I have a danish return garand with a lock bar sight that I would like to replace with the later sight. I need directions on how to remove the lock bar sight. Any help would be greatly appreciated. Thanks, ken

Hi Ken,

I can go through it bu the easiest thing to do is to go to the CMP web site. The home page has a tab called "Garand Tech. Info." This gives you detailed step by step procedures for detail stripping of all the Garand componenets including the sights.

Note that the lockbar sights were staked in place on the end so you have to be careful when you remove the lockbar not to strip it out.

When a lockbar sight is removed, the stake is also removed when the lock is screwed off, is this correct? If so, a rifle, to have anything other than a staked sight would mean it was off the rifle, either a replacement, or worked on for some other reason? Thanks,

When the rifles left the arsenal or were repaired by unit armoreres the lock bar was staked in. If the stake is removed it does mean the lock bar has been off the sight. However, one reson they went to the T105E1 type sight (which was actully approved for use during the war) was that the lockbar is small and GI's could screw them off the pinion and lose them or they could be lost when removed to clean the pinion of sand, dirt etc.

So the staking could have been removed when the weapon was used or to replace the sight or lock bar or to replace the sight pinion or other sight parts. If a rifle is an aresenal rebuild done from about 1947 on, it would likely have had the sights replaced with the T105E1 type.

Actually the long pinion replaced the short pinion for this reason. The short pinion, used from the earliest production until sometime around late 1942, had a flat end and either utilized a flush nut or type I lock bar. The long pinion was introduced sometime near the end of 1942 and was bigger around so that the lock bar end could be hollowed out at the end and the edges flared out (staked) so that the lock bar couldn't or wouldn't fall off as was the case with the short pinion. I do know that during the war the T105E1 rear sight was developed but I am not aware of any ever being installed on WWII rifles that were actually used by troops. In other words, this later sight would be considered post war and would be correct for those in the 4 million and above serial number ranges. The last rear sight used during WWII was the lock bar, with long pinion and type III or squared-ends lock bar.

As a side note, there are several different versions of the lockbar and some type II lock bars aren't as rounded on the ends as some others. To identify a type II from a type III, look on the back side and if the cutouts are curved, it is a type II. If they are straight, it is a type III. Flush nuts and type I lock bars were used on the smaller diameter short pinion, and therefore the holes are a smaller diameter.

Do you guys think this lockbar is legit, or a repro? Thanks for looking! The rest of the sight is: later sight base, SA elevation pinion, WRA windage knob, and later cover.
