So after my last massive overhaul on my King Arms M4’s internals I had it running exactly where I wanted it.
Compression is great, trigger response is perfect but something was still lacking. Despite its consistency and efficiency I still wasn’t getting the range and accuracy I wanted.
Previously I had been using the stock King Arms metal hop up unit that came with the gun and had upgraded it with a Guarder tightbore barrel and a Prometheus purple hop up bucking and nub. Even with those I was left wanting.
So after the last mil-sim I decided to start playing around with new hop up units and buckings, the first of those being the Lonex Enhanced Hop Up Unit and the PDI W-Hold (both purchased from Airsoftstore.ca).
One big thing I found is that the majority of previews/reviews on both of these items are relegated to forums, so I had to dig to find player’s experiences. After hearing decent reviews I decided to pick up both the hop up unit and bucking to go through and review it myself.
Initial Impressions on the Lonex Enhanced Hop Up Unit.
This thing is solid as a rock. Built out of aluminum and zinc coated this unit is not only tough but its fairly lightweight compared to my King Arms stock unit.
In the package you get everything you need to assemble to unit (except a bucking and nub) which was a relief because I didn’t want to have to strip the dials and screws off of another unit to put it together. All of the additional pieces are well made and feel high quality.
The ONLY issue I had with the Lonex Hop Up Unit was the gap where the barrel clip is installed was not cut correctly. The section was cut to small and as a result I wasn’t able to clip in the barrel securely without filing done the clip itself (as I don’t have the proper tools for filing down the hop up unit).
After this small modification the barrel clip was able to fit and get a solid lock on the barrel without any further issues though.
Initial Impressions on the PDI W-Hold
So to begin I’d like to touch on how the PDI W-Hold differentiates itself from other hop up units. As opposed to a solid nub inside of the bucking, the PDI W-Hold has two separate mounds that raise to help center the BB. The concept is that the BB will be centered by the two mounds and prevent any rotation while it travels through the bucking and barrel, making for a more accurate shot.
While I haven’t tested long distance shots yet I was impressed by the build and quality of the bucking. It’s a softer hop up rubber compared to a Systema bucking however the two mounds within actually feel solid enough that they won’t get torn apart . Additionally the bucking has ribs along the outside of the bucking for a better seal in the hop up unit.
This upcoming weekend I’ll be testing out the new Lonex Unit with the PDI W-Hold and post the results compared to my stock King Arms Unit.
