The FX Royale 400 is the result of years of research and testing as FX has continued to perfect and innovate what to expect out of an air rifle. The Royal series represents their finest sporter air rifle with features and quality that can only be found on an FX airgun.

The heart of the air rifle is the superb Royale breech block which has an internal regulator and valve system that provides consistent shot after consistent shot. The side cocking lever is effortlessly smooth which rotates the 12-shot rotary mag (16-shot in .177 caliber). The barrel is shrouded and moderated to suppress rapport.

The barrel is FX's state of the art FX Smooth Twist barrel. This barrel is an innovative barrel design that is essentially a smooth bore barrel for the majority of the length, with an aggressive twist/rifling at the end of the barrel to introduce stabilizing spin as the pellet leaves the barrel. The result is world class accuracy without diminishing power. This accuracy has been proven time and again at competitions throughout the world.

FX Royale 400, Synthetic Features DiagramOur Royale 400's have been upgraded with 480cc carbon fiber air cylinders. These have a max fill of 250 bar (3600 psi) which allows for more shots per fill than the standard Royale 400 aluminum air cylinders as well as lightening the weight of the gun. If you don't want full power the FX Royale 400 is easily adjusted to lower powers using the 3 step power adjuster on the left side of the breech. This will reduce power and extend your shot count.

The Royale 400 air rifle features an exceptional fully adjustable two-stage match trigger. Out of the box you'll find the first stage to be very light with a clean break (factory tuned to just 12oz!). The stock is synthetic, coated with a soft touch all weather coating that provides a great feel and grip. Note that the synthetic stock is a right handed only thumbhole stock. Left handed shooters will need to consider either the walnut or black pepper laminate stocks, both of which are ambidextrous. The stock is very well balanced with a balancing point located just under the breech, making it easy to shoot off hand.

Note: Higher calibers are available in this series of airgun. The FX Royale 500 is the .25 caliber version, and the FX Boss is the .30 caliber version.

This is a fantastic rifle. Mechanics and technology are great. Perfectly accurate, very smooth operation and craftsmanship is superb. However, then ergonomics suck!!!! The stock is made for people with small hands. I have big hands and my thumb does Not go all the way through the thumb-hole to completely grab the grip. Thus, I am disappointed and cannot shoot a $1500 rifle comfortably.

Pros
Superb accuracy, very quiet, power adjust, smooth operation, great craftsmanship.

Cons
Terrible stock! Themb-hole not big enough to completely grasp the grip. Can't get acomfortable grasp. Stock made for people with tiny hands.

First of all I was hesitant to order such an expensive item without having seen the gun before but airgundepot return policy made this a no brainer! So I preordered the gun and about a month later the FX wa delivered to my door...
The rifle is a work of art! The attention to detail, engeneering and workmanship are the best I have seen so far in an airgun (very much in lign with the quality of the "diana model 100" that I bought more than 30 years ago).

THE WEIGHT: The gun feels lighter than expected (I attributed it to the carbon fiber tank and to the syntethic stock) by the time I added an high power scope the weight is perfect most of the guns once outfited with a big scope seems way too heavy to my taste. So for me I got the perfect combo.👍

THE STOCK: I'm 6 1 and have large hands the grip fit me perfectly overall the closest in comfort to a match grade rifle. 👍

OPERATION: The side lever is smooth as butter and requires little to no effort to operate👍. The trigger is litterally match grade quality👍 Accuracy with the right pellet this is amazingly consistent. At 25 yards sub 1/4 inch group all day long at full power👍 the Power wheel is a nice bonus, this allows 3 levels of power adjustment as well as sound level control (low power makes the gun almost silent)👍 The 400cc tank along with the regulator and the "factory tune" allows for a ton of shots per fill👍


Pros
Overall superb in all respect: built quality accuracy long shot string backyard friendly When needed comfort For me this is the perfect example of how airgun should be made no room for error and FX did just that no error, no shortcomings and no flaws. To me it is perfect in every ways.

Cons
None to speak off. OK it is a bit pricy but you get what you pay for.
