Manual

When using the cleaning jag,keep in mind that patch size and thickness are
important. Start with a patch that is approximately 2 1/2" square (or in diame-
ter). Position it over the jag as pictured in the illustration and try it in the bore
of the firearm (wet patches will enter more easily than dry ones). If it seems to
be too tight - don’t force it. If your trial patch proves to be too tight, use a small-
er size patch and/or thinner material.
A patch which is too small or thin will pull free from the jag teeth during
the cleaning process. Such “lost patches” can be quickly retrieved by use of the
worm (see illustration). Cleaning will go easier, however, if you establish and
maintain an optimum patch/jag/bore fit.
Thompson/Center does not package the worm with each firearm. This is an
optional tool and must be purchased separately (one size fits all calibers - see
current catalog). The worm is an extremely important muzzleloading tool and
every shooter should carry one in his implement bag. While its prime purpose is
to retrieve “lost patches”, it can also be used for field cleaning. To do so you sim-
ply catch the cleaning patch on the tines of the worm and push it into the bore
in the conventional manner.
Iron Sight Adjustment
For The System 1
™
The System 1™ is equipped with the a standard rifle rear sight as shown
below which is adjustable for elevation by sliding the elevation blade up to
raise the point of impact and down to lower the shot’s impact. It is necessary
to loosen the elevation lock screw (by turning it counterclockwise, as viewed
from the rear) before sliding the sight blade to the desired setting. To adjust
the windage it is necessary to move the entire rear sight leaf left or right by us-
ing the slotted scr
