[SNEAKY PETE]

Old Sneaky here: I decide that it has become necessary to obtain a new lower for "F" class primarily and maybe some varmints and pigs(seldom). I can put together a lower if I choose or purchase the total finished product or partially assembled minus the trigger (which I have plans for anyway). BUT here's the Kicker !!! I have Upper receivers havng different sized holes-- The Origional SP-1 with a big hole and the Nat match and the target uppers with small holes both using adaptors to fit a Colt SP-1 lower. Looking for advise/opinions. THANX SNEAKY
