Way cool! I thought about doing my 9mm as a sbr, but I will be putting a supressor on it so I think instead of doing 2 stamps I will just make the supressor " permanent" by doing a blind pin on an 11.5 inch barrel and use the supressor to make up the rest of the 16" length.
I have a lot of the small parts for AR type rifles if you ever need anything.
Thanks for the parts offer. ABQ Guns had the dent pin I launched. I bought a couple extra ... while I was there.
Form 1's and Form 4's are a rabbit hole. In addition to the Form 1, I have a Form 4 for a 30cal going on too (Christmas purchase that was backordered, and just came back in stock). I will suppress the 9mm, but not right away.
