BRN-180 Fusion Lower Update

I ran into some problems with my earlier designs. Squaring off the rear of the receiver would leave no room for the web of your hand.

I had not realized this and was working on a Gen II version that had a 180B style rear end. This had the same problem as Gen I but also would not allow the BRN-180 to drop down into the receiver at the back.

I started fresh this morning and left the rear end alone and just modified the front to resemble the AR-180B/Nodak NDS-18S.

Astute observers may have noticed I also modified my pistol grip to fit on a standard AR-15 mounting point. I have had this request from some of my followers on Instagram.

By the way if you are on Instagram give me a follow. I post a lot of other stuff on there that you might like. Look up BigRix, the same as my Youtube channel.

Designing a Lower in Fusion 360

I just couldn’t help myself but to design a lower for the Brownells BRN-180. Grabbed a file off the internet for an AR-15 and modified it to look like an AR180B.

I love Fusion 360, it allows me to bring my thoughts to life. Now I just need something like a Tormach and I could make it reality.

This would require no proprietary parts at all.

What do you think?

Quick Update

I posted about my AR180B in box for sale some time back and it is up on Gunbroker. No reserve so have at it. I would love to see it go to a good home with one of my readers.

Click here to see auction.

I’ve also added the AR-180 bolt catch to the shopping cart to make it easier for those interested in buying them. You should find a link at the top of the page.

Thanks to all those who read, share, and buy my stuff. It all helps support the site and keep it running.
