Lambda "Five" Precision Stainless Steel 6.05mm Tight Bore Inner Barrel for Tokyo Marui Spec AEGs (Length: 141mm / MP5 PDW)

"Very accurate barrel. Use it in one of my TM P90s. Shots are floaty I find but very accurate.

"I upgraded the barrel in my Scorpion EVO with one of these, and along with a Modify Ryusoku hop up bucking, the gun shoots absolute laser beams. I'm easily outranging local players with Krytacs and other high end guns. Every time I let someone else shoot it they just have a look of incredulity on their face and can't believe it has that sort of range and accuracy. So basically, yes this barrel is amazing. I liked it so much I'm buying a couple more for other AEGs, because the quality to price ratio is the best on the market, IMO.

"I got the 455mm length for my ak, and this thing shoots laserbeams! Great product.

"It's ok. It has very sharp edges and will chew your bucking to bits. Apparently a common issue.
