I was going through my bags of small parts to get them organized an come across a bunch of parts that were in a repair kit I got from Bushmaster quite a few years ago. I identified all of the parts except these.


I know the flat piece is part of the rear sight assembly and am wondering if the springs are sight parts too. I know the larger spring is not for the buffer retainer since it's too large. Here is a picture of the springs with a sight diagram from the USMC TM book. I'm thinking the two small springs are for part # 4 & 13, but have no clue about the other two springs.

Hard to tell what they are unless you have a ruler or something in the photo so we can see how big they are. The black piece looks like the insert from the front of a Magpul AFG, but the springs are hard to tell without knowing their exact size.

the big spring is 1" long and slightly larger diameter than a buffer retainer spring. After looking on WOA's site I think it's a rear sight elevation spring.

medium sized spring is 3/4" long and about same diameter(it is a touch bigger) as the safety spring. The way the spring is stretched out is throwing me off, it doesn't match anything I've looked at.

Two small springs I'm now pretty sure are rear sight index springs

The flat piece is the rear sight flat spring.

The medium spring is the front sight detent spring. Looks like you've got a full A2 sight spring set.



 

Thanks. Do you know if the springs for the rear A2 sight will work on the rear carry handle sights also? I would assume the springs would be the same.
