I honestly don’t understand why these are popular with some people. They are heavy and way overpriced with so many options being better on just about every level. The Gen 2 added an M-lok handguard as an improvement over the first Gen ACE’s bulky plastic offering. Unfortunately the handguard is heavy as hell and you’ll end up replacing it if you decide to keep this gun on a serious level. The trigger is also crap and makes a WASR feel like match grade. Supposedly ALG will fit but again changing out parts. No sights on Gen 2 at all so you’ll be dishing out more $$$$ on top of the 3x this gun is worth.
