Re: RRA PP or WOA Upper?
I have an 18" WOA SPR barrel that I run a GEMTECH G7 can on. It is mated to a SPIKES upper and lower, with a Geissele SSA trigger, and this rifle is a tack driver.
I am in the process of building my second WOA barreled AR. In fact, they are waiting on the free float tube and then they are sending it to me. I ordered a 20" Varmint Upper, and talked to John on the phone to spec out the chamber. This rifle will be my work mule, where I routinely shoot steel out to 600m. We have a contract with Black Hills, so I will be shooting their 77 grain SMK loads. The 20" upper will be put on a LMT lower, Geissele Match Trigger, Magpul PRS, and if it shoots ANYTHING like my 18"... I will be completely pleased.
Work gave me a case of 69 grain Winchester Lawman BTHP... so, this is the load I have been running in my 18". This rifle has an SWFA Super Sniper fixed 10x42 on it, mounted with the Burris P.E.P.R. 30mm mount.
I rappel with this rifle, shoot from the bipods... and have verified the ballistics on this 18" with the 69 grain Winchester Ranger loads, from 50m all the way out to 600m.
I can only imagine how the 20" will shoot with the match trigger.
Give WOA a call... speak with them. I would urge you to strongly consider them... heck of a good company to deal with, but you will have to wait a bit. You do get what you wait for though.
Cheers!!!
