No4 Mk1 Rear Sight Question

[woodchopper]

When you remove the rear sight axle to change out the rear sight, that plunger will jump right up at you from it's hole in the receiver rear bridge, directly under the rear sight.

vicious wee beastie that plunger is..

and after it attacks you it will immediately scurry off to hide under some furniture and then you have to look for it. Sometimes it will get panicky and shed its spring along the way, giving you double the fun of finding small parts.

If you are going to shoot it, Mk111 is the one. Plunger and spring aren't
that easy to locate anymore.
