Description
Please be sure to measure your free area or clearance between the bottom of your scope to the top of the magazine well.
The HP Mini magazine height is 40.90MM (1.610″) compared to the much larger 50mm expanded mag
$33.00
The same reliable design as our expanded magazine but is slightly shorter to allow the magazine to fit under your optic without the need to adjust or swap out your scope rings.
The HP Mini magazine is designed to fit the Benjamin Marauder in .22 and .25 calibers. This magazine extends your capabilities by increasing the number of shots between reloads. The magazine’s operation is smoother and offers a more reliable chambering of rounds.
WILL NOT FIT THE BENJAMIN MARAUDER PISTOL
The stands only 40.90mm (1.610″ a little less than 5/8″)
The NO LID design means you simply rotate the projectile carousel and drop in each round. There is no need to preload the spring, you are winding the spring during the loading process. This fits under high-scope rings and some medium-scope rings. Your scope may need to be moved forward or back to clear the turret bell, maybe

Eaglevision INS Mount
Eaglevision has designed and developed an amazing scope mount that allows the scope to move vertically along a guided path. The mount is lockable in different positions using two screws. This mount can be used as a low profile or be adjusted to the high profile too if your scope objective is too close to your rifle barrel or shroud. These mounts resolve a lot of problems for shooters who like to shoot long range and often run out of adjustment clicks on their turrets.
The mount can also come in handy if you have not been able to use your favorite scope due to lack of space between the rings or the odd position of your dovetail or Picatinny rail on your gun. We are very proud of this product as it became a “must-have” for people who love their bullpups.
The best application of this mount however is for people who want to reach out further than their ordinary mounts allow them to. By keeping the front mount at its lowest and elevating the rear mount to the highest point you can zero in your gun far beyond your normal mounts allows you to, without using the clicks on your turrets hence keeping the optical center of your scope intact (the ideal situation for long-range shooting).
Another great feature is these mounts allow the scope to be lifted to allow for large or expanded magazines.
Item includes:
Tube/Rail Option: 30mm/Picatinny
Tube/Rail Option: 30mm/Dovetail
Air Stripper, Tension Spring and Baffle Stack
UPDATE: The newer avengers 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 Avenger
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. The installation video for the Umarex Origin Strip Stak Pak is exactly the same so you can follow the installation video below.
Replacement Air Stripper 0-ring is 14mm x 1.5mm

Hajimoto Productions Tuning O-ring kit for the Gauntlet and Gauntlet 2
Now includes two of my “NO RING” pellet probe seals as HP-1 rather than the typical high wear donut orings.
I have put together the most common o-rings that fail during a tuning session. Most of the stock o-rings for the internals will gouge when the airgun is disassembled, this kit will allow you multiple attempts should any of the o-rings fail. Please note that the .30 caliber uses completely different internal o-rings than all previous Gauntlet Models including the .30 cal exclusive transfer port orings Which will be bagged as TP.
Some of the NO-Ring seals have the leading edge precision ground.

These tapered / precision ground types need to be installed as shown below
(Images are of the .30 caliber NO RING)
You get:
Fits the Nova Liberty, Aspen, AV Avenger, and Origin PCP’s
This is a direct replacement end cap that when installed provides 1/2 x 20 UNF threads to allow the installation of your favorite moderator or suppressor. If you are looking for a better and stiffer barrel to barrel shroud connection that helps eliminate point-of-impact changes or projectile clipping issues, consider going with the A70 Adapter which essentially marries the barrel to the shroud.
If you are a Hajimoto Productions Strip Stak Pak (SSP) user, then stick with the A50 because the A70 will not work with the SSP.
