Abstract: A conduit (5) with a bullet passage (13, 17) extends forward from a gun muzzle (7). Inner and outer concentric chambers (25, 29) surround the conduit and a forward portion of the barrel (3). A gas path (P2, P3, P4) is provided through sides of the conduit into the inner chamber, thence to the outer chamber, and then exits to the atmosphere at the front of the outer chamber. Each chamber has longitudinal lines of sight between front and back sound reflectors (R1-R2, R3-R4), and no longitudinal line of sight from the back reflector (R2, R4) to the atmosphere. The gas path through the suppressor is at least 6 times less flow-restrictive than the gas path through the bullet exit (17) or back into the barrel bore (4), minimizing backpressure. The gas path (P3) between the inner and outer chambers is through apertures (33) limited to a lengthwise middle portion of an inner shell (21) that divides the chambers (25, 29).

Abstract: The present invention provides an apparatus and associated method for protecting an object from the effects of inclement weather. In one aspect, the present invention provides an apparatus comprising a cover which has a central portion and a skirt portion. The central portion further comprises a plurality of pad members which are disposed about the central portion to allow an efficient and convenient method for folding the apparatus. The skirt portion further comprises webbing and eyelets which are used to secure the apparatus to an object in the presence of inclement weather.
