#BENJAMIN FRANKLIN AIR RIFLE MODEL 317 TOOLS PRO#
These parts are made for pro use and talented hobbeists. 435" barrels to go on barrel end, discovery barrels which need to be spaced forward a few inches and the Benjamin/Sheridan Pump guns. This allows the easy indexing of barrels without unsightly grub screws sticking out. 15MM brakes will need to be heated up to slip onto 15MM barrel stock. All the spacers available are made to be used with the 16MM Brake. The Brake needs to be heated up considerably to expand enough to be fitted to 16MM barrels and then when it cools it is not removable. Various spacers are available so the Brake can be fitted to guns that don't have 15 or 16MM diameter barrels. Designed with a two piece arrangement so the pellet path can align with the brake front end. Mac1 designed and manufactured brake for AirRifles & AirPistols. Heat can allow the removal of the brake at any time. This should only be done to a gun that has had a recent front end freshen up as the Brake will need to be removed if there is any need to service the front end. Wipe off the excess epoxy and make sure there are no problems with the alignment before the glue cures. The Brake glues onto the spacer with the glue being only applied on the spacer OD. It must be clamped down as well as pushed aft to make a seal while curing. It must bottom on the plastic seal or o-ring combination so it seals up and no glue can get into the barrel at the joint. The spacer that glues to the barrel must not bottom on the front plug. Installer will need to dry fit with the plastic seal(s) and/or o-ring to accommodate the various barrel lengths that were made. The spacer glues to the barrel and tube(apply glue to barrel and tube only) for about 2" at the front of the gun so it has plenty of contact area and support. This is for the more handy and is primarily made for Pro use. All Racine Benjamin and all Sheridan rifles will be able to use the Williams peep or open sights still if the front sight is moved back. Front sight will need to be removed or heated and moved aft to clear the brake. Different barrel lengths require plastic seal(s) and or o-ring provided to fit and seal(two plastic spacers and an o-ring are supplied). Mac1 designed and manufactured brake for Benjamin & Sheridan Pump Rifles.
