FX DRS Classic, Synthetic 600

The FX DRS Classic Synthetic 600 is a regulated PCP air rifle in .177 (4.5 mm) from the first generation of FX's DRS platform, here with a 600 mm barrel and a synthetic soft-touch stock. The rifle is 1027 mm long and weighs 2650 g, holds 260 cc of air at 230 bar and is loaded with a sidelever from a 16-shot magazine. FX quotes up to 26.4 J for the FullPower version.

The mid-length version with a 600 mm barrel is a good compromise: the longer barrel and 260 cc give more air and energy than the 500 model, while the rifle is still manageable in a hide and on foot in the field. The black synthetic stock handles damp without any care and gives a secure grip with its soft-touch surface.

APB barrel system, AMP regulator and STX liner

Five features that define the DRS Classic:

• Air around the barrel (APB): The air reservoir sits as a tube around the barrel instead of under it. That gives a slim, traditional rifle profile and a stiff barrel assembly that does not shift in relation to the scope.
• Externally adjustable AMP MKII regulator: The regulator keeps the working pressure constant through the whole fill and can be adjusted from the outside, so you can fine-tune it to the ammunition you shoot without taking the rifle apart.
• Interchangeable STX Superior liner: FX's Smooth Twist X liner has rifling pressed in from the outside for low friction and a good seal. The liner can be changed if you want to try a different twist or change calibre later.
• Modular power plenum in magazine style: What looks like a classic rifle magazine under the stock is a 16 cc plenum that gives enough air per shot. The plenum can be swapped for a larger one as an accessory.
• Adjustable two-stage trigger and 11 mm rail: Both stages of the trigger can be adjusted, and the scope mounts on an 11 mm rail. The muzzle has a 1/2" UNF thread for a moderator.

Maintenance and safety

• Only fill with clean, dry compressed air via the fill probe, and do not exceed 230 bar.
• Check the O-rings at the fill port and magazine regularly, and replace them when worn – a leaking O-ring costs both air and consistency.
• The synthetic stock needs no special care – wipe it with a damp cloth after use in rain and dirt.
• Store the rifle unloaded and out of reach of children. Check the air rifle regulations in your country before purchase – rules on power and age limits differ across the EU.
