAC 600 meter sight is adjustable for distnace (if you are shooting at under 300 yards not an isssue) but you loose the larger apperature, which is an issue under 50/100 yards for any type of faster shooting (be it matches in my case or real world tatical for the LEO and military). |

I've had both styles, and for my preference, it depends on what you're putting in front of or over it. For a red-dot sight, I PERSONALLY (no flame if you like it the other way) prefer full function A2 style sight like the DPMS or even better, KKF chopped carry handle (never had an LMT). The latter is more robust, gives you the choice of type of elevation wheel, and takes up less rail space. Although I have wondered how a DPMS rear would fare if you cut off the forward half inch or so and made it a one-screw job... I've had 2 DPMS rear sights. On the first one, both screws were machined flat. They did not interface with the slots in the rail so you could position it anywhere on the flat-top. This latest one has both screws left intact and they each need a rail slot to fit in. I wonder if those broken screws were the older style like my first one. Screws with half of their post shaved flat can't be that dependable. Now if you're going to use a magnified optic, then fold-down is the only option. I have only owned the #40, so I can't give opinions on any of the others. |
