    MK23 SOCOM TDC Cover

    Awesome product. Super easy to install and the results when paired with the H-plate are great. Overhopping .3s with little to no hop applied.

    Easiest upgrade to do!

    Posted by Matthew on 29th Nov 2017

    This was the easiest upgrade to do to my pistol. I'm still waiting on my new barrels but shipping was fine to California. Took about 2-3 weeks to arrive.

    So i initially got an I key and 50 degree decepticon bucking and i barley lifted .3's on max hop. When I installed the TDC cover a few weeks later i can hop .4's with no hop on the wheel and the screw sitting flush with the top! I would run .4+'s with this cover on. I went from 200ft range on .3's to 300ft on .4's I can also hit an oil drum 100% at 250ft no problem. Range test the mk23 with the hopup rubber of choice then notice the difference when this is installed and you'll be impressed

    Well I had seen this TDC on you tube and though i would give it ago, I am in the USA and once shipped it arrived a week or so later. I am using a Maple Leaf 50 degree Autobot bucking with a Hadron H plate and Maple Leaf Crazy jet barrel. The Mk 23 is an older TM version and has full trades. The TDC is easy to fit as is the H plate, I am using .43g bbs and they fly straight and go completely out of sight, this is with only a small amount of pressure on the hop up arm. I am fitting the same set up to my other Mk23 but using a PDi tb barrel and i expect to get the same results. It is an excellent product and simple to fit and makes a world of difference. I would recommend this to any one with a MK 23 NBB pistol

    Essential upgrade

    Posted by Adam on 27th Sep 2017

    This is a must upgrade for any MK23 owner! Simple and extremely quick to change out, went from lifting .25g to .40g in second.

    Super contento con esta pieza, encaja perfectamente en la mk23 y hace muy simple el ajuste del hop. La impresión 3d es muy fina, el plástico de buena calidad, merece totalmente la pena.

    MK23 Hadron Designs TDC Cover V2

    Posted by Chris Yule on 15th Sep 2017

    The cover is a smart little change I would recommend to any MK23 user. Easy to install and with an impressive change in the hop performance even on the stock bucking. Within 10 minutes of opening the package it was installed in tandem with the H plate and I was hitting targets 50-60m away with 0.43g BB's.
