BRN-180 Fusion Lower Progress

Friend had some free time on his VMC so he agreed to make a lower to see how it looks in real life.

First couple of operations are done and it is starting to look the part. Another cut along the bottom following the magwell will just about finish the side profile.

What do y’all think?

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?

AR180S Pistol Grips Ready To Ship

Well I have 3 ready to ship.

I have reworked the model and done modifications to my printer and I am happy with how they are printing now.

I have also decided to put them up for sale and will print and fill orders as they come in. That might take awhile to fill as they take quite some time to print. 18+ hours to be exact.

These can certainly be used as is but really need to be sanded, polished, possibly even painted.

Here is an early prototype that I sanded and rounded the edges then polished.

First 3 will ship right away, first come, first served. Just click on the link at the top of the page to take you to the Shopping Cart.

I am really looking forward to getting some pictures of how your pistol grips turn out!
