That'll work Lynn. It's like a Chevy Biscayne

Bushmaster is not the old Bushmaster (that's Windham Weaponry now).

I believe the barrel will be a 1/9" twist so the heaviest bullet you can use accurately will be the 62 gr bullet in the "Green Tip" M855 round.

Any lighter bullet will do just fine too.

Many types of ammo out there, hollow point and soft point are good too. Us civilians aren't bound by any of these international accords.

Magazines are everywhere and the prices for them, right now, are excellent. All you have to concern yourself with is quality.
Magpul Pmags are good to go as well as Brownell's metal magazines. You can get these direct from Brownells.

The gun is just like a Lego set for adults now a days. All kinds of things to bolt on them, top and bottom. You can mix and match just about anything on one to suit yourself or just leave it 'as is'.

Down the road, you should get a small supply of the parts that are easy to loose or wear the most.
