  • 100rnd Capacity
  • High density polymer construction
  • Compatible with Specna Arms SA-X series

If you're looking for spare magazines for your SA-X series SMG, you have found them! The 100rnd S-MAG Mid-Cap for SA-X & SA-FX series is constructed from high density polymer with a steel feed spring and is designed to keep up with high rate of fire platforms like the ASTER-equipped SA-X01 and SA-X02.

The magazine can be loaded through the fill/feed port at the top of the magazine body using a speed loader or loading rod and holds 100bbs with no battle rattle whatsoever. The sides of the magazine are textured with small Specna Arms logos to provide extra grip when pulling the mag from a pouch, and the baseplate is enlarged to assist with handling. If you have treated yourself to an SA-X or SA-FX series SMG you need some of these given how quickly these things can empty a mag!

  • 110rnd Capacity
  • Dupont Zytel Polymer construction
  • Bolt lock functional - Peak realism

If you're looking for more capacity on your ASG Scorpion EVO AEG and you hate high-caps, the PTS Syndicate EPM-E9 110rnd Magazine for ASG Scorpion Evo AEGs is what you need! As with other PTS EPM magazines, the E9 is constructed from high-density Dupont Zytel polymer, the best of the best when it comes to polymers used in Airsoft.

The E9 magazine is loaded like any other mid-cap, simply load through the fill/feed port on the top using an Airsoft speed loader or loading rod. Unlike other mid-caps, the E9 magazine provides empty magazine cutoff, also known as "bolt lock", just like the original EVO mags.

The high-vis orange follower allows you to track when the mag is fully loaded through the clear witness window on each side and take a quick glance at the top of the mag with it removed to confirm you still have ammo inside. On each side and the baseplate, we are treated to a dot matrix so you can mark your magazines and keep track of which is which. The front and rear of the E9 mag also include linear texture to improve handling for easier reloads, particularly in wet conditions. If you need more mags for your CZ Scorpion EVO with more capacity than the originals, load up on PTS Syndicate EPM-E9 mags!

  • 200rnd Capacity
  • Steel shell with polymer internals
  • Compatible with SMG-5/SD/K AEG series

If you have dreams of building an old school SMG-5 but you can't find the right high-cap mags, get them here while they last! The CYMA 200rnd Old School Straight High-cap Magazine for SMG-5 AEG Series matches the real steel early style of SMG-5 magazine perfectly, including its straight body design, reinforcement ribs and steel shell construction.

These mags are high-caps for AEGs, meaning extra capacity, less time spent reloading and more opportunities to get kills before refilling. These mags should be compatible with practically any SMG-5 AEG platform out there and also the CM.106, CYMA's AR-9 platform. The mags can be loaded through the fill window at the top of the magazine body by opening the window and pouring BBs in straight from the bottle. With your BBs loaded, all you need to do is to wind the winding wheel on the bottom until it becomes firm, then get shooting!

Whether you are going old school with your SMG-5 build or not, straight mags give this iconic SMG a whole new look and can be a great way to make your SMG-5 platform AEG stand out!

Like other Airsoft mid-caps, the SSR9 Transparent magazine can be loaded through the fill/feed port on the top of the magazine body using a speed loader or loading tool. When filled, this spring-loaded mid-cap won't rattle and give your position away, making it great for skirmishers who prioritise stealth and like to avoid the "tactical maracas" noise of high-cap mags. Keep your SSR9 in the fight for longer with the Novritsch 120rnd Transparent Magazine for SSR9 AEGs!
