whats up gents i bought this alias from a friend like 6ish years ago, never had a timmy before this one so i thought the bolt was normal (ive shot a few others now), then i saw some new timmy bolts and saw they dont have any holes in them, just wondering what this type of mod would be called, ive known its not stock for awhile now i just never cared about putting up a thread about it. any help identifying would be much appreciated. it seems like im able to run the lpr down to like 50 without any negative effects, could this be the reason why, also my alias is by far the smoothest timmy ive ever shot. i chronod it last weekend n it was shooting like +/- 2 over the chrono, just very consistent.
yes i know the bolt is old as ****
