I’ve watched videos on the DRS Tactical and they all say the regulator pressure and hammer spring can only be adjusted by removing the stock and chassis. My DRS has an adjustment wheel on the left side precisely where the hammer spring adjustment is located. I went back and looked at videos that were only a couple of months old and they don’t show the adjustment wheel. I believe FX has upgraded the DRS Tactical and made the hammer spring externally adjustable. Not sure how it works since the manual is for the DRS Classic. 
FX DRS Tactical Factory Upgrade
- Thread starter Bigbaby
- Start date
As fx does. They'll sell all the parts they've initially made for anticipated demand in the Initial production run and the guns will be upgraded going forward but the early adopters get had coming and going and get sold the upgrade. I had this with my m3 impact and the power block.
This is why I tell everybody considering an fx to never buy a first year model... Wait and you'll save a few hundred dollars in some instances with the upgrades and decrease in hype-pricing.
I like fx but they're a bit predatory in the south African YouTube infomercials and rolling upgrades.

I wish they would at least include a manual that includes this model. My hammer spring will probably remain untouched since it comes tuned and accurate with the JSB Kings.

You can use the hammer adjuster to tweak your velocities as the temperature and humidity change. A worthwhile addition. The hammer adjuster on the later DRS's has a spring and ball detent that gives 15 positions (clicks) per complete revolution. That means about 0.067mm of hammer spring compression difference per click. Turning the wheel clockwise increases compression, anticlockwise reduced compression. That amount of spring change is very close to what you get with each click on the Quick-Tune Micro adjuster on the Impacts, Panthera's, and the new Leopard.

I have quite a few airguns including half a dozen FX PCPs ranging from my first, a Royale 500, to a recently acquired DRS. I shoot them all in stock factory configuration and have never felt the need to chase upgrades and accessories, I buy what I need. Have an Impact MK2 and have been very happy with the performance.
Don't think that FX is "predatory", they advertise like most companies do. Is it bad that they're successful?
Waiting for any new product to be proven is good advice, and, yeah, competition and new models will often reduce pricing... if other factors don't force increases. In checking several airgun sites, FX pricing seems to be competitive with similar models from other vendors.
I for one, appreciate that FX is constantly improving their products to keep in step with customer demands.
For example, my take on the FX Impacts is that the original started out as a 33 fpe (in .22) pellet gun. The MK2 was released as a pellet gun with increased power (45 fpe) for shooting slugs. The MK3 is a slug gun that shoots pellets and the MK4 is primarily a slug gun. Flexibility in configuration, tunability and serious increase in power. FX could have just coasted on their laurels (my new AA S510 has not seen a real performance improvement since it was a S400 - just the name and some cosmetic changes) but made changes as needed to stay current.
Just my two cents.
Cheers!

I do agree with all your points and I should clarify predatory isn't on fx. It's on their main sa salesman that doesn't disclose his financial interest in all the products he's showcasing or that it amounts to an ad with access to prototypes and select components and highlight real shots. It's great equipment and you too can shoot like that but it's more complicated than an aspiring marksman might think.
I will also agree that it's good they update, but they should provide some sort of upgrade program within a limited window for specific serial number guns at as close to cost as possible on some things.
I also agree they're most enjoyable stock. I feel like my m3 was almost ruined by aftermarket and power increases for a year or so. I got those issues squared away and the fault is my own.
I wasnt clear and was writing as passenger on the way to a job.
