    MK23 SOCOM NBB TDC COVER V2

    Feels very solid, does what it was designed to do very well. It is the most important upgrade item for the MK23 in my opinion and paired with the H key it reaches out very far. I got a shot on target at 180-200 feet using 0.25 bbs

    TDC cover

    Posted by chris on 15th Dec 2017

    Fitted to hfc mk23 Super easy way to fine adjust hop easy to fit very solid design really makes a difference to hop performance, only tried with 0.32g so far which fly dead straight, using maple leaf autobot 50 degree and i key and stock barrel would recommend as well hadron H plate over I key due to better fit and half the price, if you only make one mod buy this TDC makes life so much easier.

    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.

    Wow

    Posted by Daniel Park on 9th Nov 2017

    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
