So quick follow up, I contacted SA via the #provided and they got the missing parts out to me ASAP ($45 for parts and 3-day FedEx). Parts arrived this morning and I am very pleased with the results. Thanks for helping me out guys my 'frankenpistol' is ready to go!!
So I somehow managed to lose the two rectangular pieces with a hole on either end that lock the handguard in place, also the 4 screws (I know I am an idiot). The example pic shows exactly what I am referring to. Can anyone tell me what they are called and where I might possibly find...
