The ONLY special about Pete's RRA lowers are they say "US PROPERTY" which only his will say that.
Thats exactly the reason I dont buy from him. I DONT want mine to say that. Mine arent "US PROPERTY" they are MY PROPERTY!!!
A rock river lower from Pete will be the same quality and finish of a RRA lower from any other dealer... so unless the special inscription is appealing to you, buy from someone you like, or who has the best deals.
On the finish, I would have to say, that the RRA lowers I own have a better machined finish than my Bushy's or Colts.... and the final anodizing looks better and is more consistent on RRA.
Take all that into account, and I will still prefer a Bushmaster lower over any other. Just partial to the snake I guess.... and I like to give Bushy my business whenever I can. When it comes to barrels, almost all of mine are Bushmaster.
I know Bushmaster uses a hard coat anodizing on their lower receivers.... does anyone know if RRA uses the same process? I think this might have been one thing that set them apart.
In any case, you should not be dissapointed with pretty much any lower out there on the market today, except for Hesse. (but I think they finally bit the dust until the next bankruptcy)
