at the minute you’ve got 2 types of MP7. The gas and the AEP.
The electric guns are in my opinion crap. You’ve got the Tm and the Well which is a clone. They chrono at 220ish FPS I believe and being tiny have a tiny air cylinder so your performance is going to be lousy compared to virtually anything else.
Gas is much better. You have to my knowledge 4 options. The VFC, WE, KWA and the TM. The VFC and WE are full size 1:1 replicas but aren’t gas efficient or reliable. I had a WE for about a week and got rid.
The kwa and Tm are smaller than real steel but are the most popular two. The TM in my eyes is hands down the best of the bunch. It has a full travel bolt unlike the kwa, so it’s more realistic and has more kick. Range and accuracy are fantastic on the TM too. The kwa is slightly cheaper and has a slightly higher rate of fire if you’re into that kind of thing.
If you want an mp7 and it must be electric, wait until VFC release their new one. They’ve somehow managed to cram a gearbox inside it with standard parts that will be putting out 300+ FPS. That will be worth a buy when it comes out.
TM GBBR is king currently
