I recently bought a new Cyma CM045 for around 70£. So far I've done some preventative work (reshimmed and relubed everything, checked seals etc). All I changed was add an R hop and mosfet. The gun is very quiet now (around 82 decibels) even though its shooting 1.65 joules (local European limit is 1.7) Suppressor really makes this gun shine. Stock motor and gears give just under 20 rounds per second which is enough for me. Effective range is around 65-70 metres with 0.32g bbs. The sight rail is just a diy from left over rail that's bolted onto the dust cover. Overall a great replica that's highly durable and upgradeable
