I am wondering what you think would be the best option to get having in mind cost, practice and fun?

plain ole 5.56 chambered upper.

^^ +1 5.56 is the way to go.

5.45 x 39mm.

Plenty of low-cost blasting ammo!:thumbsup:

9mm is only about 20% less than .223 and it's no rifle cartridge. You also can't drop in a 22lr kit.

22lr is cheap, but a Ceiner kit will work fine in a 5.56 gun.

This gives you best-of-both worlds.

5.45x39 is a good option if you have access to a range that doesn't regulate against magnetic ammo.

.223 w/ conversion kit. Gives you the flexibility of practicing with your rifle for cheap.

Many advantages to a plain 5.56 upper for the first time buyer.

My next build is going to be a 9mm, so that's what I put... :thumbsup:

I am leaning towards a dedicated .22 upper, because this way I can have a fully functional rifle.

What's the price difference between .223 and 5.45?

Practice what you fight with. 223/556 all the way.

Shooting .22lr is totally different than 223.... you can fire .22lr as fast as possible and get them all on target... if you pull the trigger the same rate, your groups and hits will be all over the place... .22lr is fun tho, but i really don't think you can equate training with .22lr the same as training with 223/556

FWIW theres a thread just a couple up from this one with a few people saying .22lr kits are prone to out of battery discharges

What's the price difference between .223 and 5.45?

about 25-35c a round.

what do you already have? If its your first, I say go with 5.56. Make sure its 5.56, because that gives you the option of running .223 through it, as well as having the drop in capability of the .22 kits. If you get a .223 upper, you will be limited to .223 and .22 kits.

ETA: I see one of your poll choices is .223/.308. You will need two different lowers for this, so it is really two different rifles.

5.56x45 then get a dedicated 22lr upper.

I would prefer the plain old 5.56. It is not on the choices you provided. .223 is no 5.56 when it comes to power.

Go 5.56 like everyone is saying and be happy with it. You can do all kinds of mods to it, range from 40gr to 75Gr with a 1/8 twist, and you can do a .22lr conversion with it. Chrome lined for ease of cleaning after the .22 conv.
