  1. Reducer 5 Star Review

    Posted by on 3rd Apr 2021

    It does exactly what it is supposed to do -- reduces your stem size - I use it so I can get a SG14 single shot cone to fit my SG18 stem - it sits flush with the stem so it doesn't make the cone stick out - it's awesome.

  2. 18mm-14mm reducer 5 Star Review

    Smooth finish, nice low profile, doesn't extend the length of the stem more 7-8mm. Works nicely.

  4. HANDY INDEED 4 Star Review

    These are a highly valuable addition to get more configurations out of your rigs, does what it says, no fuss. (I only rated 4stars due to a slight crooked cut to the small end of the joint, which does not affect its function in any way, just a minor cosmetic fault) Beefys has provided 5 star service EVERY time i have ordered from them.

  5. Essential for SG18 Billys 4 Star Review

    Posted by on 6th May 2016

    If you have a SG18 billy this little adapter is a must. The combinations of ash catchers, cones and billy are endless now that you can use SG14 pieces together with your SG18 rig.
