Is there a finishing “cap” for the size of carbon fiber tube you found? Something to cover the front end of the tubing. What’s your plan there?

What do you mean? I wasn't planning on putting anything over the end of the tube, just use it as is for a basic handguard, in the same style as the kaw valley and wiland pcc handguards, just with a big enough diameter to accommodate the gas tube to keep mine a semi auto.

Does anyone have a direct comparison as to how much more one would weigh with a regular aluminum lower and parts kit including Larue MBT2S compared to one with a TN arms carbon fiber lower and a New Frontier poly LPK?

I'm looking at the Solo 300 upper, Shaw port-less barrel and a KAW PCC handguard with a KAK buffer tube and Farrow tech "stock"

I have a spare PA 3x micro-prism in an ADM mount, so I'm hoping it would still be under 5 lbs.

There's a database of a lot of ar-15 parts with weights so you can get a close estimate of any parts combo you want, it's located here but you gotta have a gmail account so you can view the spreadsheet.

Guy is selling a riverman gun in the classifieds.

Bolt action AR.

Took the pictures from the ad maybe there’s something useful here.

Looks like the shop closed up to reopen next year.

I am seeing mbr10 on the side…. Maybe an ar-10? It definitely looks like it needs to go on a diet.

Let us know what you find for a clamp.

Speedway motors has gucci tubing clamps or Clark Customs sells their clamp. Just depends on the tubing size. I've used them both and they hold up great to field use.

Good to know, I was thinking of going low tech, lightweight and just sectioning off another part of the leftover tube and building up two flanges with some epoxy and CF to run a bolt through to a nut on the other side, but I'll experiment first and post when I have results. The Clark custom is what I took the idea from when I found that barrel nut

TN Arms takes a while to fill orders... like 3 weeks...even when they show in stock. And I would only buy a stripped lower from them, the complete comes with heavy mil spec parts. The NFA lowers are only a smidgen heavier and same price I believe. I do like the brass insert in the TN Arms carbon though.

I ordered two stripped lowers from them 3.5 weeks ago. Emailed a couple times for an ETA and got no response. Called 3x and nobody ever picks up. I sent another email asking for a refund, but I doubt they'll answer; probably just issue a chargeback and move on. Their website isn't even working today.
