My Polar Star Build is near completion. I tested it out at the Fightertown Fund Raiser Night Game. Worked Great!
I spent several months slowly building this rifle. Countless hours designing the custom parts. Had to do a fair amount of modification to the receiver to make everything fit and run my wires to the buffer tube. I think it all paid off though.
Madbull JP Industries Receiver
Madbull JP Industries 9.8" Handguard w/ Barrel
Madbull JP Industries Upper x 2
Madbull Novesker CQB Outer Barrel
Madbull Daniel Defense 7" RIS
Magpull PTS Ergo F93 Buttstock
Magpull PTS AFG2
Polarstar Fusion Engine
Redline Grip Connect
9" Foam Filled Silencer (bought from Redwolf quite some time ago)
The FCU and Battery fit in the Buffer Tube:
Custom Built Buffer Tube Cap (Original needs a screwdriver or coin to install/remove):
Custom Built Continuous Upper Rail:
Custom Built Buttstock Spacer (to create smooth transition between body and buttstock):
1/8" 90 Swivel Fitting runs hose parallel to receiver, and allows hose to swing left and right. Keeps hose from kinking or getting in the way when laying gun on Bipod:
2 Uppers, same lower. /\ AK length Barrel \/ M4 Length Barrel
I still need to do a little bit of work to the insides of both Uppers to allow the imitation bolt to slide smoothly. Apparently Madbull felt that a "bolt" was not necessary with this upper, seeing as how the charging handle does not even have the required catches to grab the "bolt".
