    "Very fun and huge supressor to show off- not practical at all; but nobody buys it for that.

    "great quality, good finish, high quality strong design and super strong threads. perfect for my Cybergun F.A.M.A.S. DMR with the silencer adapter, great for hiding my 590mm inner barrel. comes with the caps, two threaded, (which you can put one on the front and one on the back of you don't want the rounded front one on there), one +14mm and one -14mm plus the rounded front end cap. super long, don't let 335MM confuse you, it is like 14 inches long, but perfect for my set up. 5/5 would recommend

    "This is an absolutely massive barrel extension!! It is the largest I have been able to get my hands on.


    PROS:
    - lightweight aluminum
    - sturdy, no wobble
    - professional finish


    NO CONS!!
    All around an impressive barrel extension for those with that nasty inner barrel protruding from their guns!
