It's always interesting to read the opinions that come up when certain types of questions are asked. Equipment decisions are always fun to read especially if there are rules by which you have to abide in order to compete.
Here are the rules for PRS Production Class:
“Production Division combined rifle and scope MSRP as listed on the company’s website shall not exceed $3,000 USD, the rifle shall not exceed $2,000 USD and the optic not exceed $2,000 USD.
Production Division rifles are not permitted to be altered or improved in any way from the original factory configuration.
In an effort to prevent exorbitant costs for beginning shooters, Production Division round count will not exceed 80 rounds.”
In that vein, here is another entry into the PRS Productions Class with everything being discussed:

There is the Tikka and the GRS mentioned above and the Ruger RPR, all of which are made for this class participation. There are others I'm sure.

Although the terms competing or competition gets bandied about without care occasionally, the OP simply states that he wants to 'jump in', not necessarily be fully competitive right off the bat. With that in mind, two things can be considered just for getting started and to get your feet wet:
A good bipod, handled properly, can be very competitive, ask the F-TR folks. So a forend which
isn't 3" to 5" wide can certainly be considered in the beginning. The SEB Joy-Pod come to mind if you want to be slightly extravagant. Otherwise any of the better bipods can be suitable.
If a front rest IS desired, there are replacement bags available to accommodate nearly every forearm every created. No, the 'sporter-type' bags may not be perfect for controlling the rifles movement but it is a start nonetheless.
PRS will require a DBM system of some sort but remember you will need multiple magazines for convenience and speed.
There are challenges to accommodating all of the various forms of competition especially if the forms utilized in those competitions run slightly contrary to each other. The idea is to welcome new people, get new people started and help bring them along so that they feel that they are a part of the competitive shooting fraternity.
