Arca to Spartan 12mm Converter

I am happy with the quality of the adapter with only one issue. I use RRS tripods and mounting accessories. They use a locking pin to keep the attachment from walking forward or backward. I wish that the adapter had the locking hole machined into the bottom of the adapter to do the same. I will machine the holes, but it would have saved time to have them already in the adapter. But, the adapter is well made.

I have the Spartan Javelin Pro Tac bipod that is used across three rifles (two air and one ballistic) with either Spartan Classic or Gunsmith adaptors fitted in various positions (forward for bipod, or at the balance point - or as close as I can get to it) for tripod mounting. I also have a Manfrotto tripod for camera and telescope use, with their PL200 connector. Where I had been clamping my rifles into the tripod I now have the Spartan Converter in a Swiss Arca to PL200 adaptor - and I can now just put my rifle(s) onto the Arca to Spartan converter, and no clamps! All rifles just ‘sit there’ ; no movement at all, and lift off, traverse or remount in a second thanks to the Spartan magnet system. It makes standing, hands free, for - sometimes - hours waiting for the vermin (rats, rabbits, pigeons etc) to appear so much more comfortable. A brilliant and useful, inexpensive accessory!

Fits a treat onto my tripod, fitted like a glove

A nice way to get your rifle onto a tripod if you are bought into the spartan mag-lock system.

Pros: Flawless Machining: The build quality is top-notch. It features perfectly executed CNC machining with an excellent fit and finish.

Cons: Lack of Lockdown: The main drawback is its inability to lock the rifle securely into the ballhead of your tripod.

Excessive Movement: Instead of holding the rifle steady for precise shots, it allows the rifle to swing and move too freely. This actually creates more movement than if you were shooting freehand.

Verdict: While beautifully made, it fails at the most critical task of a tripod setup: keeping the rifle rock-steady. The inability to mechanically lock the system makes it frustrating for precision shooting and hunting at range.

Great product that fits my needs ! Product was ordered and received sooner than expected. Will definitely look at their other products !

Just what I was looking for!

This little mount holds a full-size rifle steady enough to walk away from and have it float - detaching is less than one second. Hardly notice the adapter on the front sling mount, too!

Best products from a great company! Love how you can retro adapt to other platforms such as arca etc

good adapter, fits solidly to tripod to allow rifle to mount easily. one improvement I would suggest would be to make it 4-way so it can mount quickly without having to turn it to the correct orientation.

Having the Arca to Spartan converter coming in really handy switching from binoculars to the rifle. I did spray paint it bright orange, taping off the post, so that if it's ever dropped in the grass I can find it.

Doesn’t have a tight positive fit like one would expect. But it’s okay

Does what it’s supposed to do and really appreciate you not price gouging on these small accessories like other brands. Keeps me coming back!

Wrks perfect

Works perfectly

Great addition to my collection of quick Attach

Makes any Arca Tripod work with other Spartan Products! Solid aluminum, great machining and fitment as always.

Solid tripod adapter for my rifle.

Makes it great to be able to use a tripod in the back country for glassing and shooting

As with everything Spartan Precision makes, its rock solid and well engineered. Works well on my tripod to accept my binos and rifle.

Purchased the converter for my Hatch bipod, which has an arca head on it for my XLR chassis stock. Now I can use it on my PROOF Elevation rifle as well!! A win - win situation!! It fit perfectly on the arca head and it’s super lightweight! Fit and function perfection!! Thank you Spartan!! Mike B.

I have used this for various things but is used most of the time for mounting my spotter on my tripod

Surprisingly solid for the size! Really impressed with the ease and functionality of this

I was turned on to Spartan in the Guidefitter app. I bought it to hunt with and have now purchased over $1,000 worth of gear from them and will not leave home without it! Keep up the good work!--Ted Lidie California Hunting Guide.

Bought this to have the ability to mount my gun to my tripod that is arca compatible. Now I can shoot off my bipod or tripod. Good quality. Pleased with my order.

Friendly and fast service

Great products Good service

Handy little widget that converts any arca setup to the speed and convenience of the Spartan system.

Very convenient to remove your spotting scope and use your tripod for a solid rest.

I really appreciate such a simple solution. This works perfect on my current tripod setup.

Packing a tripod for a spotting scope anyways so why not be able to use the tripod for more than glassing! Love the steadiness and ease of use! Great addition!

Great accessory to stabilize shots off a tripod. Simple and durable!

Works great!!
