What is the correct designation for an A2 carbine upper with round forward assist, brass deflector with a pencil barrel?

If with a 16” barrel, that’s a 6520 “Government Carbine” upper. I don’t recall ever seeing a 14.5” pencil barrel on an A2 upper. A 727 upper would be A2 upper with a 14.5” M4 profile barrel. The 723 had 14.5” pencil barrel on early models with both A1 and C7, then M4 profile on C7 later on.

Yes with a 16" pencil barrel.

Would it still be considered an M16? Thinking of getting a retro marked lower.

Colt only used 16" carbine barrels on semi-auto rifles. The M16 carbine equivalents used 14.5" barrels instead.

6520 Government Carbine. Semiauto. Not an M16.

Don’t waste time cloning that. You can find genuine LE trade-in Colt 6520s on Gunbroker for around $1k.

Thanks everyone? What would would be the most correct PSA H&R lower for this?

Refer to the Wiki posted above, but many of them have a full auto setting with an A2 designation, so this lower is the most applicable…
