Customers Who Bought This Item Also Bought

    Our take:  Systema is renowned in the airsoft world for their top-of-the-line craftsmanship on all their manufactured parts and products, and is also attributed with having a world-class R&D process through which all products undergo prior to making it into their product repertoire.  It's no wonder why more airsoft-enthusiasts choose SYSTEMA as their upgrade part of choice, over the many other brands of upgrade parts available.

    - Manufactured from silicone, making it difficult to be deteriorated by atomized oil grease during firing conditions
    - High threshold of tolerance against corrosion/hardening
    - Hop-Up Packing unit comes together with sleeve that keeps barrel/chamber centered to maximize accuracy and preserve a tight air-seal

    Disclaimer:  Any and all airsoft upgrade parts purchased from Airsoft Megastore will be used/installed at owner's discretion. Actual performance results depend on quality of installation, airsoft AEG barrel length, tightness of the air nozzle seal, and other possible performance-affecting factors.  We are not responsible for any damage that may occur with improper installation.  For best results, please do all upgrades at a certified professional airsoft technician/shop.

    Systema Bucking
    By: Jarrod Kiefer

    "The stock hopup bucking on my King Arms M4A1 ripped when I was cleaning some of the internals, so I figured I'd settle for the best and buy a Systema. It's more rigid than the stock bucking so it went into the hopup unit with only a little bit of silicone oil, and it didnt fold in on itself. Very good bucking, comes with a somewhat narrow barrel spacer."

    Great Systema hopup bucking.
    By: Vit

    "It's Systema, so you know it's good. Very high quality built bucking that increased my AK 74U accuracy and overall performance. Hop up bucking is one little piece that matters the most."

    One of the Best Brands, Results Vary
    By: Andrew Derr

    "I have purchased one of these for most of my guns, and here's what I found: 1) JG G3; no noticeable difference (NND) 2) CYMA M14; marked improvement in range 3) JG AK47; NND (but it is having problems anyway) 4) CYMA MP-5; NND 5) JG G36k; actually was worse than the stock bucking (the only one of my guns like this - I guess it's just picky) Note: I did not do a "before and after" test. I just installed the Systema and then tested the gun to see if there was any marked improvement. There buckings may have made a positive difference and I just didn't notice because I hadn't shot the gun in awhile, or the difference wasn't so large that it was easily noticeable. Most people will agree that this is the best bucking out there (perhaps with the exception of the Firefly), but don't buy it expecting to see amazing improvement. Different gun types and brands will produce different results."
