English Airgunner likes the EMG Helios Noveske N4 MWS Gen 3 Gas Blowback Rifle after testing and checking its internals. As it uses the Marui MWS system which is unlike the standard gas M4 systems uses a short-travel roller hammer to reduce wear on the bolt, hammer, and valve knocker. It also features a steel bolt lock plate to prevent common issues like bolt stop wear and accidental unlocking on the last round.

A closer look at the internals of the HK417D GBB rifle by English Airgunner. The UMAREX HK417D is a realistic Gas Blowback airsoft rifle with a strong recoil system, featuring a metal handguard with rails on all sides for mounting accessories, and an upper receiver with rails for sights and scopes.

Slow-mos are always fascinating to watch so here is a video from English Airgunner firing a Tokyo Marui MK18 GBBR fired in full auto in slow-mo goodness... "Tokyo Marui MK18 GBBR full auto slow motion - volume up. Ahhhhh the satisfying sounds of shooting steel and full auto burst fire in beautiful slow motion.

Seriously though it is oddly fascinating to watch."
