    Type 3 lockbar sight question

    Hi all I have a question that I'm sure has been asked before but I'm wondering who uses this sight and if it's worth changing it out. my rifle has the post war style which it seems like most have from what ive been reading online I like that lockbar are the correct sight and matches my barrel and receiver. I have been reading that they don't stay so tight and loosen up so looking for some advice thanks in advance

    I have NEVER, in 30-plus years, had a lock bar sight come loose. I have, however, had the new type come loose. My match rifles all have lock bar sights for this reason.
    The lock bar sight that was prone to loosening, and sometimes falling off is the type I short pinion. The flush nut sights had a loosening problem as well. The length of the pinion was increased, diameter reduced, and a finer-pitch thread was used in the type II and III sights--problem solved. Also, just so you know, type II and III lock bars are NOT distinguished by round or square ends. It is by the machining, or lack thereof, on the under side of the lock bar. There are, indeed, type II bars with square ends and type III's with round ends.

      Thanks for your help the place that had them was dupage trading. I think 2 they sell the entire sight with the base but said I can remove and install it into my base I guess I could see what one is better thanks again

        Never had a problem with either type loosening on their own. The later T105 type IMO is easier to adjust for shooting

          Hi all I just installed the lockbar sights I ordered from dupage trading . Like you guys said they do seem to tighten up very well . The only thing is the color of the knobs are darker than the sight base on my rifle it's more black then the greenish color . Just wanted to know if any of yours are this way .I'm sure you never will match parts when you add them just curious thanks Stephen

            Sight base that came with sights may not be original to sight knobs and sight cover. Its also not unusual for colors on original rifles to not match, they will vary

              They won't match because of differences in the parking solution at the time, when they were park'ed and the base of the parent material. All matching just screams "REPARK" any way, which may, or may not be what you want.. There were millions of them made and if they weren't all done at the same time in the same batch, they ain't gonna' match.

                    Here is a photo of a Type 1 lock bar, all you have to do is remove the flush nut (spanner nut) and replace with the lock bar. These are quite expensive and often faked by installing a sleeve into a Type 2 lock bar. Old photo from 2006 showing the Type 1 on a early rebuild, barrel is S-A 10-41
