Sumo Sight Australia has teamed up with Davies Triggers Australia to produce a high quality barrel tuner to suit Sumo Fixed height front sights.

The Davies tuning system incorporates a threaded sleeve which is attached to your barrel by Loctite thread locker # 243. The sleeve alleviates the need for the barrel to be removed and threaded as is the case with some tuners. This system also insures there is no contact by screws to the barrel which can cause damage to your muzzle if over tightened.

The Tuner itself simply screws over the top and has fine adjustment and marked increments of 0.003", after you find the tuning point, it is locked firm in place via the grubscrew.

WEIGHT: 91 grams
Suits barrel spigot diameter: 0.75"
