View attachment 555559Apparently I’m confused.. lol
So, do the other Spectre lower solve the slop/wobble issue?
With this much movement, there’s got to be accuracy issues, as the scope will be moving up and down quite a bit.
I put the small o ring on ,that came with my rifle and it didn’t do anything.

Well, that's not our lower so I can't speak to the issue it might have.

With the Lynx 180B it does fit tighter than the original WK180C. Movement really isn't an issue however since the optic is mounted to the upper and fixed to the barrel, it's more just an annoying thing.

We also did a snow test. No failures, just a mess to clean up.

Just thought I would share some photos of our first production super light weight Lynx 180B Upper. It has mil-spec rail, is lighter than other uppers, and has a stiffening bottom plate for extra rigidity.

an actual factual 1913 rail with proper clearance to the top of the receiver?

Hell yes. I'm tired of not being able to use my QD EO Tech.

no locator pin on the back?

Will this upper work for the WS-MCR platform?

Nope. This is pure 180B. It fits snug on the Lynx 180B lower, so no need for a 2nd pin.

No, you will need a Lynx 180B lower.

Here's what the upper looks like on our Lynx 180B Lower

How's your upper working? I had to mod the bottom plate and the side plate to get it to sort of working. Upper and lower lynx is picky with mags and ammo. I have some machining marks that I'm surprised made it through QC on the upper and one of the screw threads for the bottom plate fell out when I removed it. Maybe I've missed it but the lack of posts about the gen 1 upper I've seen make me wonder if everyone had similar issues.

I've JB welded the stripped screw hole like SBI told me to but I'm worried about reliability. Eventually I think it will fail. Mine is in 7.62x39 which might be the reason I have feeding issues. I've asked them a few times if they tested it in that caliber but have never got an answer.

Just before the last big gun announcement from the turd they offered me a refund if I sent it back but I was hesitant because I wasn't sure if the upper would be able to be replaced due to another upcoming OIC. Now that it looks like I have the summer to replace it, they won't answer when I asked if I could exchange it for a gen 2 upper.

SBI knocked it out of the park with the Zhukov adapter and how nice this is to hold but the QC and email answering is lacking.
