Anyone with a KAC SR-15?

[Lennyo3034]

I have a new to me upper that's having strange ejection. I'm thinking it's the springs in the bolt being worn, so I'm wondering if anyone else down here has an SR-15 and would be willing to let me try their bolt in my rifle.

The SR-15e3 uses a proprietary bolt, so a normal AR-15 bolt won't work.

How many rounds thru it?

Probably around 1500-2000. Ejector spring feels a bit weak, but just a bit. I was hoping to run a different bolt to see if it was bolt related or timing related.

What ammo?

Going by round count, that'd be a touch early to wear a spring out, IMO.

What does "strange ejection" mean?

That's what I was thinking. Worst case, contact Knights. They took great care of me a few years back when my SR-15 was deadlined in a Tiger Swan carbine class.

M855. Rounds are basically dropping at my feet at 1 o'clock. Recoil is very soft so I doubt it's overgassed, so I wanted to test it out with a different set of ejection/extractor springs.
