Description

CNC aluminium HopUp chamber for M249 machine guns is made of a single piece of aluminum alloy 6061- T6 with red anodized finish . It is a material with high strength , and  is lightweight. Weight of the chamber and only 18,9 grams. It is not  re -brand or a repackaged product of another manufacturer . The chamber was made in the Czech Republic .

Chamber is compatible with the M249 series  by manufactures: A&K, PJ, Classic Army, Echo1, Matrix.  Optimal nozzle lenght is 21 - 21,5mm.

Basic characteristics:

  • Made on high precision CNC machines. (chamber, adjusting ring, center ring)
  • Better sealing. (You may test more different HopUp buckings to reach the best performance)
  • Durable body with red anodized coating.
  • Compatible with the stock plastic nozzle.
  • Packing include 21.5mm CNC aluminium sealing nozzle. Thanks to modified construction it fit on stock A&K cylinder head. ( Because A&K cylinder head is little bit wider. Diameter is somewhere between standard and NBU.)
  • Nozzle from the packing also fit on standard (not NBU) cylinder heads.
  • Chamber is fully compatible with the stock plastic nozzle. So nozzle replace is on customer decision and not condition for good chamber function. However, nozzle replacement may cause slightly better sealing and increase performance.
  • Suitable for nozzles 21 - 21.5mm (tested on A&K M249)

Each packing include:

  • Brass center ring.
  • POM pressing roller.
  • Spare o-ring under adjusting ring.
  • Aluminium nozzle.
  • Durable HopUp bucking (AimTop)


Assembly notification:

  • Try more different buckings or nozzles (if you have) to test and reach the best sealing.
  • Apply silicone oil or grease on the cylinder head nose, before you insert nozzle
  • Insert nozzle carefully to avoid sealing o-rinng damage. Try to get nozle nose in to middle of the o-ring. Sliding of the nozzle is smooth after that.
  • Apply silicone oil or grease on the HopUp chamber body before black adjustable ring insert.
