    JTK, the id is an open size (14mm dia which is MPR barrel OD) where the pellet travels through, idea - to allow air to expand behind the pellet before it leaves the air-stripper end. Hole at the end of the air-stripper is about 8mm dia.

    Thanks Curt. makes sense.. when I have access to a lathe again I will turn one. was thinking.. me using a carbine in my mpr stock rather than the "weights" on the rail as we discussed last time I am going to turn myself a break from stainless and also take the brass valve cap I made and turn a long on fron stainless. this will add considerable weight to the extreme end of the rifle.

    I was just about to suggest using stainless steel for the brake - will add the weight to the front which is what you are looking for and will looks seriously cool! Just be carefull not to make it too front heavy. With my MPR, the balance ws perfect imo, particularly for standing shots. You might need to counter balance with weight to the rear of your stock. Good luck!
