G&P Mechanical HPA Powered M4 Airsoft Rifle (Length: 10.5" Keymod Handguard / Black)

"First impressions
The engine is the same as the lancer tactical legion, oem is milsig, not necessarily an issue in itself.
Externals are nice where it's aluminum, decent enough for the polymer parts.
Velocity adjustment is a tiny allen bit on the bottom of the asa
I got the 14.5 inch and it's noticably lightweight.
Picky with mags, going to try an ics hop unit to see if that helps.
Rof is good
Velocity is around 1.6j out of the box with no hop applied.
The lack of instructions was annoying but if you're the type of person that can't leave anything mechanical alone you'll be fine.

In short I'm optimistic about the replica and any issues I've come across so far should be fairly easy to get around, I'll add to this after I field it in a couple weeks.

"Alright, how should I start off.
This gun is great out of the box, although I was a bit disappointed to find a could of polymer components on the gun. The charging handle and the imitation bolt release are both polymer.
On my model, I had a problem with the imitation bolt, it would get stuck and I had to use my finger in order to move the plate out of the way to adjust the hopup.
The hopup on the other had was very disappointing. I would get no “hop” out the unit. I tried fixing that problem, but couldn’t get it to work. I’m to the point on swapping out the hopup unit for a new one.
The tigger response is pretty snappy. You can lob bb’s down range pretty fast. Full auto is pretty high for a gun that doesn’t require and FCU. If y’all have any questions, feel free to contact me on Itsjustthemorning on Instagram. I’m happy to help y’all if you’re interested in getting this gun.

"My review will be on the G&P Mechanical HPA Powered M4 Airsoft Rifle (Length: 10.5" Keymod Handguard / Black)

Pros:
1. Solid aluminum construction, fit and finish are excellent with no movement between the upper and lower receiver or the rail system, Outer barrel does not move and is held in place perfectly.
2. Good RPS and trigger response, trigger feels like a gbbr trigger with a noticeable reset after each shot.
3. FPS is 390 with .20g bbs and a 13/3000 psi tank
4. All mechanical so no need for battery’s!


Cons:
1. For a $480 gun packaging is VERY basic, basically you get two foam pads top and bottom for the replica to rest on. The gun is wrapped in bubble wrap (gun is not held in place and is free to move) and the other stuff just thrown in a bag and tossed in the box.
2. There is no manual so good luck finding out how to adjust your FPS or do maintenance.
3. The replica seems to only like to feed with the included G&P 130 mid-cap mag.
4. Replica uses an old school dial hopup unit and has minimal adjustments for dialing in your hop.
5. Not sure why but the rail doesn’t seem to be key-mod but more like M-lock due to it having slots like an M-lock rail.

With all that said still a great gun overall and shoots flawlessly, the cons are mostly with the packaging and little stuff not necessarily the gun and how it performs. Your results may very from mine as not every gun is 100% perfect.
