Why Upgrade to the EX Performance Kit
Complete Furniture Upgrade: Includes both the adjustable M4-style buttstock and ergonomic forend—a matched set that improves balance, control, and shoulder fit right out of the box.
Tough, Lightweight Build: Reinforced polymer construction shrugs off bumps, weather, and solvents while keeping weight in check for long training days.
Enhanced Recoil Management: The stock’s recoil pad and geometry help soften perceived kick, facilitate quicker follow-up shots, and maintain target focus.
Fast, Confident Grip: The forend features aggressive texturing and molded finger grooves for a secure, non-slip purchase with wet hands or gloves.
Adjustable Length of Pull: M4-style stock offers multiple positions to tailor LOP for body armor, seasonal layers, or different shooters.
Sling-Ready: Integrated QD/slot options (vary by production run) make it easy to configure single- or two-point sling setups.
Clean, Low-Glare Look: Matte black finish matches factory receivers and modern accessories for a professional aesthetic.
Ideal For
Home & Property Defense: Improved ergonomics and recoil control for confident manipulation in tight spaces.
Training & Classes: Durable furniture that stays comfortable and consistent across high round counts.
Hunting & Field Carry: Adjustable LOP for heavy jackets and pack straps; textured forend for sure cycling in rain or cold.
Overlanding & Ranch Use: A rugged, easy-to-maintain upgrade for rough environments.
Compatibility
Fits: Remington 870, 12-gauge (most standard 870 models)
Does Not Fit: 20-gauge, .410, or other non-12-gauge variants
Note: Some models/older 870s may have minor dimensional differences; verify your receiver/forend tube style and any included spacers before installation.
Installation (Quick Guide)
Unload & clear the shotgun; visually/physically verify the chamber and magazine are empty.
Remove factory stock: Loosen and remove the stock bolt inside the buttstock; retain hardware as needed.
Install M4-style stock: Attach the new stock per the included instructions; torque to spec.
Replace forend: Remove barrel and action bars; swap the factory forend using a forend nut wrench; reassemble action bars and barrel.
Function check: Confirm full, unobstructed pump travel and safe operation before live fire.
Pro Tip: If you plan to mount a weapon light, consider a low-profile clamp or a forend with a concealed Pic rail (sold separately) to keep your setup snag-free.
What You’ll Notice on the Range
Faster, cleaner cycling thanks to the forend’s traction and contour.
More consistent shoulder index with an adjustable LOP that fits your stance and gear.
