  1. I have been following the chatter about the Tokyo Marui H&K MP7A1 GBB since word got out that Marui will be releasing it. Finally, I have one in my hands to review. Big thanks to Echigoya-Guns of Japan for getting me my order in a timely manner. This is my quick write up. The Marui H&K MP7A1 comes with the flip up front and rear sights installed. The box has a separate slot for the 40rd magazine. The box also has a compartment for BBs, and the included 14mm- muzzle adaptor for suppressors or tracer units. A lot of people already know that the dimensions of the gun are similar to the KWA/KSC version of the MP7A1. The front and rear sights are windage and elevation adjustable in both flipped up for SMG use, or flipped down for pistol-sight use. This allows for more precise aiming in either mode. As far as the finish goes, Marui uses its typical ABS plastic polymer finished in matte black with a slight texture to it. The paint used on the selector lever is not bright red (like the KSC/KWA version), instead...its more subdued. The H&K trademarks are present on the grips with the caliber of the RS counterpart engraved on the left side (on the KWA version, the engraving shows 6mm for the caliber). *Do note that the marks around the pin holes are casting marks. The other side has them to. It is not a crack on the material The fire controls are made out of metal. Metal parts include the front and rear sights, the rail system, trigger, select fire lever, bolt catch release lever, magazine catch, retractable stock bars, much of the bolt carrier (part of it is plastic). Everything is well fitted. The joints are well mated and screwed together with phillips screws (none of that .9mm screws that KWA uses). The 40 round magazine is made out of metal for the most part...only the bb follower and feed lips are plastic. Upon inspection, I noticed that the TM MP7A1 GBB has a metal internal casing which houses metal internal parts. This metal casing also reinforces the pin holes that hold the back of the MP7 (The KSC/KWA version does not have any reinforcement around the pin holes which is why they do not hold up as well as they could with powerful gasses at higher temperatures) The hop up can be accessed only if the magazine is taken out. With the MP7's magazine out, you have to push the trigger forward. This pushes the bolt carrier back and reveals the hop up dial. The hop up dial rotates forward and back to adjust the hop. This dial is securely in place and is very very tight. It takes a little bit of coaxing for it to move which is what you want as your adjustments will be more precise and will stay securely in place. At approximately 72 degrees Fahrenheit and the hop turned off, my Xchortech x3200 chronograph was registering .20g BBs around 335 FPS with a +/- 2 FPS deviation over 10 shots at one second intervals using propane. Rate of fire as expected was between 15-16 RPS. For those wanting to get a higher FPS output for the TM MP7, be on the look out for tightbore barrels. Stock barrel bore is 6.08mm with a length of 145.5mm. A tighter bore and longer barrel will definitely increase the power of the Marui MP7A1 significantly in addition to better accuracy, precision, and range. There are a few videos on youtube showing how accurate the TM MP7A1 is. As far as range goes, expect ~200 feet of effective range from this gun. Felt recoil of the TM MP7A1 GBB is definitely more than that of the KWA MP7A1 GBB. The KWA version is more crisp but the TM version has more kick. Other things of note: * The stock can be pulled out and set into three lengths of pull. * The selector lever clicks into place on safe-semi-full auto settings. * The trigger's mechanical safety catches some when pulling the trigger back. A little filing down with a hobby file solves this. This need not be done. IMO, it'll wear down on its own...I just don't want to wait for it to wear down naturally. Doing this mod allows for a much smoother trigger pull. * The plastic feed lip of the magazine holds the bbs securely. The plastic feed lip ensures that the bbs do not get gouged when it gets chambered where as you risk having bbs damaged with metal feed lips. Gouged bbs result in poor accuracy. * The magazine's BB follower has to be held down when loading BBs KSC/KWA magazines have BB followers that lock down into place. * The magazine needs to be filled properly. Having BBs positioned incorrectly may keep the magazine from feeding the BBs properly. Ive tried it on a couple of mags and not having the bottom most BB properly positioned resulted in the bb follower staying down (preventing the bbs from going up). * The back of the TM MP7 where the bolt carrier hits has a spring in place. This spring absorbs the shock from the bolt carrier hitting it. The KWA version uses a rubber pad to buffer the impact. * The nozzle return spring on the TM MP7 is the push type where as the KSC/KWA uses the pull type spring (which are prone to snapping). *The back of the bolt carrier has an o-ring that absorbs the shock from the nozzle returning back to battery. This o-ring however pushes the bolt carrier back which results in a 1mm gap between the front of the bolt carrier and the front of the ejection port. At the moment, I don't have very many photos snapped of the TM MP7A1 GBB Available. When I do, I will post additional ones. Unfortunately, I may not be able to add it into this entry.
