Here are the hard numbers from the previous mechbox test using an M150 spring and the 10.44: DSG 304.1 FPS 38 RPS (derived from Audacity audio analysis from video clip) 23.9 Amps continuous Some may argue that this ROF is abnormally low for a DSG but as the initial goal of the build was the […]Read more "HK416 Build – Experimenting with alternative setups"
Had a few minutes before making dinner so I threw this together. I originally had the Tienly 30k motor in, but with some storage-voltage (11.4V) buffer tube lipos, it wasn’t cranking the gun well enough as I’d like, so I swapped it out for the ASG U18000. Overall I’m happy with the very consistent, low […]Read more "HK416 Build – Updated mechbox functional test"
Use of the dual-sector gear requires trimming the height of the tappet plate such that it will return the nozzle for the 2nd half of each rotation. As it has been several years since my last DSG build, some other critical steps were forgotten and the results were…interesting. Note that the unusual wear pattern on […]Read more "HK416 Build – Required modifications"

JL dropped off his gun last week for a routine maintenance check-up and to swap out his BTC Chimera to a Spectre prior to Nightfall 5. What started off as a standard VFC SR16 CQB Master was shortened down to a 10.3″ barrel and a DD MK18 RIS II replaced the URX II. At the time […]Read more "Standard Maintenance and upgrade to Spectre"
I built a complete BCM KMR SBR for DS a while back and he had received the ASG Ultimate U-18000 motor due to its superior high-torque performance. However, after a few milsims, he brought it back, noting that the gear whine is higher than normal compared to his SHS HT/SHS 13:1 setup. After checking the shimming at […]Read more "Motor Comparison – ASG Ultimate v SHS High Torque"
