    Sorry. The BCM rail sections and the KAC QD mount use a different method to implement the counter recoil part of the design, which is why I was confused. BCM & KAC essentially utilize a lug that drops into the larger, rear part of the key

    Same here. I suppose there must bo some logic in passing on the recoil tab... seems to defeat the purpose though.

    That tab essentially serves the same purpose as it stops the mount from being pulled backward and the footed nuts stop it from moving forward.

    I guess I'd have to play with it to understand. I'm far from a keymod expert... so I'm just used to the way the OEM stuff mounts.

    (I see now... their tab grabs the back of the next key slot over. Silverbullet's pics make it clear to me.)

    hopefully this clears some things up. If I missed anything please let me know, today is daddy and Davi day so I did all the photography and write up while holding, feeding and changing dirty diapers of my four month old daughter.

    Well I decided since I can tighten until the mount has very little play where I can insert and removed the qd, that I am just going to use some blue loctite on the bolts for the mount and reattach it. Once I insert the qd it loses the very little play it has. I am confident I will have no issues even without the blue loctite. Thanks again Earl. I am a happy customer.

    Endur, Thanks for all the info you provided yesterday regarding the issue with the alignment. It really helped us dissect the problem and gave us the opportunity to audit our complete quality system, from design to manufacturing.

    Even though your satisfied with your part, I'd like to send a replacement we've confirmed is to spec and get yours back for analysis. We make the mount, but purchase the KeyMod feet and fasteners for all our KeyMod products from a supplier in the industry which makes KeyMod rails.

    We stopped CNC production about 150 parts into our current run to verify our SPC measurements were to print. They were. We also measured current inventory as well as the samples we keep from the first and subsequent lot and they all were within the +- .002" tolerance we designed of a critical measurement, the one that aligns the hole in the mount with the hole in the keymod rail. Kincel's published spec's may be used by everyone making KeyMod rails, or may not be, but we hope so. The challenge we've faced since we launched four years ago is making IWC parts fit other peoples parts, without knowing what range of dimensional tolerance they hold, or if they change their product after we make and launch ours. With this in mind, we have to build in tolerances to accommodate a varying unknown range used by other companies. We have .015" tolerance built into the measurement controlling hole alignment between the rail and our KeyMod Mounts we make; Light, Bipod, Hand Stop and QD Sling Mount. In combination with the feet, so far, this range has worked across all the mounts we've sold. The Sling Mount is the most critical, as hole alignment makes it function as designed. SilverBullet's pics and other's commenting in this thread, along with the ton we've sold are a good example of how the part fits. Yours experience is not.

    So we would like to have your part back to evaluate. Please email me at: earl@impactweaponscomponents.com. Thanks again, really appreciate your assistance.

    For the record my experience with M&S product installation could not have been easier or more secure.

    I was having the same issue with the IWC mount on my KMR rail; QD not fully seating. I originally installed the IWC mount, as received, with the "toes" of the boots pointing in opposite directions. Once I changed the rear boot so that both the toes pointed toward the barrel the mount snugged up well and the QD works as it should.
