AR180S Pistol Grip Prototype

Been wanting a better pistol grip to use on my Nodak NDS-18S lowers pretty much since they came out.

I used an ArmaLite grip but only bought a couple before they stopped selling them. (Sound familiar?) It also didn’t have the right shape.

Since I have been working with Fusion 360 I have been thinking of all kinds of things to design. Why not a better looking pistol grip.

I’ve still got a few kinks to iron out then I can make a more detailed print. I’m confident it would be a functional part when I am done and will certainly put it through it’s paces. It is very comfortable in the hand.

I’m diggin’ it. Anyone else?

Shopping at

I finally figured out how to add a way to link to the AR180B lower completion kits that I sell. I have created a couple pages that you see at the top of the page and a shopping cart feature. It is still very basic with just the two items for now but I hope to add other stuff down the road. This should make it much easier for folks to find these kits in the future.

Who knows, maybe some AR180B trunions and flats might end up there some day.

Drop-In Trigger For The AR180B

I’ve often thought about a drop-in trigger for my AR180B Shorty Project, The AR180S.

Reader Matthew asked about one for his Nodak lower and I had to tell him to proceed with caution because I was not sure if they would work.

I was concerned about interference with the bolt hold open assembly.

As luck would have it I was picking up an AR180B at my local FFL and knew he had used drop in triggers in some of his guns. He let me borrow one to try in my gun and I am glad to report that it fits!

What he let me use and at this time the only one I can recommend is the Patriot Ordinance Factory 4.5 pound single stage with standard trigger shape. Click here to read more about it.

I will report back after I shoot it but dry fire and function check work flawlessly so far.

The best part is, it includes KNS anti rotation pins so that will save you a few bucks. You can used the included side plates and just order the longer pins. Read more about the pins here.

Surfing around and I found that Joe Bob Outfitters has these POF-USA Drop In Triggers for $149.95 shipped and it includes an AR15 lower parts kit. That looks like a smoking deal, click here.
