The reason I wanted to use a post ban lower is because if it gets screwed up big deal, I will simply try another! If a pre ban Small holelower gets screwed up it is gone forever!
I have a couple of pre-ban Colt SP1 type rifles with slab sided lowers, The problem is they are all large hole! I want a small hole to replicate a very early rifle.
Also I am aware of the law with regards to pre-post ban assembly requirements, I have no intention of doing anything that is not legal,
I intend to use a custom 1:14 inch twist barrel with the bayonet lug neutered with a permanently attached Fake duckbill F/S from Kurts Kustom to give me the retro look, but still follow the letter of the law!
