EMG Helios Sharps Bros. / SLR Rifleworks Licensed MB47 SOLO Airsoft AEG (Model: 5.4" Handguard / Add Kestrel MOSFET)

"THIS GUN IS NOT 11.1 READY the piston has all plastic teeth and got chewed up after about 4 games the air nozzle is also a very cheap plastic and is not very secure in the gun. However the externals for the gun are wonderful and it has great rof, range, and is very accurate. If you get it on sale for 200$ like I did then yes this gun is fully worth it but I would not pay any more then that. I had to upgrade air nozzle, cylinder head,and piston and im adding a MOSFET which came out to about 70$

"Pros:
Externally looks and feels good
Good materials
Battery space

Cons:
Dytac Quality control on gearbox is terrible
My gearbox was warped, causing poor meshing with the gears
Sector gear broke after a day of use, likely due to poor alignment
Gearbox was incorrectly assembled ootb, terrible shimming, bad greasing
Outer barrel was incorrectly aligned, causing air leak around the nozzle by pulling the inner barrel away, fixed by shimming and rhoping for a good airseal

I ended up upgrading the internals, because I love the externals
We put a complete built gearbox inside, after some milling, worked well.

External - 4/5 good build, potential issues with misalignment
Internal - 2/5 poor quality control by dytac, pretty sure i got a lemon
