Had to go to the cabinet factory in Monroe. As I was leaving I saw a sign that said "SIC - Guns/Ammo"
Natch... I HAD to drive around until I found them. (169th and Tye St. roughly; 14253 169th Drive SE #455)
Went in. It's a full gun store, but they have an emphasis on builds (parts, or they will do it for you)
Seems like they stock a lot of build parts (including LPK's and individual parts)
Transfers done there too. Suppressor sales.
They say they have great sources and can find guns faster (probably) and find "unicorn" guns that you may have trouble finding.
Nice folks.
Seem like pretty good prices.
They get the jukk0u seal of approval!
