It is a vastly superior way to mount a muzzle can to a rifle barrel.The resulting joint is many times stronger than any single-point mount could ever be.Because of the geometry of a two-point mount, a small error in alignment will not progress into a much larger error at the suppressor's muzzle.

Many of us have seen movies in which a fitted case full of components (stock, action, barrel, forearm, scope, mount and silencer) was assembled in the field, and then used to complete an important assassination. No enforcement officer in his right mind would ever assemble a rifle on the spot on a callout at a crime scene and expect the weapon to hold its zero.

It might, but such an occurrence would be an abnormality.

We are talking about no discernable, cold shot shift after a day, week or year, at 180 m or 200 yards.

Bullet contact with any one baffle in a suppressor usually results in tumbling, with severe consequences for those baffles that remain downrange of the event.

That same torque tends to cause a suppressor to loosen if the suppressor is held in place with right hand threads, which seem to be the norm. This zero remains even after the suppressor has been removed for cleaning and replaced.

One must be constantly vigilant to make sure that a rifle's suppressor remains tightly screwed in place. All Russian and German flash hiders (and some suppressors) are attached with left hand threads. As long as the replacement torque is about the same, the zero will be unaffected.

We feel that this configuration (with the barrel in compression) is not as conducive to accuracy, although it may ease manufacture of the suppressor.

However, to our great surprise, we have seen suppressed .308 systems (with compressed barrels) that appeared to be fairly accurate.

In this case, the strength and stability factor is much improved.

Unfortunately, many suppressed rifles with single-point mounts suffer from a wandering zero. The two-point mount usually attaches a barrel to its suppressor with threads at the muzzle, and with a collet, O-ring, or conical joint about 20 to 25 cm or 8 or 10 inches behind the muzzle.

Using a rifle which is only occasionally silenced is an invitation to either a lawsuit or to poor field shooting, as any rifle will carry a different zero without a suppressor, as opposed to its zero with one.
