Ruger American Gen II LOP Spacer Kit 90747

Customize Your Rifle's Fit

The Ruger American Rifle Generation II stock features adjustable length-of-pull spacers that let you fine-tune how the rifle feels at your shoulder. Getting the length-of-pull right is fundamental to accurate shooting—it ensures consistent shoulder placement and faster sight acquisition.

What's Included

Your Ruger American Gen II arrives with a 13.75" LOP spacer installed. This kit provides two additional spacer options:

• 12.75" LOP spacer for shooters who prefer a shorter pull
• 13.25" LOP spacer for intermediate adjustment

Easy Installation

Changing spacers takes just minutes with basic tools:

• 3/16" hex wrench
• 7/16" socket or wrench
• 1/8" hex wrench (for rear swivel stud, if needed)

Simply loosen the recoil pad assembly, swap in your preferred spacer, and tighten. Only one spacer can be installed at a time—they cannot be stacked.

Why Length-of-Pull Matters

Proper length-of-pull improves comfort during extended shooting sessions and enhances control. More importantly, it promotes consistent sight picture and faster target acquisition, directly supporting better accuracy. Whether you're shooting for sport, hunting, or precision work, getting this dimension right makes a measurable difference.
