Hiro. Okay ladies and gents, I got the itch and decided to delay a pistol and build another AR15. Thinking of keeping this one 5.56. Really digging on a spiral fluted barrel. However that's to be decided. Barrel will be 1/8 16", no front sight post, mid length gas port. what's a good brand that won't break the bank, I.e. $250 and under? I saw some Wilson barrels that looked ok and were inexpensive. Also some Rainer Arms? I know the great names, just can't spend $300 and up on a barrel. Also, looking for an upper parts build kit. Has all the hoo hoo ha ha I'll need, who and where is a good place to order those? I picked up a yankee hill Stripped upper today, and walked away on two lowers, a Anderson and an AR FIFTEEN. Never heard of either. Think I'll follow Tikki on getting an Alg? Trigger and a good lpk. I have a doublestar lpk in my other rifle and it's nice. Also a question gents, is a delta ring needed for a free float hand guard? I have no idea how those go on! Please feel free to add suggestions as long as they are feasible. Sadly I go back to work tomorrow, but I should have some goodies awaiting my arrival at home!
