Repeating fire on a budget is the whole pitch of the EK Archery Adder, and after my two-week pistol crossbow protocol I can say the 5-shot magazine delivers on it. At $389–$415 it earns 4.2 out of 5 from me as a repeating, AR-style crossbow for target shooting and casual use, not as a big-game hunting tool.

The Adder is a pistol-grip, AR-style repeating crossbow with a 130 lb Cobra System recurve limb and a rating of 270 FPS. It ships with a red dot sight, front grip, adjustable stock, carry sling and 15 carbon bolts. My protocol covered magazine feed cycling, chronograph verification and cocking effort.

This review answers the questions buyers type most: how much it costs, how fast it is, whether the magazine jams, what comes in the box, and how it compares with the cheaper Steambow and SAS repeaters.

What I Like

The magazine and the bundle are the two reasons to look at the Adder, and I tested both.

  • A magazine that cycles reliably. The 5-shot magazine dropped a fresh bolt into the chamber after each trigger pull, and I fired a full magazine noticeably faster than any single-shot crossbow in my lineup.
  • Manageable cocking effort. At 130 lbs of draw weight, the Cobra System recurve limb cocked with less effort than full-size compound platforms in my testing.
  • A complete package. The red dot sight, front grip, adjustable stock, carry sling and 15 carbon bolts meant I had everything needed straight out of the box.
  • A stock that fits different shooters. The adjustable stock let shooters of different builds find a comfortable, stable position without an aftermarket accessory.
  • Repeating fire at a fair price. At $389–$415, it offers a repeating mechanism and a full accessory kit well below dedicated hunting-tier repeating platforms.

So far in testingIf a 5-shot magazine and a ready-to-shoot kit with 15 bolts is your priority, check the current price.

Potential Drawbacks

None of these is a deal-breaker for the right buyer, but each changes who should choose the Adder.

  • Not for big game. Rated at 270 FPS, it sits below full-size compound hunting crossbows, as my chronograph testing confirmed. It suits target shooting, small game and casual use.
  • A basic optic. The included red dot was serviceable, but precision aiming at extended distances was limited without upgrading it.
  • Reloading interrupts the pace. Refilling the magazine between 5-shot cycles takes a deliberate step, which I found slower than topping off a single-shot crossbow between sessions.
  • A stance that will not suit everyone. The pistol-grip, AR-style stock may not match the preferences of hunters used to a traditional rifle-style crossbow stock.

Key Features Explained

How does the 5-shot magazine work?

Most crossbows, including every single-shot pistol crossbow in my lineup, need a new bolt placed on the rail after each shot. The Adder's auto-loading magazine automates that step, and it dropped each successive bolt into position without manual intervention. That matters to anyone who wants faster shot-to-shot cycling than a traditional design allows. Remember that each shot still needs the string cocked by hand.

Watching the magazine feed shows why repeated shots come faster than on a single-shot crossbow.

How hard is it to cock at 130 lbs?

The Cobra System recurve limb cocked with manageable effort, noticeably easier than the higher-draw-weight compound platforms in my broader lineup. It still takes physical effort compared with a compound crossbow fitted with a cocking aid or a crank, and the cocking effort estimator will show what a 130 lb hand-cock means for your build. For help matching draw weight to your build, read crossbow draw weight by body size.

What comes in the box?

The bundled red dot, front grip, adjustable stock, sling and bolts gave me a complete setup with no extra purchases. The red dot was basic but functional, adequate for the closer-range shooting this platform suits best.

Does the adjustable stock help?

The stock let shooters of different heights and builds find a stable cheek weld and shoulder position. That is an advantage over fixed-stock pistol crossbows, which force a one-size-fits-all fit.


Performance & Usability

How accurate and fast is it?

Downrange grouping with the included red dot was solid at closer ranges, but precision fell off at extended distances without an optic upgrade. My chronograph confirmed the 270 FPS rating. The magazine feed is the Adder's core selling point, and it cycled reliably across repeated firing sessions without significant jamming.

Is it comfortable to shoot?

