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"

Mechbox was re-inserted back into the lower receiver in order to retain the selector lever and pins rather than paint them separately. Sensitive areas were masked off and the entire receiver was cleaned up with rubbing alcohol to lift any oils off the receiver for better adhesion. 4 paints were chosen for the palette: […]Read more "Block2 Build – Paint and Final Chrono"
Prometheus 6.03mm stainless is used as per normal due to a current surplus in the lab. The standard R-hop is applied and left to cure. Stock VFC hop-up rubber is retained due to excellent temperature tolerance and good air-seal qualities. Hop nub is shaved to accommodate R-hop. The VFC hop-up unit is also retained due […]Read more "Block2 Build – Barrel Group"

As it turns out, A2 pistol grip is just as disliked in the real and milsim worlds. As such, these are typically swapped out in favour of grips such as the MOE, Ergo and Hogue grips. However a select few prefer the profile of the grip, with modifications to increase functionality. These two modifications include shaving down the middle-finger […]Read more "Block2 Build – Grip Stippling"
Straight-away the gun was torn down to the mechbox to see what VFC has in store for 2016. Engraved logo, red aluminum cylinder are new for 2016 and the 8mm bearings and red nylon-fibre piston were introduced in 2015. Looking from the rear of the mechbox, the Deluxe RIS II has a wiring harness with […]Read more "Block2 Build – Teardown + Mechbox overview"
With the Colt-licensed MK18 Mod1 firmly in its history books, it was only a matter of time before VFC turned its attention to its larger brethren. Also released at the same time was the FSP (front sight post) variant, which is still very much relevant in the wild. Back to the topic at-hand – after […]Read more "New Project – VFC Daniel Defense M4A1 RIS II FDE"
