Hits reciever. - Gear Head Works Tailhook Adapter to Fix Sig Spin Brace

I was weary of getting this but after seeing on gearheads Instagram that the mod 1c would clear the reciever I went ahead and purchased. The adapter hits the reciever even without the brace on. I'm hoping I can machine away enough material to get it to not bang in the side when closing the folding stock but this shouldn't be a thing in my opinion.
