I'm spending next years tax return.

Think about getting a Armalite M15A4(T) upper and building the lower.
I have two stripped lowers collecting dust.

Is the chamber a .223 or .223 Wylde chamber? Yes I know the difference.

How do they shoot? Can one, with proper loads get out to 600 yards and beyond, assuming I stay away from Rockstars and Expresso?

Are they good enough for F-Class Target (F-T/R)?

Someone is bound to ask what I'm going to use it for.

Don't know right now. Ego inflation or deflation depending on how I shoot.
Long range popcan shooting. Varmint hunting if I can ever get over the Cascades to the desert.
I really enjoy long range blasting.
The only rifles I have that get out that far is a 300 WBY and a 270 WCF. These are hunting rifles not dedicated long range rifles.

Thanks
