While we're still oggling for the M4 and MP5 PTW models from Systema, Airsoft Extreme now has the M16A3 PTW with the Burst Fire mode available for us to also serious think about. This costs almost the same as the Systema M4A1 and M4 CQB-R Models. Range should be longer for having a longer barrel... "SYSTEMA had just announced the 2008 mo­del year PTW w­ith vastly improved electronics - LED indicator on the circuit, more reliable FETs, improved trigger response, improved burst function, and will all have type-490 motors standard.

General information:

• Shoots 520fps with a 0.20g BB
• Adjustable hopup
• Weight: 3290g
• Length: 1100mm
• Barrel Length: 509mm
• 12v 2400mah battery available
  
• Magazine capacity 120 rnds (6 Magazine packs are available)
• Single fire and BURST fire mode
• Cylinder sets are available

Sophisticated Engineering — The Systema Professional Training Weapons employ modern, state-of-the-art technologies that are decades ahead of the competition:

• Advanced optical sensors accurately and reliably monitor/control its internal firing routine with extraordinary precision
• Latest “roller-packing” hop chamber design resulting the most consistent grouping and accuracy.
• Revolutionary implementation of the planetary gear box allowing the weapon to operate smoothly and reliably under high internal stress, while reducing the overall package dimension.
• Ultra-compact high-output motor constructed with space-age materials is designed from the ground up to provide unparallel level of performance.  The reduced size also contributes to the weapon’s ability to retain accurate dimension in certain key area.
• Extremely tight manufacturing tolerance ensures superior performance even in the most adverse environments.

Ease of Maintenance — The Systema Professional Training Weapon System provide low cost of ownership by minimizing maintenance needs while reducing learning curve:

• Constructed of top quality materials such as machined / die-cast aluminum and fiber-reinforced polymer, our training weapons are guaranteed with lasting dependability and reliability.
• Field-strippable receiver design closely mimics the real gun’s easy, rapid take down procedure, eliminating the need to learn and remember new disassembling steps.
• Componentized design allows simple and swift access to internal parts, minimizing down-time and repair cost via simply swapping out the component in question.
• Minimum user-maintenance required, with virtually no cleaning needed even after prolonged use.

As Real As It Gets —The Systema Professional Training Weapon System achieves unprecedented level of realism, that its faithful reproduction is the undisputed finest in the industry:

• 100% identical to the real weapon in every dimensional aspect, to a point that the officer will never realize it is a training tool until the trigger is pulled.
• Compatible with virtually all accessories designed for the real weapon, such as optics, rail-interface systems, weapon-mounted flashlights, and even grenade launchers - thus allowing the officer to equip the training weapon in a way that it will look, feel, and function identically to the real rifle used in actual combat situations.
• The first and the only airsoft-based training rifle that simulates the real rifle’s bolt-stop behavior, where the weapon will stop firing after the last round leaves the barrel.  All other airsoft-based training weapons will “dry fire” even after the magazine is emptied."
