I`ve recently purchased a LN Bushmaster A2 ar15 with 20"heavy barrel....I`ve decided that the 20" HB is to heavy and I`d prefer a 16" LIGHTWEIGHT barrel...I`m looking to make it a carbine length gun......Your`re probably going to ask why I didn`t get a carbine....I just couldn`t pass this up at the time...My first AR15...

If I change the barrel will I have to headspace it again?

What Mfg. makes a reasonably priced 16" barrel...I`m looking to do a little range work at 100/200 yds but more interested in tactical.....Whats your suggestion and where do I buy one...Thanks Jim

Ya that`s the way with the guns that you can customize...I`ve been messing around with guns for a long time and
It`s always the other side of the street is greener...This is my first AR and this gun looks to be one that one can
spend piles of cash on....

I always head space my new barrels. You are suppose to headspace the bolt with the barrel. They wear together and I have never heard of them being headspaced from the factory. If you ever called and said hey I bought you barrel should I headspace it they will say yes 100% of the time. I have never had a barrel fail a check , but if you get a set of go/no go gauges you could turn and sell them in EE for pretty close to what you paid. DEL-TON has pretty cheap light weight barrels that work great for the price. I could not decide between 20" or 16" so I just shoot both.
