Ultimatum HMB action, who ordered one?

[rugbydave]

The no recoil lug thing really mystifies me. Going with a proprietary tenon spec/coned breach isn't a huge deal as Ultimatum = IBI so they can offer their own prefits and honestly, coned breaches feed quite well but not having a keyed or pinned lug is just bizarre. I get the cost savings of not having an integral lug (you start off with a smaller chunk of billet and there's less metal to machine) but the added cost of having a "key" for the lug (like ARC does for the Nucleus) or even just pinning a lug (like you'd have a smith do for a R700) has to be very minimal but totally avoids the annoyance of having to buy/build a fixture to align the lug whenever you want to swap a barrel. Just a really strange design choice, imo.

That extra effort qualifies you for one of the benefits of a prefit: not having to send in the action to obtain a new barrel.

However, it doesn't qualify you for the other benefits:
- lower price options (i.e. PVA from GoBig)
- freedom to try a different gunsmith
- freedom to try other barrel brands

That's true.

If you branch out and want different options, it gets much more annoying.

That's just the brand identity of Ultimatum.

They've always made very bizarre and unusual design choices, I guess to separate themselves from the rest of the herd.

I think they are adding a pin for the lug. I saw something about that on their fb page.

Looks like these are shipping now and they have included a pinned recoil lug! Excited to finally see mine.

I got my 223 bf tactical action in the mail the other day. Pretty smooth, nice fluting, nitrided outside and dlc coated inside. Should make for a nice build.

Any updates on the accuracy of these actions?

That’s more of a Barrel question


But I do have one and i am waiting to have a 30 “ barrel chambered up on it in 7 PRC

The action is very nicely machined and is very smooth ! I suspect it might be ACCURATE

I run a IBI Precision Systems HMB with their Carbon Tactical barrel. Only have 60 rounds through it so far but it shoots and the action is smooth and nicely machined/coated.

Bought one of their blems last year, didn't have a build plan but it was hard to pass up a deal on a LH action.

Recently found someone selling a new 26" HMB prefit in 6 creed on here and spun that on. Triggertech just had a sale, added a TT Special. Living in a XRS chassis that I had here, likely switch it up when Black Friday comes around.

Took it to the range Thursday night to sight it in. Loaded 15 rounds, mild load of H4831sc under 107 SMKs at 2.800". Forgot my shooting bags so just shot off my bipod. Sighted it in and then shot the remaining 9 rounds into a 100 yard group. Very happy so far!
