Just got out today to shoot the SWR Spectre on my 10/22 target for the first time. Wow. Really quiet. Only hear the action and the bullet hitting the backstop. Very impressed and happy with the purchase. Cant wait for the barrel for my Buckmark to show up.
There is both an AR being shot a few lanes down and a hammer falling on empty chamber in the video to give a representation of the actual sound level.
