Frequently Asked Questions

Mil-spec vs. commercial — which stock do I need?

The difference is the buffer-tube diameter the stock slides onto. A mil-spec tube is ~1.14" and a commercial tube is ~1.17" (and slightly angled at the rear). A stock must match its tube — a mil-spec stock won't fit snugly on a commercial tube and vice versa. Check which tube you have (or which the kit includes) before choosing a stock.

Fixed vs. adjustable stock?

A fixed stock is a single length (often A2 rifle length) — simple and rigid. An adjustable (collapsible) carbine stock slides on a carbine buffer tube to set length of pull, the most common modern choice. Match the stock type to your buffer-tube length (carbine vs. rifle).

What's included in a stock kit?

A stock kit typically includes the stock, the buffer tube (receiver extension), the buffer spring, the buffer, the castle nut, and the end plate — everything to complete the stock assembly on a stripped lower. Check the listing for the exact contents.

Will this fit my rifle or pistol?

Match the platform (AR-15 vs AR-10/.308 — they use different buffer systems) and the tube type (mil-spec vs commercial). Confirm both before ordering.
