for what its worth.  this is not a new concept.  Robinson I think is probably overreaching quite a bit.  FAL's have had that style of bolt release since Alex Robinson was a twinkle in his daddy's eye.

His patent isn't for the bolt catch, it's for the weapons system that employees said style of bolt catch.  Rather, all of the features of the XCR combined.  And the XCR is far from the only weapon today using a plunger style catch.

I like it.

Maybe consider a PDQ style"hockey stick" style control too.  I don't think PDQ is ever going to make more, they have been out of stock for years.

Whoever is making these lowers, will it be made in house or sent out to a machine shop?

Sent out to machine shop.

At one point in my firearms adventure we had in house:

Two Makino A51NXs on a 12 pallet automated cell
Two Nakamura WT-150 Bar fed Turn Mills
A Makino PS-95 with a celled loading robot
A standalone Makino A61
A Haas VF-2SS with a pallet changer
And a cute little TL-2 (That I tried to purchase back a few months ago)


The overhead on that is.... A lot. That often can translate into pricing increases to the customer depending on where the shop is financially.


I am taking a different approach this time with Inoculum-Group.  


At least as a start.

Just my quick two cents. I also prefer the more traditional looking ambi-bolt release. Thanks for including the community in this design, it is awesome to see it come to fruition!

I have a M60 pintle mount going onto my Hilux later today with a KNS picatinny adapter to help further this discussion point

Will get pics once the L6 arrives (inbound, delayed thanks to the UPS thief)

Those dont look very durable for leaving mounted while driving around. I think they may be made more for mounting the gun and shooting after parking.

It’s 100% marketed towards the SXS coyote / hog hunters so I’m sure it’s not the most rugged.

My issue is trying to get someone to make a pintle mount made for various size tubing to be mounted to SXS or four wheeler.

Don’t want to drop $1k on the mounting interface for a $3k rifle.

What size do you want it made for?

Its not too difficult to buy some steel roll bar clamps from summit, and make up a mount with a pintle socket from ironcreations. Hardest part of that is making/locating the locking pin/bolt.

I rolled the design I did over to Dan so he can make it actually correct.  

Will update with what he comes back with, and do a couple more rounds of thoughts from the group, and also get some quotes out.

Please make sure that the lower is compatible with tribe tactical supply nutsacks. The locking tabs are wider than the USGI nutsacks, and I believe they won’t work in the Black Widow lowers for the MCR.

Other than that, and possibly trying to center the nutsack without impacting feed angle, I think the design is hitting all the high points. Ready to throw down cash, just let me know when.

Type 3 hardcoat for these.

We don't yet have the capacity to support custom colors!


As an update, my model was handed off to Dan, and he came back with an actual  product that can be produced. (Hey Ryan, you can't make that cut!) We also added a .020 wall down from the parting line so that sharp edge doesn't roll over in tumble process. We need to integrate the Ambi portion into his model and then I will post some renders with the new feature set.

We also made the trigger guard much larger and more squared off to flow with the lines better, and support those wearing gloves.


I have several Tribe Tactical nut sacks on the way as I was made aware that they have some issues with specific dovetails. I want to make sure everything works.


I think we have made good progress so far considering it's been only 15 days.


Cheers!

Ok so I figure the first 100-200 will have a specific SN ARF-001  or something.  If we can manage it we may be able to reserve numbers....

If we can manage it.


Let's see how the pre-order plugin works. And go from that point.

I appreciate everyone on this, we are small fry right now, and this is a lot of fun for our little team.

I run all my uppers on my M16, including my FM-9D.   And will run the Lima Six on it.
But this lower is very interesting sounding.  I think I’ll have to get in on one.
I was not really that interested in an FRT or Super Safety.   But I did shoot a friends SS this summer and was surprised at how well it did.
I’ll see if I can find a steel Hoffman SS in preparation.
Are they available anywhere?

Fudd arms has had buy one get one free with code "1984"

As far as the blackwidow 'dual feed' lower goes....

I have several tribe tactical and they all have wide spring clips that have to be shaved down (or you can buy replacement more narrow spring clips from them). Generally tribe is no issue at all for dovetail and i have several of the Type 2.

Surplus 200rnd plastic porkchops. No issues across board.

Its the Raptor Tactical nutsack ive had issues with. The retention tab is plastic and not very positive pressure. More importantly, the dovetail itself would not lock in deep enough at all to even lock the tab to save its life. Simply too thick and gets stuck 1/2" or so out. Sample size of one.

Just my 2 cents, but wouldn't make the lower to fit raptor tactical because probably would make the other types too loose/wobbly.
