The Lonex 70 Degree Bucking is an easy way to increase the performance of your airsoft gun. The Bucking is what the BB contacts before leaving the barrel. As the BB gets pushed inside the bucking, the air nozzle will seal against the bucking lip to ensure that the air being compressed from the cylinder travels completely through the barrel leading to maximum velocity output. A damaged bucking would lose air compression leading to a lower velocity output. Keep you airsoft gun performing like new with the Lonex Bucking. This bucking is designed for airsoft guns with a velocity output above 360 feet per second.

Product Information:
Lonex makes quality components from magazines to buckings like this. This is really a great bucking especially for the price you pay. Having a rating of 70d, it is quite durable, and suitable for 400fps guns. Includes the bucking, barrel ring, and regular hop up nub. I bought two of these as well as a G&G Green just because they are that cheap. Depending on your gun/hop up specs you may need to trim the bucking a little shorter to prevent jams.

70d -- durable and good for 400fps guns
Includes nub and barrel ring
Performs well

Nub is not entirely smooth, kind of seems like it's scratched
Harder to turn inside out for modification than lower degree buckings

Product Information:
My go to bucking for almost all my builds.
I just love this bucking, its cheap, high quality, sturdy. It has pretty good performance by itself, but I usually flat hop it and it works perfectly.

It works great in my 500fps R-hoped DMR in a lonex hop chamber, in my flat hopped P* jack Krytac (Krytac hop up) and in my girlfriends flat hopped G&P

High quality material
Comes with a barrel ring

Thick material, so might require a lot of silicone to install in some chambers
