3 x 4mm Spacers (the amount you can use will vary on the spring used, eg the M150 can only use 1 spacer and M140 can use all 3)

Please Note:

- Due to the rear guide design, you may need to lower your sear height to allow the sear to slide over and release. If you find the piston does not release or sticks, lower the sear height.

- When using the weighted set up, DO NOT dry fire the rifle. This may cause eventual damage and is the responsibility of the customer.

- The Piston can only be used with the included spring guide.

The piston itself is a ni e piece of art...but the spring guide needs to be better.
When we cock the piston back, it touch the spring guide so it makes noise when cocking. I 've machine it to have the place to fit a o-ring. The o-ring act as a damper and there is no more noise piston /spring guide

Wow just got the “wasp”

Fantastic piece of kit and really adds something else to the SRS. Skrimshop were great, the delivery was delayed due to Royal Mail but all credit to Skrimshop as they kept me informed with the issues at Royal Mail and did all the chasing on my behalf.. Fantastic Service!!!!!

I recently received my SRS WASP and I am blown away by its performance.

It has done exactly what it set out to and allowed me to fine tune my rif and make it virtually silent (the videos do not do it justice, it’s damn quiet!) and it’s so easy to install and get to grips with.

Huge thank you to Sniper Mechanic and the guys over at Skirmshop for the quick delivery and great customer service.

Will be using this shop more often for sure.

Brilliant kit. Very well made and looks and feels quality.

When using full airbrake combined with other mods to my 16" it was quieter than my MK23.

My setup:
420mm TNT barrel with TR hop rubber
Prowler rubber nub
Heavy sleeve with full airbreak
Rapax 2+ spring
Getting 2.2J on .48g hitting 250ft+ easily.

Also comes with spring guide spacers so you can tweak the joules as needed.

Well worth the money.

Very good quality, very easy to put together and install. Probably the quietest my SRS has been, very consistent FPS.

Awesome simply simple awesome

Unreal piece of kit, gave it a proper test today in game. The seal is you get from it is second to none, massive improvement on range and has been lifting .45 gram bb’s like they are nothing. Hands down the best piece of kit I’ve ever purchased.

| Oliver C. 26-01-2019 01:01

Stunning and bar far the best investment I’ve made

The W.A.S.P piston is perfect.

I have been using the stock piston with a air break piston head in my 2018 model 20” sport line SRS and was absolutely in love with the performance of the gun. It was quiet, it was fairly consistent and all round brilliant. Then along comes the notorious W.A.S.P piston. It was recommended to me by a few players I have met but being honest I didn’t know how it could improve my already brilliant setup. This is when the W.A.S.P piston proved me wrong, it takes the gun to the next level, it’s silent and perfectly consistent, with the interchangeable sleeves (light, middle, heavy) to change the weight of the piston it take all of 5 seconds to reduce or up those joules. The cup creates a flawless seal, giving you that consistency. Assembling the piston is just as easy as taking the SRS apart (super easy), along with the interchangeable sleeves you also have different air breaks to go on the piston, a full, tapered, and plug.

The build quality of this piston is flawless I am unbelievably happy and would give this a 10/5 if possible. Thank you very much to SniperMechanic for designing and producing a fantastic part, which I believe is well worth the small price for the performance.

Having purchased the W.A.S.P set for my VSR , it is very noticable that there has been a step up in design and presentation from Sniper Mechanic .
Out of the box you are greeted with individually wrapped componants that come in a clean white box emblazen with the Sniper Mechanics / WASP Logo

Installation wise , there is a useful link that guides you through the proccess clearly and was something I would recommend checking out - for this is not your every day piston .

The build quality of the parts can be felt in hand and all parts seem to be very well machined form high quality materials - I have no doubt that this will stand the test of time , even with higher rated springs.

My initial testing has shown the sealing (not that there was an issue with the stock piston) and smoothness of bolt have increased notably. More over , the noise (muzzle report ect ect) has decreased to an almost inaudible poof!

Overall :

5 Star Company (Well done Skirmshop)
