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.

5 SYSTEMA High Performance Hop-Up Packing / Bucking for Airsoft AEGs *****
Systema Bucking

"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.

"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

"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."

Best in Class Customer Service

Same Day Will Call Pickup

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
