Haven't posted any build stuff lately, but I've been working on quite a few lately. Tonight I am showcasing my two highest performing replicas along with my plate carrier and alice pack.

On the left, I have a modified Classic Army Magpul MOE M4. Externals are completely stock aside from a new upper receiver in order to replace the previous one. The CA Magpul M4 uses a split upper receiver which is a pain to work with, and aren't very durable. I've added an HK rear sight since I like that style of sight. Removed the muzzle break and added a Noveske Madbull amplifier(I love their sound and use them in many of my replica builds.).

Internally, I have installed some health upgrades.
Prowin Hop-up
Prometheus purple bucking
Prometheus purple nub
Systema Anti-reverse lever
Systema Area 1000 Tappet Plate
Classic Army stock High-torgue gears
Classic Army Ball Bearing Spring guide
Custom spring
Classic Army high torque motor
Madbull Full metal rack piston
Sorbo piston head
Sorbo Cylinder head
SRC Aluminum Nozzle
ORGA 6.23mm wide bore inner barrel.

Setup chrono's at 350 fps at around 27 rounds per second.

On the left, I have my Classic Army M15A4 which I have shown previously. This one has been polarized. This means that it no longer uses a mechbox like conventional AEG's and now uses the PolarStar fusion engine. This product uses a hybrid pneumatic/electric system. That means, the fusion engine itself runs on compressed air while the FCU(fire control unit) is powered by a battery. The FCU allows for programmable fire rates and burst fire modes, and also allows the replica to work like a closed bolt system. I have my setup to do a 5 round burst on full-auto with a rate of fire at about 21 rounds per second. I have a 62/3000 psi tank for the compressed air. This build is a large mish-mash of externals. The upper and lower receiver are stock Classic Army post '09 production as well as the outer barrel. Stock is a crane stock from a G&G Combat Machine Raider. It has a Daniel Defense 9.5 inch rail along with a Magpul AFG. Pistol grip is Magpul MOE. And of course, I have the Noveske Amplifier.

Internal upgrades:
Polarstar V2 fusion engine with blue nozzle
Prometheus hop-up
Prometheus purple bucking

Both replicas built by me.
