    Product Description



    - Modify recently released this brand new hop up chamber to replace the flawed M4/M16 units out there. Modify decided to take the standard design and implement their knowledge to enhance and improve many areas over the standard out dated hop up units. The hop up unit itself is a one piece casted piece of metal, the finish is EXTREMELY well done, nice, and clean. Their is a seem line down the middle of the hop up unit itself which detracts from the looks but the finish is superb and the unit itself feels very well made. The unit comes with 2, thats right, 2 hop up arms which have been redesigned with cogs and teeth for a new adjustment gearing system. The wheels and gears of the hop up unit for adjustment have embedded metal inserts and are attached to the hop up unit with o-rings which provide smooth but also sturdy adjustments, which make a drastic improvement over previous systems. 


    Exterior Quality 

    - Like said in the Overview the casting seems to be done extremely well and precise. The finish on the unit has a very nice texture, as well as a very clean look. It is almost shiny, but at the same time dull. The unit itself is very solid, and seems durable enough and with the little stress the hop up unit it is going to last. The plastic pieces of the unit itself are made of black plastic. Shiny with a little texture, most likely made of abs plastic. The adjustment wheel and gears as well as the adjust arm is made of black plastic as well, the metal insertions are gold and shiny. The giant adjustment WHEEL has a metal insertion in the middle where a screw is placed, this fixes the stripped screw problems found on the common plastic hop up units. Also, o rings are added under the wheel, as well as onto the other gear adjustments to keep them from moving out of place, but at the same time keeping some resistance which isn't to difficult to move. 



    -The hop up unit itself functions extremely well, adjustments made to the hop up are extremely smooth but sensitive. It doesn't even take a full turn to put the hop up on maximum, so making precise hop up tuning will be difficult. The unit itself paired with a Prometheus 6.03 SS tight bore and modify bucking along with a SCS nub provided 1.5' groupings at 25 feet. FPS went up. Had no problems feed Magpul PTS Pmags, as well as MAG 190rd midcaps. 



    - The hop up unit was placed inside a G&P Vltor MUR upper receiver, the unit itself fitted fine but only when the hop up was set to full. The charging handle spring seemed to hit the top of the adjustment arm, so hop up and to be set to full to move the arm down. The g&p mock bolt has problems with the hop up unit though, the Modify hop up unit was much thicker that previous units and would rub and get stuck against the cover. The portion where the hop up unit fits into the gearbox and allows the air nozzle to come in has a small protrusion to allow it to stabilize and center itself with the gearbox, it is a little to big so it tends to get stuck with the gearbox upon disassembly of the gun. The unit also comes with a metal ring to push the hop up unit forward a little, this is given to help with guns which have issues with feeding with the chamber. The included ring wouldn't allow g&p guns to fully assemble, since g&p uppers slide onto the lower receiver the ring causes it to protrude forward a little and so the front receiver pin can't be aligned correctly. 


    Final Conclusions 

    -Definitely one of the best hop up chambers for the money, I haven't held a Prometheus neo chamber yet but this is a pretty good contender. The quality and precision of the unit itself is excellent and screams out excellency. Compared to the madbull ultimate hop up unit the modify unit provided an fps increase, the unit itself also feels much more sturdy and solid and looks much better than the madbull unit. For only RM80 this hop up unit sports one of the lowest prices, but holds its spot as one of the best hop up units you can buy for the M4/M16 series.
