The FX Crown MKII with GRS Green Mountain Laminate stock is one of the most customizable rifles on the market because it features the adjustable AMP regulator, Superlight STX barrel system, external hammer spring adjustment and transfer port adjustment, and that's not even half of the interesting features on this PCP. It's no surprise that the Crown has quickly ascended to the top of the high-end market. A long list of innovative and interesting features make this a popular choice among those looking for the best airgun money can buy.

This new model comes with an exclusive GRS laminate stock from the world-renowned Norwegian makers of first-rate rifle stocks. It marks the first time they've made a stock for an air rifle, and it offers shooters a broad forearm, tool-free adjustments, and an angled and offset ergonomic GRS grip, in addition to the adjustable buttpad and adjustable cheekpiece.

Fill the rifle to the 250 BAR (3,625 PSI) max. and enjoy long and consistent shot strings from the 480cc Carbon Fiber air cylinder. The two-stage, match-grade trigger is fully adjustable for precise shots. Simply mount a scope onto the integrated Picatinny optics rail and hit the range.

Housed within the barrel shroud, you'll find the latest-production Superlight STX barrel, which weighs in about a half-pound lighter than the previous versions, yet offers increased rigidity and enhanced performance. The flagship barrel from FX allows the user to not only change calibers on the same rifle with the appropriate caliber change kit but also allows for different liners to be used in the same caliber to provide enhanced performance with specific ammo.

Spend some time with the FX Crown MKII with GRS Green Mountain Laminate stock and see why it sits upon the airgun throne for superior long-range benchrest or hunting results.

Things I liked:

This is by far the most accurate out of the case, and I say case, because the Crown Mark II GRS comes with a very nice hard case, PCP air rifle! The GRS stock is beautiful and very functional needing no tools to adjust the cheek comb and recoil pad. I think the stock bottle is great. I get 200, yes, 200 full power shots from my .22 caliber Crown! Mine came with the new, 2022, rear power adjuster that adjusts from 0-24, instead of the confusing seven fixed levels! The side lever cocking system is the smoothest ever. The included suppressor is really quiet, more so than my DonnyFL suppressor and I also love the DonnyFL suppressor. The new 18 round magazines are great and simple to load. I find it loves JSB pellets, the 18.13 jumbos, the 15.89 Diabolos and my favorite, the 15.89 JSB Hades. It also performs great with AIr Arms Field Diabolos in 18 grain. The two stage match trigger is crisp and light. No need to adjust it. It is under 15 oz. I also have no issues loading single pellets.

Things I would have changed:

It would be nice if it came with an extra magazine. Actually, I would like to see a smaller capacity magazine. Ten shots would be nice. As is, I just load my magazines with 5, 10 or 15 pellets. As far as the rifle goes there is nothing I would change. I believe the user manual could be more detailed. I have had to rely on YouTube to learn many aspects of tuning the rifle.

What others should know:

The value you get for your money is great. This is a heirloom air rifle.

Things I liked:

Laser accurate, virtually all different style pellets seem to shoot the same, grain weight being the only variable that changes POI, laser accurate! Yes, LASER ACCURATE! Love this rifle and the GRS stock is worth every penny. Unbelievably quiet for such a powerful rifle. I'm sold on FX.

Things I would have changed:

For this price, the larger capacity bottle and at least one spare magazine would seem appropriate.

What others should know:

The GRS really is worth every extra penny, completely different grip, very nice. Only one issue with the entire setup, the GRS stock should be hogged out just a little bit more around the fill port. The FX quick disconnect is the only fitting that allows an airtight fit for filling, I've tried some of the other brands, the diameter of the quick disconnect collar is too large and they won't fit on the fill nipple, due to interference with the stock, for an air tight connection. Just use the FX unit and no problems.
