Gunworks Overbarrel Suppressor (unfitted - standalone)

Introduction

.223 and up to .30 cal suppressors now available for purchase as a standalone unit, can be threaded by your own gunsmith or by yourself if you have the equipment. 
Thread ½ UNF available directly off our shelf, other thread types are available but allow 5-7 working days for the suppressor to be built to your thread type. 
Threading directions available with ½ UNF threads. 
Maintenance instructions is provided with all overbarrel suppressors.

These suppressors are a 2 point mount and are impossible to knock out of alignment (as may happen with muzzle forward cans). All suppressors incorporate a barrel isolator tube which prevents carbon and gas sticking to the outside of the barrel under the suppressor.

Sound signature of a high velocity round for any calibre, ie .222 Rem to 7mm mag, is similar to a stock whip cracking (or a 22 magnum thereabouts), that is the noise of the projectile breaking the speed of sound. When used on game, the animal only notices the "stock whip" like crack originating above them. The position of the firer is undeterminable. This often leaves the animals milling and unsure of where to run, particularly at night under a spotlight.

Maintenance:
Maintenance instructions is provided with all overbarrel suppressors.  In summary the key points of the suppressor maintenance is:
1. Try to avoid leaving the suppressor on your rifle while in storage as moisture is a by product of powder combustion and may cause the muzzle of the rifle to rust or corrode.
2. Don’t clean or dismantle your suppressor, carbon build up is good as it helps to quieten down your suppressor even more.