The adjustable stock and front grip gave a stable, comfortable shooting position across sessions with shooters of different builds. At 7.9 lbs it is heavier than other pistol crossbows in my lineup, so expect it to feel more like a small rifle than a handheld.

Is the cocking routine consistent?

Cocking the Cobra System limb repeatedly felt consistent from session to session, with noticeable but manageable effort at 130 lbs.

Who Is the Adder For?

The Adder suits shooters who value cadence and a complete kit over raw power.

Best suited to:

  • Shooters who want repeating fire with a higher speed ceiling than budget alternatives
  • Buyers who value a complete package of optic, grip, stock, sling and bolts without piecing it together
  • Target shooters, small-game hunters and prepper-minded buyers who prioritize rapid-fire capability

Consider something else if:

  • You need hunting-capable speed for big game
  • You prefer a traditional rifle-style stock

EK Archery Adder vs Alternatives

Two cheaper repeaters are the natural comparison, and the figures below come from their own review files.

Barnett Demun Accu Strike$145–$165190 FPS60 lbs~2 lbsCheck price on Amazon

The Stinger II offers a lighter, easier-to-cock 55 lb draw weight and a six-arrow magazine at a lower price, and the Prophecy 80 is a budget plinking option. The Adder beats both on chronographed speed and ships with a ready-to-go red dot rather than a basic sight. If you do not need a magazine, the Ballista Bat is a single-shot compound pistol crossbow that is faster at a measured 293–304 FPS and cheaper at $299–$399.

What Is in the Box and What Else You Need

My notes list a red dot sight, front grip, adjustable stock, carry sling, rail lube, string stopper and 15 carbon bolts, and the 5-shot magazine is part of the design. Fifteen bolts is three full magazines, which is a useful way to think about a range session before you need to reload anything.

ItemIncluded?Practical note
Red dot sightYesBasic; limits precision at extended distance
Front grip and adjustable stockYesLets different builds find a stable position
SlingYesHelpful at 7.9 lbs
15 carbon boltsYesThree magazines of 5
Rail lube and string stopperYesUse as the manual directs
Optic upgradeNot includedThe main upgrade I would consider
Spare boltsNot listedWorth having for longer sessions
Targets and backstopNot listedNeeded for any range use

The realistic extras are spare bolts, a safe target and backstop, and possibly a better optic. I do not quote prices for these because my notes give none.

Setup and First Session

Plan the first session around the magazine and the optic.

  1. Read the manual for loading the magazine and cocking the Cobra System limb.
  2. Adjust the stock to your build before aiming, since a stable cheek weld matters more than any accessory.
  3. Zero the red dot at close range first, the distance where it performed best in my testing.
  4. Load one magazine and fire it in a controlled string, noting whether each bolt feeds as expected.
  5. Remember that each shot still needs the string cocked by hand, so the pace is set by you.

Ownership and Care

My notes do not record a warranty term or service interval, so confirm both with EK Archery. General care for a recurve repeater follows the usual pattern:

  • Keep the rail lubricated as the manual directs; the kit includes rail lube.
  • Inspect the string and limb for wear and have a technician check anything unusual, as covered in how to maintain a crossbow.
  • Store it uncocked and unloaded, with the magazine emptied.

Worked Example: Adder vs the Stinger II

Using the review files, the Adder costs $389–$415 and the Steambow AR-6 Stinger II costs $145–$165. The low-end gap is $244 ($389 minus $145). The Adder's chronographed 270 FPS is 90 FPS above the Stinger II's 180 FPS (270 minus 180). The Adder's draw weight is 130 lbs against 55 lbs, which is 75 lbs more and roughly 2.4 times as much. It also weighs 7.9 lbs against 2.56 lbs, a difference of about 5.3 lbs. So the extra money buys speed and a complete kit, and the price is paid in cocking effort and carried weight.

Who Should Skip the Adder

  • Anyone who wants a light, handheld pistol crossbow, since 7.9 lbs behaves like a small rifle.
  • Buyers who need big-game speed, since 270 FPS sits below full-size compounds.
  • Shooters who want a precise long-range optic without upgrading the red dot.
  • Anyone who prefers a traditional rifle-style stock.

