Frequently Asked Questions

What components make up the custom Springfield Echelon "Space Blaster" build?

The custom Springfield Echelon build features a Mischief Machine full-size grip module, an Echelon Aimpoint Koa slide assembly, and a Harrington Arms compensator designed for full-size frames. A Surefire X300 weaponlight is also shown as an optional accessory.

How does the Mischief Machine grip module and Harrington Arms compensator affect the Springfield Echelon's shooting characteristics?

The added weight from the metal Mischief Machine grip and the Harrington Arms compensator significantly reduce felt recoil and muzzle flip, making the Echelon more stable and pleasant to shoot. This combination contributes to faster follow-up shots and improved overall shooting dynamics.

What are the accuracy results for the custom Springfield Echelon build?

During accuracy testing at 15 yards using Supervel Ultramat 9mm 124-grain ammunition, the custom Echelon achieved groups as tight as 3/4 of an inch, with three rounds nearly touching. This demonstrates excellent precision for the modified firearm.

What is the advantage of the Harrington Arms compensator on a full-size Echelon frame?

The Harrington Arms compensator is specifically designed to recess into the full-size Echelon frame, preventing interference with slide cycling. This unique design allows for effective recoil reduction without compromising the firearm's functionality, unlike other compensators tested.
