Adam Arms has been providing excellent retro-fitted gas piston systems for the AR-15/M-16 rifle in order to convert them into modern day platforms that will continue to be relevant for many more decades to come. It is because of that ingenuity that Madbull is proud to announce the airsoft version of the Adam Arms Gas Block Kit system. Each kit comes with the famous Adam Arms gas block, interchangeable gas tubes, 10 gas tube for mid length system, and 8 one for carbine system. Each gas tube features a built in spring guide. The gas block is built with a R.I.S. rail for attachments and comes with a switch block so the user can adjust the amount of pressure that's routed backwards to cycle the bolt. Obviously this feature is only made to imitate the real product and serves no function for airsoft but it is a unique feature that displays Madbull's attention to detail in making an accurate replica.

  • Fully Licensed Adam Arms Trademarks
  • Adjustable Replica Switch Block
  • Built-in Spring Guide
  • Carbine Length Gas Tube
  • For Airsoft use ONLY, not a real gas block

  • Compatibility: For Tokyo Marui, G&P, Matrix and other compatible M4 Series Airsoft AEG Rifles
    Material: Machined Aluminum

    "Perfect, very well made. Stronger than average metal with a high class finish. Real steel size, pins aren't gonna clear matrix barrel size holes as of Jan 2018, though - you can punch them in as hard as you want but the pins will just begin to mushroom.

    My friend had an old barrel I just traded him for that has larger pin holes that the pins clear, I don't know the brand...straight up 0%...but...if I were to gamble it would be on the 5ku barrel to fit this...the finish looks very similar and mine is some odd carbine length variant with no M203 slot which 5ku offers...what are the odds?

    I bought some matrix gas block pins for $3 to see if they'll fit matrix size barrel holes with this gas block...they seem smaller...will update later if that works...

    5 star gas block either way
