That's not even real blowback. It only goes back like half an inch; plus it's like $400(out of my stock gun price range). For example, is there anyway to buy a kit to recreate the type of blowback on a Army/G&G L85 or is that impossible. I want to know because I plan to buy a SR-25 (not soon) and I wanted to know if they made any kits for them because I believe they made a blowback kit for the Star L85.
