- Updated Flex Connector. More parts, but addresses printability, durability, and installation concerns. Uses 1x of the same springs found in the stock latch and e-port latch.
- Adjusted laser button geometry to be more tolerant and increase button press travel distance.
- Changed upper receiver and charging rod adapter- made the rod adapter captive within the upper so it doesn't fall out constantly. Old model can be found here if you need it.
- Updated LCD graphics to be perfectly inline with the display face outline
- Reworked decals art, only slightly (added more custom options)
- Added chamfer to magazine body so it doesn't get caught on the little "bumper" plate.
- Added new feed lips and follower geometry (Thank you White Rice!)
Tolerances:
- Updated safety geometry tolerances so its less sloppy
- Updated Compass Lid tolerances (bolt holes only, non-critical)
- Updated Compass Mount tolerances to fit on the rail a bit better
Geometry:
- Updated Display Armor geometry so it can be slid on/off without taking off the middle cowling
- Updated battery door to be more accurate to in-game model. Backwards compatible.
- Updated flashlight cap to be accurate to the in-game model. Backwards compatible.
Build:
- Removed printed gas tube plug in favor of a (metal) sleeve bearing.
Hardware:
- Added flex connector geometry
- Added display "wheel" geometry
- Updated main power switch geometry
- Slight update to display base to support final assembly with wheel. *If you have a prior display base model, simply cut the back half of the dovetail slot so the walls are vertical.
- Aesthetic updates to the display housing
- Aesthetic update to the grip module
- Tolerance update to lower receiver (flex connector bolts)
Electronics
- Updated to new revisions, fixing silkscreen
Firmware:
- Updated round counter logic to account for the state of the chamber, which corrected an "off-by-one" error.
Docs
- Updated BOM for hardware to include new parts for the electronics suite + earlier corrections
- Added finalized (smart) magazine geometry
- Added electronics BOM
Gas Port
- Added little notch to HG top mid which should stop the gas port plug from wiggling out of place over time.
- Updated gas port plug. Its a big longer now.
New Display Housing
- Added display face geometry
- Added display LCD backing geometry
- Updated display main housing to fit new display face
New Button Board
- Updated HG - Front Bottom to better fit the button board. If you have the old design still, you can drill out a small channel for the top wire to be in, or melt a little slot with a soldering iron.
- Updated flashlight button geometry to fit new button board.
- Updated compass mount to fit new button board.
- Updated laser button to fit new button board.
Misc
- Updated Barrel extension. Removed the need for the panel nut and nut cover, but added a new link to the thread adapter used. If you still need that old panel nut, its 1/2 x 28 and 1/8" thick.
- Aesthetic update upper handguard sections (HG, top front & HG, top mid).
- Updated E-Port housing to support a better, panel-mounted switch
- E-Port box now fits and matched to finalized E-Port circuit
- Updated Power switch to match finalized E-Port circuit
- Updated tolerances of a lower bumper for easier fitment
- Added safety/FRT plugs
- Added preliminary display housing
- The MA40 is now compatible with cam/lever style forced-reset triggers. This was a geometry change to both the upper and lower receiver
- Updated gas port cover geometry for an easier fit
- Fixed a regression where the wire channel on the lower receiver was broken / blocked
- Updated the trigger linkage so that a shim is only required if you order the SCS metal part. The printed linkage no longer requires a shim
- Added troubleshooting and FAQ sections to the build guide
- Added documentation for PCBA of custom electronics. Good luck!
- Updated cheek pad to accept a standard AR-15 dust cover
- Added decal guide
- Updated Upper receiver to host dust cover a bit better
- Updated trigger geometry to only require 2 bearings while also better securing them. Should prevent them from falling out over time
- Swapped FCG bolts for dowel pins. If you need the old M4 bolts for any reason, they're here.
- Changed geometry of lower receiver- added notched cutout for milspec trigger. This fixes issues where the disconnector wouldn't fully release/reset after releasing the tigger.
- Added 1mm extra length to the safety so the detent engages more reliably.
- Added 38mm dowel requirement to fix dowels that might walk out over time.
- Corrected lower receiver FCG pin placement, which should help alleviate some firing and charging issues.
- Updated laser module housing so the tip matches the game's geometry more closely.
- Updated top electronics "conduit" to not rely on another heat insert + widened the actual conduit hole.
- Added laser button
- Added terminal / housing for 18650 batteries
- Corrected build guide step order for trigger / mag release (trigger install must come before mag release rod)
- Adjusted tolerances for mag release rod
- Added preliminary compass/laser housing
- Added preliminary decorative wire conduit
- Modified upper receiver geometry (back plate area) for increased strength. If you have already printed the upper, shaving off the space for the new back plate fillet with a razor knife is possible.
- Added missing "Gap Fillers" files
- Updated tolerances of stock plate bolts so the bolt heads don't stick out.
- Added preliminary laser module housing
- Added a sleeve to block the gas port.
- Added printable decorative dowels for handguard.
- Added printable safety selector.
- The flashlight is now printed in two pieces and has a proper screw-on cap. This change also removed the O-ring requirement from the BOM.
- The grip detent hole has been significantly widened for easier installation/uninstallation.
- Added a printable shim to the trigger linkage to prevent it from jiggling out of place.
- Removed 3/32 dowel requirement (replaced all with 1" 3/16 dowels). Affects all handguard parts and the side plates.
If you still need the 3/32 dowels, find them here.
This is the first semi-public release of the project. Check back here as bugs are discovered and fixed!
