- Full metal construction
- Gate ASTER SE MOSFET/ETU
- Warhead 36K Brushless Motor
If you've always fancied a WWII era platform but the lack of pre-upgraded options put you off, the Bolster Tuned StG-44 Sturmgewehr AEG is here to save the day! Translating Bolster Tuned performance into a hefty and authentic full metal Sturmgewehr replica, this utterly unique upgraded AEG was put together by the same team that built the ultra-high-end Bolster Armouries ONYX AEG series and benefits from all the experience and expertise gained from a lifetime of Airsoft tech work and plenty of successful Bolster Tuned AEG drops.
Inside, the Tuned StG-44 is rocking a Warhead 36K CNC Black Brushless Motor, Bolster Armouries EZO bearings, and a Bolster Armouries Stainless Steel Sector Gear Screws along with complimentary parts to keep it running reliably long term. To provide the advanced functionality everyone expects from a Bolster Tuned build, the space-aged Gate ASTER™ SE MOSFET/ETU is installed, offering a wealth of programming options and equipped with the latest EXPERT Firmware.
The stock gearbox shell was found to be woefully inadequate for Bolster Tuned performance parameters; as such, the team based the internals around the CYMA Platinum Complete V2 Gearbox, upgrading the usual parts and only keeping the best bits. Inside, the stock piston head was swapped out for the Gate EON Power Hybrid Piston Head, the tappet plate was upgraded with the FPS Softair Carbon Fibre Reinforced Tappet Plate
To ensure you get the accuracy and range Bolster Tuned platforms are renowned for, the team switched out the stock gear HOP-up unit with the Novritsch Polymer Rotary HOP-up unit and added the 4UANTUM Friction Pro High Performance AEG HOP-up Bucking to seal the deal. The stock 6.08mm inner barrel has also been swapped out for a KRYTAC 6.05mm Tightbore Inner Barrel, chosen for its high-quality internal finish and wide HOP-up window, ideally suited to the 4UANTUM bucking.
- Dual Tone Frame
- Gas Powered Recoil
- 24rnd Gas Magazine
A gas powered semi-automatic M9 replica, which will cycle the slide with each shot for a realistic recoil action, and is made with a Polymer slide to ensure a snappy response from the Trigger.
- Non-Blowback Replica
- Co2 Powered
- Target Gun
A 1911 Co2 None Blowback replica by Cybergun, excellent for target practice at home or on a range. No reciprocating slide means more gas efficiency down range. However this does boost the FPS above most site limits, making it unsuitable for skirmish use.
- Full metal construction
- 6.03mm Tightbore inner barrel
- Optics ready slide - 20mm Weaver compatible
If you're looking for a cheap and cheerful sidearm with more than its fair share of features, the Double Bell 304 Burgundy Viper Hi-Capa GBB Pistol should be right up your street! This full-metal Hi-Capa platform is based on a high-end real steel pistol we all recognise, rocking an optics-ready slide, front and rear slide serrations and a pre-installed compensator to complete the elite look.
Despite its very affordable price point, the Burgundy Viper is supplied in a wave foam equipped hard pistol case with a spare nozzle and a 20mm Weaver optics mounting plate included, giving you some elite features for one of the most affordable full metal Hi-Capa platforms on the market currently. If you're searching for high-end looks for an entry-level price, the Double Bell 304 Burgundy Viper Hi-Capa GBB Pistol is exactly that!

- 500 FPS on 0.2g BBs - Hits hard!
If you have your sights set on a sniper rifle but want something with a more militant look, the CM.702B M24 from CYMA is exactly what you need. This spring bolt action sniper rifle is based on the real steel M24 SWS, the US Army's standard sniper rifle and comes equipped with a 6.03mm tightbore inner barrel straight out of the box!
As far as affordable sniper rifles go, this is one of the most consistent we have seen, hovering around the 500 FPS mark on 0.2g BBs with only a couple of FPS deviation between shots. While it isn't based on the VSR-10 system, it is compatible with upgrade parts for the Classic Army CA/M24 but for all but the most particular snipers, upgrades shouldn't be necessary. Just slap a scope on top and get busy from your hide in the woods!
- Full metal construction
- Stylish spiral fluted outer barrel
- Ultra-light side with exceptional speed
For those Hi-Capa fans who feel the need for speed, the Hi-Capa 5.1 High Speed Custom from Golden Eagle takes out of the box Hi-Capa performance to even greater peaks. The slide of this Hi-Capa has been reduced to practically nothing at all, giving it an incredibly fast cyclic rate with reduced recoil, resulting in a vast improvement in gas efficiency and shot to shot consistency. If you are the type of player who is all about performance, this Hi-Capa would be perfect for your needs, and would almost certainly excel with an HPA rig connected as it does with a standard green gas magazine. The skeletonised slide design and spiral fluted outer barrel would also appeal to those out there who appreciate the minimalist race-gun aesthetic.
- Full metal construction
- Lycoris Recoil style replica
- Menacing strike face compensator
If you're a fan of the Lycoris Recoil Anime TV series or appreciate sharp things, the AM.45 "Chisato" Detonics .45 GBB Pistol from Double Bell is what you need!

The AM.45 Chisato boasts full metal construction with a seriously sharp strike face compensator which Double Bell wisely chose to make from high-density polymer so no one gets hurt! The internals are all Tokyo Marui spec, meaning if you want more accuracy and range you can upgrade the HOP-up rubber and inner barrel easily, with other options available for the more technically proficient.
Whether you love a compact GBB pistol with a unique look or are a fan of Lycoris Recoil, the Double Bell AM.45 "Chisato" Detonics .45 GBB Pistol is a fantastic, affordable way to expand your collection!

If you are a lover of classic assault rifles, you will have noticed the absence of this Swiss beauty in AEG form, especially in full metal AEG form.

Take the JG S-551 to a Airsoft site and you will turn heads, then when you start shooting you will turn tails!

If you like the iconic Dragunov SVD but you don't want a rifle a mile long, the SVD-S should suit your preferences! The CM.057S Dragunov SVD-S is constructed entirely from metal with a large proportion of steel parts and is a perfect replica of the SVD variant issued to Russian paratroopers and mechanised infantrymen, the SVD-S.

This is a Dragunov for the Airsoft marksman on the move!
This AEG is based on the Real Sword SVD design which means it is already locked to semi auto and uses a custom gearbox design with an advanced gear adjustable TDC HOP-up unit. This superb internal design pairs perfectly with the super long 590mm inner barrel to make the SVD-S a great base platform for a DMR build.
