looking to start my 2nd ar build.this time i want to do a SPR type ar. 18'' barrel,higher power optic ect,ect. id like to start with the barrel and would appreciate some advise on manufacturer . what i really would like to be able to do is pick up a barrel/bolt combo. i was looking into noveske or wilson combo but it seems like a long wait to get. thanks

Another option is Compass Lake engineering, you can order the bolt too. You can also choose which blank you want machined, Douglas Krieger or Criterion.

bead blasted Krieger with bolt is $540

I went with an AR Performance Barrel. Haven't used it yet, but I have heard people sing praises about them, and I was able to get what I wanted for a decent price.

I got mine with the matching bolt.


I just can't decide if I should use the Seekins billet set for it or not :confuse

Edit: As a note, the threads are not standard for 5.56/.223. They are 5/8-24 and ARP has 5.56 brakes for that. I was willing to jump on it after hearing/reading about the barrels.

ive heard good things about the w.o.a barrels but the wait is killer.c.l.e is new to me ill have to give them a call . what cal. did most of you go with . im thinking i want to stay in the .556 with a mid length gas system but with the .223 wylde cambering . they are both readily available in this anti gun climate. btw thanks for all the good advise guys i really do appreciate the experienced help for my project. feel free to share pics

Sinclair or ADCO usually have the WOA barrels within a month.

I built my spr in 5.56 with a Blackhole Weaponry barrel.

Rainier Arms has a couple selections for your intended purpose. May want to check out Ballistic Advantage also.

You can also check out Precision Reflex, they carry alot of .mil SPR parts and SPR parts in general. They also carry plug and play mk12mod0 uppers if you are interested.

The ar15.com SPR/Mk12 threads are great resources to get ideas ( and funny bickering at times ). The clone nazis crack me up <EXTERNAL LINKS FOR EDUCATIONAL PURPOSES>