Value for Money

At $389–$415, the Adder costs more than the Steambow AR-6 Stinger II ($145–$165) and the SAS Prophecy 80 ($95–$115). The Stinger II offers a lighter, easier-to-cock 55 lb draw weight at a lower price, and the Prophecy 80 is a budget plinking option. The Adder beats both on chronographed speed and ships with a ready-to-go red dot rather than a basic sight.

The premium held up in my testing: the magazine cycled reliably, the accessory bundle was complete and the 130 lb draw weight cocked with manageable effort. For buyers drawn to the repeating mechanism rather than maximum hunting performance, it is a reasonable middle ground between ultra-budget plinkers and full-size hunting compounds.


At its rated 270 FPS, the kinetic energy calculator shows what the EK Archery Adder delivers with the bolt weight you plan to shoot, and the bolt drop chart estimates how far each reticle mark falls at that speed. The cocking effort estimator compares its 130-lb draw weight by hand, rope and crank. If you plan to replace the scope, the scope speed matcher lists reviewed scopes calibrated for 270 FPS. Every other model I have tested in this class is compared on the pistol crossbows page.

Final Verdict

EK Archery Adder

4.2 / 5 — Is it worth buying?

The EK Archery Adder delivers reliable repeating fire and a complete accessory package at a price well below dedicated hunting-tier repeating platforms. Its 5-shot magazine cycled consistently in my testing, and the included red dot, grip, stock and bolts meant no extra purchases. The trade-off is a speed ceiling below hunting-capable compounds, at 270 FPS, and a basic optic.

Frequently Asked Questions

  1. Is the EK Archery Adder worth it?

    Yes, for shooters who want repeating fire and a complete accessory bundle. The 5-shot magazine cycled reliably in my testing, and the optic, grip, stock, sling and bolts all came in the box. Buyers wanting big-game performance should look at full-size compound crossbows.

  2. Can the EK Archery Adder be used for hunting?

    It is better suited to target shooting and small game than big-game hunting. At 270 FPS, it trails flagship compound crossbows in speed and kinetic energy; the kinetic energy calculator shows the figure for your bolt weight. Check local regulations before using any crossbow for hunting.

  3. How does the 5-shot magazine work?

    It is an auto-loading system that drops a fresh bolt into the firing position after each trigger pull. It cycled reliably across repeated firing sessions without significant jamming, though the string still needs to be cocked for each shot.

  4. Does the Adder include everything needed to start shooting?

    Yes. It ships with a red dot sight, front grip, adjustable stock, carry sling, rail lube, string stopper and 15 carbon bolts.

  5. How does the Adder compare to the Steambow AR-6 Stinger II?

    The Stinger II has a lighter 55 lb draw weight and a lower price. The Adder is faster (270 FPS against 180-220 FPS for the Stinger II) and includes a more complete accessory bundle at a higher price.

  6. How heavy is the EK Archery Adder?

    It weighs 7.9 lbs. That is noticeably more than compact handheld repeaters such as the Stinger II at 2.56 lbs, so it behaves more like a short rifle than a pistol in the hand.

  7. How many bolts come with the EK Archery Adder and how many magazines is that?

    The kit lists 15 carbon bolts, which is three full 5-shot magazines. That is enough for a short session, but you may want spare bolts if you plan to shoot longer.

  8. Is the EK Archery Adder harder to cock than the Steambow Stinger II?

    Yes. The Adder has a 130 lb draw weight against the Stinger II's 55 lbs. I found the Adder's effort manageable but noticeable, so follow the manual and practise the cocking motion.

  9. Does the EK Archery Adder come with a scope or a red dot?

    It ships with a red dot sight, which was serviceable in my testing but limited precision at extended distances. Buyers who want finer aiming at range should plan on upgrading the optic.

  10. Does the Adder fire automatically after one cocking?

    No. The magazine feeds a fresh bolt after each trigger pull, but the string still has to be cocked by hand for every shot, so it is a repeater and not an automatic.
