YES! My philosophy about the whole thing is buy what fits, works, great deal falls in your lap, or whatever. Don't feel any need to stay in the $1200 MSRP base ceiling. Between used, sales, discounts and such, there is no reason to pay retail for optics unless it is top tier. Rifles are hit and miss, ergonomics come into play. Some people can have a out of the box __________(insert name of bolt gun) fit like a glove, others need spacers, risers, and pixie dust to get even a mediocre cheek weld. It's the MSRP that makes it tough. My wife's rig (PWS Summit, KRG Bravo, Athlon Midas Tac) total purchase price was just under $1200, but the MSRPs are close to double that.
The short version is there is only a handful of rifle models and scopes you can run in base class, which no one cares about anyways.
For the same or a little more, you can have a much nicer rig.
I presume the intent of Base class is to encourage new shooters to bring what they have and not be intimidated, but I fear it has the wrong effect. Unlike IPSC and some other disciplines, you won't be left in the dust if you venture outside of new-guy Base territory. Every new shooter I have seen at a match is encouraged to mess with every rifle in the squad and get an idea of the gear and all of the what's and why's.
Winning in Base class doesn't get you any more prizes than coming in last in Open. Unless you are top three, young, old, or a lady, it's all raffle. My first match was a large NRL22X match that I was about 2/3 down the Open rankings, I still came home with a 40% off a XLR chassis certificate. The dude just under me won a free TBAC 22 can.
