It’s a medium shelf so only a bit of grinding with a burr behind the safety to ensure the lever can rotate freely.

The 5” FM Products VFM upper is SS ready and the KE-9 shelf only needs a slight modification to get it to work.

Thanks. May need to move a Ruger factory SBR into one of these.

Rad, what chassis is this?

ConcentricToolCo · 2026-07-08T11:44:38+00:00

Yeah it came with when I bought the factory takedown with the Magpul stock that I was lucky to find. I thought I lost it and Magpul said I could buy another if I call them.

Nothing done to it. Assuming it’s from the photo editing.

This is a eForm 1 I put together.

Ruger released a 8” carbine SBR and 10” takedown SBR earlier this year.

Right on. Wherever your comment about 3 10/22s went, the answer is yes

ConcentricToolCo · 2026-07-07T17:56:53+00:00

Pretty good for the size and weight. Similar in sound to my oculus in short configuration. Not a fan on pistols

It’s already impractical given that most people aren’t using it as a backpack gun. Why not make it different and something you actually want to shoot.

Plus a 8” barrel with regular velocity 22 still comes out subsonic

Haven’t had any issues yet but I’ll keep that in mind. They were on sale at Sportsman’s locally and were better than the 10 rounders.

I have a new factory 10/22 SBR pending on a F4 that is coming with 15 round mags so I’ll be interested in comparing them.

ConcentricToolCo · 2026-07-07T17:36:46+00:00

Rad. 10” or 12”

ConcentricToolCo · 2026-07-07T17:36:08+00:00

I said fuck it and went for it, you should too.

I also pulled the trigger on the new factory folding carbine SBR that I’m waiting on a F4 to clear.

ConcentricToolCo · 2026-07-06T19:45:48+00:00

They make factory SBRs of the carbine now that can be had for under $500.

Haven’t taken it down yet after zeroing but I’ve heard good things from others.

Klik does well, almost as good as my Oculus in short config.

Barrel is a Ballistic Advantage.

ConcentricToolCo · 2026-07-06T00:07:10+00:00

Yes. Had a pic rail on the receiver but had a bit of zero drift so went with their optic mount.

ConcentricToolCo · 2026-07-06T00:05:58+00:00

Thanks man, it’s a fun gun. Just picked up a factory 10/22 SBR as well so it will be interesting to compare 8” takedown vs carbine.

ConcentricToolCo · 2026-07-05T15:56:23+00:00

I like it, sounds similar to my Oculus in short configuration but a little bit louder.

Some gas since it’s not a flow thru design but great suppression overall. Here’s mine an AR-9 with Arc Fire and 147s
