With some talk about Ruger factory muzzle brakes I decided to take a look of what I had. In all I found 18 brakes some in boxes and this don't count how many may be on guns that if I remember may be about 4 to 6 guns. Two were with the "INC" and I noticed two types of font in the non "INC" brakes. Yes some the roll marks were backwards from the others. Guess you can say as a collector there are a few variations. Here are some pics. Notice on the non "inc" how the first line "RUGER" lines up with the second line "CONN". I also think the letting may be a bit smaller on one than the other.
