Hadron H plate pictured alongside the Mk23 Hop Arm

New product, the Hadron Airsoft Designs H plate, designed to fit under the hop arm of the Mk23. ASG, STTI, and TM. Works best with the TDC V2.

The H plate increases the pressure on the hop rubber, using a custom designed concave pattern on the underside. The H plate sits in a self centralised position. Check the build guide sections for fitting instructions. ( Mk23 Hop Arm NOT INCLUDED )

Best suited to an OPEN windowed barrel.

    Allows me to use heavier weight bbs, thus allowing greater range and accuracy

    Highly Effective

    This is super easily installed. Took me 3 minutes with a screwdriver. Combined with the TDC dust cover, I can easily hop .50 gram BBs. If someone made .75 gram BBs, this thing could probably handle them just fine. Great value, probably the single least expensive upgrade with the highest benefit in existence.

    Works very well. Is somewhat flexible but has no sharp edges that could potentially harm the bucking. Has a nice groove that molds to the circular shape of the bucking, it is not visible from the photos but it was a pleasant surprise. Works very well with the TDC dust cover.

    Between the i and the h the h uses less hop to achieve the same/better ranges. Because of this i also noticed a small fps gain vs using the i key. I highly suggest this part with a maple leaf bucking you will not regret it.

    Awesome upgrade, especially in conjunction with the TDC cover turns a MK23 in to a sniper !

    Awesome piece of kit, well worth the price, it will stabilize the BB's flight by keeping the correct amount of pressure on the hop rubber. definitely recommend this to anyone with a Mk23.

    H Plate by Hadron Airsoft Designs

    Small but mighty! I can say it was easy to install (having no prior experience in any Airsoft modification ever) took seconds to slide into place with the hop unit slightly relaxed and was in use within 10 minutes of the package being opened.

    The H GOD

    My lord this insanely tiny piece of plastic (if we can call this godly invention plastic?) Is absolutely fantastic. Helps apply pressure on the hop and to say it's noticeable is an understatement. Ridiculously happy with how well it works. Would Definately recommend getting one.
