Am I able to convert this upper from a direct gas to a gas piston? I am aware that I must change the fore end of the upper to do so, but would I be able to use the adams arms kit to convert?
Answer:
Yes. You can convert any AR-15 upper to a piston system using our Adams Arms kit, including this one. You will not need to replace the upper receiver, but you may need different handguards.
on Luth-AR website it says the barrel is 5.56mm so can this shoot 5.56 and 223?
Answer:
Yes.
In the description it says it has a .223 BCG. Is this correct for a MARK12? I'm currently looking for an 18" upper barrel receiver that will shoot 5.56x45mm. I don't know if this .223 BCG will handle 5.56.
Answer:
This bolt will shoot both .223 Remington and 5.56 NATO ammo, in addition to .300 BLK.
Is this 556 and 223?
Answer:
This unit has been updated to use both .223 and 5.56
