Real Sword AK's are amazing from what i've heard. THey shoot low out of the box but i've heard they dont need any upgrades for an M130 like spring.

 

CM.028 is $110 free shipping from airsoft gi...not the best internals but if you upgrade its still gunna be under $200

 

The Real Sword is almost double is maximum price. The Cyma 028 is yester-years news, it's complete garbage to today's selection. To the OP, why do you want to pick from the bottom of the barrelI still recommend the G&G CM line. FAR more dependable and rugged in the long run. They're around $150 at every retailer I've visited. By the way, the Echo-1 RedStar is $220+

 

Simple solution,,,all of the replica's you have listed(bar the really cheap Cyma's)are of comparable quality,,so pick the one you like,,,,if it was my wedge then id dump it on the CM048,,,,,,my local retailer had these in stock and i was blown away by the external quality and attention to detail,,,honestly he could of told me it was a VFC and id have been none the wiser.
