Why both a Spigot and Arca rail?

[Josh H]

Watching guys at the local PRS club match I can really see the value of an Arca rail. The question is why not just run a longer rail instead of both a rail and a Spigot.
Thank you

If you're referring to the MPA chassis, in my understanding the spigot mount is more meant for prone shooting. Placing the bipod further out helps with stability. The spigot mount also predates the full-length Arca rail in design. I believe you can order most MPA chassis with or without it these days.

Spigot also puts the bipod closer to the center of the bore, ideally making it more stable.

i ran a krg bravo with a arca rail and a spigot and i didn't like having to unhook the bipod off the arca then onto the spigot, but i have upgraded to a mdt acc and it has a long forend with arca built in and no spigot and it's a lot more convenient

The arca system allows you to easily shift items back and forth...like if i need my bipod legs closer to the mag for shooting off a table

I run an arca rail and a pic rail spigot on my AT. My reasoning is because I have seen and had arca rails slip. So, when I can, I always use the spigot mount.

I only use the arca rail on stages where I don’t have enough room or I will need to move the bipod during the stage.

The spigot to Araca transition is one of the main reasons I'm thinking about a long Arca instead of Spigot/Arca. I'm running the KRG B as well. Do you feel like the upgrade to the MDT ACC was a big improvement? Besides it having the full Arca... Thank you!

Yes. it was an improvement, i did like the bravo but for what i was doing i wanted something with more weight and that long forend on that ACC is awesome but it was a lot of money
