A 1/2-inch buttstock spacer can add length behind a stock and help adjust length of pull, but the right choice depends on the firearm’s stock style and the spacer’s listed dimensions. The KICK-EEZ options below are oversized, grind-to-fit spacers for shotgun or rifle stocks; the Eastern Tactical Supply option is specifically for standard A2 buttstocks. Product details provided here do not confirm the thickness of each KICK-EEZ listing, so check the selected size before ordering.
| Product | Best For | Fit Type |
|---|---|---|
| KICK-EEZ, listing A | Custom shotgun or rifle fit | Oversized; grind to fit |
| KICK-EEZ, listing B | Adjustable stock length | Oversized; grind to fit |
| Eastern Tactical Supply A2 set | Standard A2 buttstocks | A2-specific spacer and screw |
| KICK-EEZ, listing C | Custom fit and finish | Oversized; grind to fit |
| KICK-EEZ, listing D | Fine-tuning stock fit | Oversized; grind to fit |
KICK-EEZ Universal Stock Spacer, Listing A

Best for: A shotgun or rifle owner who wants to customize stock length and is comfortable shaping a spacer for a close fit. The listing describes a lightweight plastic polymer spacer intended to sit between the buttstock and recoil pad.
Its oversized, grind-to-fit design can accommodate a range of stock outlines, and the material is described as suitable for machining and sanding. The spacer is intended to increase length of pull and help adjust shoulder placement. It was selected because its stated purpose directly matches stock-fit adjustment.
Limitation: The supplied product details do not state that this specific listing is 1/2 inch thick. Confirm the chosen thickness and required finishing work before purchase.
KICK-EEZ Universal Stock Spacer, Listing B

Best for: Shooters who need an adaptable spacer for a shotgun or rifle and want to finish its edges to match the stock. The listed polymer construction is lightweight and designed for sanding or machining.
This option adds material at the rear of the stock to increase length of pull. It is described as oversized, making it a better fit for buyers who can trim and finish the spacer rather than those seeking a ready-shaped, exact-fit part. Its broad firearm description makes it a relevant choice for custom stock work.
Limitation: The listing details provided do not specify its thickness. Do not assume it is a half-inch spacer without confirming the selected variant.
Eastern Tactical Supply A2 Spacer Set

Best for: Owners of a standard A2 buttstock who need the spacer-and-screw set described in the listing. It includes an A2 buttstock spacer and a 1.2-inch screw with a gas port, and the product information states that it is for all standard A2 buttstocks.
Unlike the KICK-EEZ options, this is an A2-specific set with a machined, high-strength steel construction. It was selected for buyers searching for a buttstock spacer who need the listed A2 configuration rather than a universal grind-to-fit part.
Limitation: The provided details do not state that the spacer itself is 1/2 inch thick. It is not described as a universal shotgun or rifle spacer; check stock type and dimensions before buying.
KICK-EEZ Universal Stock Spacer, Listing C

Best for: Buyers who want a customizable spacer to fine-tune length of pull on a shotgun or rifle. The stated purpose is to add thickness behind the stock, with the spacer installed between the stock and recoil pad.
The lightweight polymer is described as workable with machining and sanding, so it suits stock owners who can shape an oversized part to their stock’s outline. The listing also notes that the product is available in different thicknesses and colors, which may help buyers compare fit and appearance.
Limitation: The information provided does not identify the thickness for this specific URL. Verify that the selected option is 1/2 inch if that exact measurement is required.
KICK-EEZ Universal Stock Spacer, Listing D

Best for: A shotgun or rifle owner who needs a spacer that can be shaped to a particular stock rather than a pre-fitted model. Like the other KICK-EEZ options, it is described as oversized and intended for grinding or sanding.
It was selected because its stated function is to extend length of pull and customize stock fit. The spacer is designed to sit between the buttstock and recoil pad, allowing the user to adjust the rear stock dimension and finish the outline.
Limitation: The supplied listing details do not verify a 1/2-inch thickness or identify a specific firearm model. Confirm both the dimension and fit requirements before ordering.
Buying Guide: How To Choose A Buttstock Spacer
Is the spacer actually 1/2 inch thick?
Check the selected product variation and its listed measurements. The product information available for these options describes adjustable thickness choices for KICK-EEZ, but does not confirm which individual listing is the half-inch size. Do not rely on the product title alone when an exact thickness is essential.
Does it match the stock style?
Choose an A2-specific part for a standard A2 buttstock if the listed configuration matches your firearm. Choose a grind-to-fit spacer when you need a customizable outline for a shotgun or rifle stock. “Universal” does not mean every spacer fits every stock without modification.
Are you prepared to shape the spacer?
The KICK-EEZ options are intentionally oversized and designed to be ground, sanded, or machined. That can help create a close outline, but requires careful fitting. If you need a part that is already shaped for a particular stock, verify dimensions and installation details before purchasing.
What does a spacer change?
A spacer adds thickness at the rear of the stock and can increase length of pull. Measure the current setup and decide how much additional length is needed. Follow the firearm maker’s instructions for safe installation, and check that the spacer and fasteners are appropriate for the stock.
Frequently Asked Questions
What is a 1/2-inch buttstock spacer used for?
It adds approximately half an inch at the rear of a compatible stock to increase length of pull. Confirm the spacer’s stated measurement and fit before installation.
Can a grind-to-fit spacer work on any stock?
Not automatically. An oversized spacer can be shaped for many stock outlines, but the product must still suit the stock’s dimensions and attachment method.
Are all the listed KICK-EEZ options confirmed as half-inch spacers?
No. The supplied details describe thickness choices but do not confirm the thickness for each specific listing. Check the selected option before ordering.
Is the A2 spacer set interchangeable with universal spacers?
The A2 set is described for standard A2 buttstocks. It should not be treated as interchangeable with a universal grind-to-fit spacer without verifying dimensions and fit.
