for .177, .22 and .25 NOT .30

Part fits Umarex Gauntlet 177, .22 or .25. Not compatible with the Gauntlet .30 Caliber.
This part is designed and manufactured by DonnyFL
Origin .22/.25
NEW ENHANCED DESIGN
UPDATE: The newer Origins have a screw-on barrel shroud and an end cap that is a two-piece unscrewable but the STP still fits and works without an issue. unscrew the shroud rather than the little screw shown in the video and simply unscrew the baffle washer array off the end cap and you are good to go.
Strip Stak Pak for the Umarex Origin
A six piece kit that includes an efficient multiport air stripper that strips and channels air away from the pellet to allow for a more stable and less turbulent pellet launch from the muzzle. The kit also provides baffle chambers to help remove both noise and turbulence in the air stream. The end result is a more laminar air stream which reduces projectile instability and as a secondary benefit, reduces the report of the rifle. This kit is 100% compatible with the stock end cap or the DonnyFL A50 adapter.
Air Stripper comes with o-ring and silicone grease for installation. I strongly recommend that you watch my installation video below.
Replacement Air Stripper 0-ring is 14mm x 1.5mm

This can be added to a custom build order or a send-in modification request.

The barrel will be heavily cleaned and coated with silicone oil to protect the surfaces for the trip home.
Once the order is received, a follow-up email will be provided. Depending on the service request, the response will contain detailed shipping instructions, including the shipping address and other pertinent information required on the label for the service request being shipped to us.
This service price does not include shipping or parts. Shipping costs to return your PCP or PCP parts will need to be calculated and communicated to you before the order ships back.
The reduction of an airgun barrel typically results in a decreased rate of travel of 15-20 ft/s per inch.
