MC Operator




Hi all... first time poster.

I recently got a MC Operator but want to clean up the rear sight, not a big fan of 3-Dots. I'm running 10-8 on my Glock and loves them and want to do same on my MCO.

My question is which notch should I can that will fit the facotry OEM night sight front dot. Brownells has three different notch.

Standard - .325 high with following U-notch:

.125
.140
.156

Opinion?

Thanks,


~dpc

The notch is the width of the rear sight opening so you can choose what you would like. .140" is the most common.

.325" I think, is the wrong height for Springfield, I believe they use .375".

Standard height 10-8 rear works on 5" Springfields. The .375 height Plexi is referring to is the measurement on the "tall" rear that Springfield uses on Ultra Compact sized pistols. The .140 U notch is the usual one every job we've ever done gets spec'd with.

To review: Standard height rear with a .180 front sight on that gun usually bore sights dead on.

We have done two of these for cttbax on his MC Operator and his SA Professional.

Measure your rear sight properly. My MCOP required a .375" tall.
