Description:

Laylax PSS10 High Pressure "Neo" Piston

Part of Laylax's Perfect Sniping System, this piston replaces the stock plastic piston fitted to the Tokyo Marui VSR-10 range of rifles.

This piston improves upon the stock plastic piston, with lightweight aluminium construction body, dual plastic support rings, stainless steel base, damper piston head and a choice of damper shaft or grub screw mounted on the piston head.

Positive aspects of the product (pros):	Strong, reliable, well designed, improved compression
Cons:	Plastic support rings can deteriorate slightly with aftermarket sear sets

This piston offers a selection of improvements to the stock plastic piston fitted to the VSR series, and you will be your rewarded well for parting with your cash.

The piston body is constructed of aluminium, anodised an attractive reddish pink tinge. Lighter than some offerings on the market, the reduction in weight over other materials allows more rapid acceleration of the piston when the rifle is fired, supposedly reflected in quicker firing times after pulling the trigger.

A stainless steel end cap provides a much stronger and more resistant section for the piston sear to hold onto when cocked, particularly important once aftermarket sears of harder materials are used.

Two plastic support rings give the piston contact with the cylinder wall, helping to maintain a central position for smooth action. However, when using aftermarket sears (generally of high spec steel) the plastic is no match, and does get gradually worn down to some extent. I have found that it does reach a point where no more material is removed from the piston, though this may compromise some of the stability of the piston. I would advise cleaning out the cylinder assembly after the first 5 uses or so, as a fair bit of debris does collect around the piston o-ring.

Moving on, the piston head incorporates vent holes to aid in spreading the o-ring to create an optimal seal when travelling forward. The head also has an inbuilt damper pad to reduce some of the shock and noise made when the piston contacts the cylinder head upon firing. Finally, two options are given with regards to the centre of the piston.

An air brake can be fitted, with the aim of reducing the speed of the piston somewhat, and thereby reducing noise at the supposed cost of a slight fps drop. If the air brake is not to your liking, a grub screw can be fitted in its place, making things noisier while improving power. I would like to add that I never really saw any significant difference in fps regardless of which part was fitted to the piston, and I have chosen to keep the grub screw fitted.

Overall, a good piston with a multitude of features that make it a good choice over the stock piston. The internal diameter is also more suited for aftermarket springs, allowing smoother operation.
