Kraken SRS Hop-up Chamber Ultimate Edition - V2
(Also compatible with Silverback HTI)

The Kraken SRS hop-up chamber from Stalker evolves and turns your SRS into a beast! Stalker offers a unique modular design that eliminates all previous sealing and alignment issues. Comes with Stalker’s exclusive 2-fin VSR-style bucking and its quick-setup design makes it a powerful upgrade for the SRS hop-up chamber. After years of perfect performance with the V1 and over 22 five-star reviews, it was time to create the V2 and improve it further. Key V2 upgrades include a smaller front head to reduce bolt friction, a stainless steel body that’s nearly indestructible even under tight hop-up pressure, and other refined improvements.

Features:

  • Easy setup for professional and new players (~2 minutes to change bucking)
  • 100% self-aligning system for perfectly straight bucking/nub
  • Patented Kraken bucking: 100% straight / 100% sealed
  • Adjustment wheel with head cutout for easy tuning
  • O-ring guided wheel
  • Custom stainless steel hop-up arm screw
  • Laser-engraved letters and text
  • Front O-ring to prevent BBs from falling into the receiver
  • Modular chamber design compatible with most VSR buckings, bridged/unbridged barrels, and nubs
  • Modular arm section to swap and use S1, S2, and S3 arms
  • High-quality stainless steel hop-up body
  • V-shaped island for upper outer barrel screw (SRS A1)
  • V-shaped island for lower outer barrel screw (SRS A2)
  • Quick setup for barrel or bucking changes or barrel cleaning

This ULTIMATE package includes:

  • 1x Kraken SRS VSR-style hop-up chamber head
  • 1x Kraken SRS stainless steel hop-up chamber body (indestructible)
  • 1x Kraken SRS hop-up chamber wheel
  • 1x Kraken SRS S1 hop-up arm (with Tigra nub attached)
  • 1x Kraken SRS S2 hop-up arm (with Prowler nub attached)
  • 1x Kraken SRS S3 hop-up arm (for nub)
  • 1x Kraken SRS hop-up arm spring
  • 1x Custom Kraken SRS hop-up arm screw
  • 1x Kraken SRS 60° concave 2-fin bucking
  • 1x Kraken SRS Prowler CNC aluminum nub (Purple for S3 arm)
  • 1x Kraken SRS Tigra CNC aluminum nub (Orange for S3 arm)
  • 1x Kraken SRS hop-up chamber head O-ring
  • 1x Kraken SRS hop-up wheel O-ring
  • 1x Kraken SRS rear chamber body O-ring
  • 3x Kraken SRS chamber body locking screws
  • 2x Kraken SRS inner barrel locking screws

NOTE:
This chamber provides 100% sealing with the Stalker bucking included in this package. It also works with other VSR-style buckings, but for perfect 100% sealing, Kraken buckings from Stalker are strongly recommended, as standard VSR buckings have a wider inlet and the standard SBA nozzle may not seal them fully.

NOTE:
Keep in mind that SRS A1 Sport or Carbon outer barrels may require an additional washer behind the hop-up body for proper function.

Like the best military items: does exactly what it's used for:
Color: Black
Even better than the infantry watch I used in the USAF 50 years ago. It has 12/24 hour time and day/date; other models have additional features. It's rugged and easy to read - a real watch face, NOT digital ! ... AND inexpensive too. BTW it has a real watch band made to be used in the elements (e.g. weather, work).

Infantry 5ATM Waterproof Mens Military Tactical Field Watch, Date & Day 12/24Hr-
Color: Silver
So I almost never write reviews- anywhere. This is an exception & I'm not paid or reimbursed- just impressed. This watch presents a really good price to value ratio. My infantry watch looks great and is very functional. I put a NATO strap on it because I tend to be tough with watches, though the one it arrived with is very nice looking and the buckle is even logo'd- a really nice touch in this price segment. I've received several positive compliments while wearing it and 1 of my friends has purchased an Infantry field watch from this same series since. The company behind the watch is part of the value equation. I had a minor issue and I was able to get in touch with a real person... no, actually two! I contacted via Amazon AND through the support dept from their website. Both inquiries were promptly answered with a helpful and well-mannered reply and the perfect solution. There are several collections to be found on their website (SEARCH: Infantry Watches ). These watches range in appointment and quality from levels found here to several steps above. Similar in looks and nature to this one on Amazon include; The Chronomaster, The Skeleton, and The Auto-Pilot to name a few. I've begun to add additional watches to my collection from those. There are also fun and informal collaborations offered. Right now [8-2025] these include; Transformers, Monopoly, Peanuts and several others. ---> Overall it's rare and refreshing to find a company still able to work decent products AND ethics into a successful business model!

Simple, affordable, smartly styled. Good starter watch for teens
Color: Black
Got this for 13-year-old boy for Christmas. Excellent choice for a beginner's watch. Learn to read a clock face for crying out loud! Easy to set the day/date, and has a comfortable band.

Style classic
Color: Silver
A neat watch, I was a career soldier and I remember getting a few different military style watches, mostly made by Timex. I was in supply so had access to them, often the style was the same and sometimes not. Item was packed well and arrived fast great price
