Guarder Replacement Aluminum Magazine Shell for Tokyo Marui Hi-Capa 5.1 / 2011 Magazines (Color: Black)

"It does not have blowback, but the TM pistol here (http://www.airsoftpost.com/product_info.php?cPath=21_493&am-
p;products_id=26970) does. However gas blow back guns (GBB) would work better if your looking for blow back.

"The Marui version of this is $150 and it probably won't last 12,000 rounds. If you want a heavy duty piston, get gas guns. For an AEP, this is still probably the best AEP to buy since it is identical to the Marui one for 1/3 the price...

"It is a good gun and the full auto is a great feature. However it does seem to jam alot i dont know if it is the gun or the people i play with but it has jammed 3 times so far( The people I play with somehow pyulled my MP5 silencer hard enough to loosen the screw holding the flash hider to the rest of the gun i have no idea how...)

"I have two of these. I have never been impressed with AEPs; their FPS is just too low for my taste. But otherwise this is a pretty good AEP; built ok and relatively accurate. The mag, slide and other external metal parts are like a softer alloy rather than aluminum or steel. I�m familiar with this alloy; if you try to bend it or if it gets bent and you try straightening it, it is more likely to break rather than bend. I�m waiting for AEPs to get better in quality and have an FPS up in the 320 to 350 range with .20g bbs. 4 stars for a good low cost AEP.

"looks good, feels good and shoots good, but it isn't very strong (obviously because it is electric) S'allright

"Does this gun have blowback??? Because Im looking for a gun that has blowback.

"It shoots as expected for an AEP. However, be aware that it breaks easy. It slipped from my holster on to the ground (only a few feet) and the silencer broke off. The connection from the battery broke as well, and it wouldn't shoot anymore.

If you are careful, it is a decent gun - though I would recommend saving the money for a more durable GBB.

"I'm adding this as an update to my previous review on this DE M84A M9. I have two of these; and one I've had for two months. This would be the one I have used the most. I have only used this one for target shooting in my back yard and in my basement using the shooting range I have set up. All my guns stay in padded hard cases; none of them have ever been dropped or banged against anything.
I have run about 12,000 rounds through this M9 and it has begun to fall apart. First it was the mock hammer; it broke off (it has only ever been touched once when I got the gun checking it out). Next I started seeing fractures on the slide (waiting for it to break). The selector and safety switches are becoming very loose. It appears that the metal parts are even a poorer cast metal than I had originally thought. Apparently, just from sitting there plinking, the vibration of the gun firing is destroying it. I now give it 2 stars, they made an effort but they need to make it from nice aluminum or steel.
