"Review for Specna Arms / Rock River Arms Licensed EDGE Series M4 AEG (Model: M4 Pistol / Black SA-E18)

Price paid $239 USD

Cozy little replica. Shoots ~300fps w/ .32 out of the box (roughly 1.32 joule), rate of fire is roughly 20-21RPS with an 11.1 Li-Ion 3000mah 16c Titan Battery. Accuracy is good as the replica is meant for short range, probably 125 feet or less. You can hit targets further than that but the intended purpose of this is obviously CQB based on the size. Hop up is easy to access and adjust, and holds during shooting. Gate X ASR works fine and doesn't heat up to repeated shots on semi.

Internally, everything was great. The Bevel and Spur gear needed some additional shims as they had 0.5mm of play. The only negative about the internals is that the spring guide is cheap plastic, but that shouldn't have any bearing on longevity or performance. Motor height needed adjustment by about 1mm pushed toward the Bevel gear.

Disassembly is painful, but you should only have to do it once for the reshim/cleaning. There is nothing noteworthy to need upgrading, 20rps is fast enough trigger response. Only meaningful upgrade would probably be Flat hop or Rhop as the stock barrel is already 6.03mm. For something that costs $239, it is probably the best value out of the box replica there is.
