ar-15 cal.options?

i have just built up a ar in 5.56/.223, is there any other cal. options i can do with this lower,with just a bolt carrier/barrel change? or is one better building seperate guns all together (never hurts to have more guns,just harder to hide from the misses).

    Their's few out there that just need barrel/bolt and mag changes The 6.8SPC was made to do just that while adding more downrange punch than the 556. 300whisper and blackout are also taylored to work with in the AR platform, as well as a bunch of others that have been necked up or down to fit. What use are you looking for from this gun?

    Re: ar-15 cal.options?

    i built it beacuse i have wanted one for about 15 yrs but never wanted to drop the cash, then this one came along cheep so i splurged. i figure it a good shooter gun one can afford but i think it could use a little more punch. so i was thinking about a 7.62x39(still pretty cheep ammo)i dont know about the 6.8spc or "blackout". but i dont want to go to the point it gets to pricey to shoot.

    For inexpensive shooting, the 7.62x39 is pretty economical. For all around performance in a standard AR, the 6.5 Grendel is tough to beat.

    If you hand load it doesn't really matter as they're all fairly cheap to load. If you're buying ammo off the shelf stick with the 223 or 762. Be careful with the 762, alot of the cheaper ball ammo builds up crud in the AR shockingly fast, and can be pretty corrosive as well.
