A rifle marked “AK” tells you very little about furniture fitment. Rear trunnion geometry, receiver pattern, stock interface, and handguard dimensions decide whether a stock or handguard installs cleanly or turns into a fitting problem.
AK furniture compatibility is not a single fitment standard. A rifle labeled “AK” may share caliber and appearance with another model while using a different furniture interface.
The term “AK furniture” often covers rifles with different rear trunnions, stock tang arrangements, receiver patterns, and handguard dimensions across AKM, Yugo-pattern, WASR-10, PSA AK, AK-100-style, and other commercial variants.
Why “AK Furniture” Is Not One Standard
Unlike platforms with more standardized rear stock interfaces, AK-pattern rifles can vary by receiver pattern, rear trunnion, stock interface, and handguard dimensions.
That difference is why compatibility must be confirmed before ordering furniture.
WOOX compatibility guidance lists most stamped receiver AK-47 / AKM / AK-74 pattern rifles with fixed stocks and single tang trunnions as compatible, while excluding milled-receiver rifles and Yugo pattern AKs.
Before ordering furniture, confirm:
- Receiver pattern: AKM, Yugo/Serbian, milled, AK-100-style, or another commercial pattern
- Rear trunnion type
- Stock mounting interface
- Handguard dimensions
- Fixed-stock vs folding-stock configuration
- Manufacturer-stated compatibility
Skipping those steps creates most fitment problems.
Buyers uncertain about receiver geometry or stock interface should confirm the current WOOX product page and fitment guidance before purchasing furniture.
AKM: The Pattern Many Furniture Products Are Built Around
When some manufacturers use phrases like “standard AK,” they often mean stamped AKM-style fixed-stock geometry, but the product page should still define the exact receiver and trunnion requirements.
Stamped AKM-style receiver geometry commonly serves as a compatibility baseline for many aftermarket furniture products.
That does not make every AKM-labeled rifle or AK-style rifle automatically compatible.
In practical terms, a common fixed-stock AKM-style configuration typically includes:
- A stamped receiver
- A fixed rear trunnion with single tang
- Standard AKM-style stock attachment geometry
- Matching AKM-pattern handguard dimensions
That distinction matters because not every rifle labeled “AK” follows the same receiver geometry.
WOOX’s FORTY SEVEN platform is intended for most stamped receiver AK-47 / AKM / AK-74 pattern rifles with a fixed stock and single tang trunnion.
WOOX also notes that receiver tolerances can vary by manufacturer and some fitting may be required.
Why Yugo Furniture Often Does Not Fit AKM Rifles
Yugo-pattern rifles create one of the most common AK furniture fitment mistakes.
Zastava/Yugo-pattern M70 rifles use furniture interfaces that differ from standard AKM geometry, which is why manufacturers often separate products into “AKM” and “Yugo/M70” compatibility categories.
An AKM stock or handguard should not be assumed to fit a Yugo-pattern rifle, even when both rifles chamber the same cartridge.
WOOX compatibility guidance excludes Yugo pattern AKs from its standard AKM furniture compatibility.
That distinction matters when evaluating aftermarket furniture.
If a product page says “AKM compatible,” that does not automatically mean Zastava M70 compatible.
The safer question is not:
“Is this an AK?”
The safer question is:
“Is this exact rifle an AKM-pattern fixed-stock rifle, a Yugo/M70 pattern rifle, or something else?”
WASR-10: Usually Closer to AKM-Pattern Fitment
The WASR-10 is often a more straightforward AKM-style furniture check than a Yugo-pattern rifle because many WASR-10 configurations are commonly associated with Romanian AKM-pattern geometry.
Manufactured at Romania’s Cugir Arsenal, the WASR-10 is widely regarded as a Romanian AKM-pattern rifle.
That generally makes standard AKM-style furniture compatibility more likely than with Yugo-pattern rifles.
As import configurations, prior modifications, and installed furniture can vary, confirm rear stock geometry before assuming compatibility.
The correct question is not:
“Will this fit a WASR?”
It is:
“Does this WASR use the rear trunnion, stock interface, and handguard dimensions required by this product page?”
Those are not always the same question.
PSA AK: The Name Alone Is Not Enough
PSA AK is a product family, not a single rifle pattern.
Palmetto State Armory produces multiple PSA AK variants, so furniture compatibility should be confirmed on the exact PSA product page before ordering.
Do not assume one PSA AK furniture interface applies to every PSA AK model.
Furniture compatibility depends on the exact PSA AK model, rear trunnion, receiver pattern, and stock interface, not the platform label alone.
If the product page or manufacturer specification does not explicitly confirm compatibility with AKM-style fixed-stock furniture, do not assume it.
Buying for the platform family instead of the exact receiver pattern creates avoidable fitment problems.
Five Things To Confirm Before Buying AK Furniture
Before ordering any stock or handguard, confirm five details.
Receiver Pattern
Identify whether the rifle follows AKM, Yugo/Serbian M70, AK-100-style, milled receiver, or another commercial receiver pattern.
This is the first compatibility filter.
Rear Trunnion Type
Rear trunnion geometry determines stock mounting compatibility.
Fixed single-tang systems, underfolders, side-folders, M1913 rear rails, and proprietary interfaces require different furniture.
WOOX compatibility guidance lists most stamped receiver AK-47 / AKM / AK-74 pattern rifles with fixed stocks and single tang trunnions as compatible for its standard AK furniture.
Milled receivers and Yugo pattern AKs are excluded from that standard fitment.
Fixed vs Folding Stock Interface
A rifle designed around a folding stock may require a different mounting solution than a fixed-stock AKM rifle.
Do not assume cross-compatibility.
For WOOX’s FORTY SEVEN Edge Kit, WOOX lists compatibility with rifles equipped with an M1913 rail from the factory or fitted with an aftermarket M1913 adapter.
Confirm the selected WOOX product page before ordering.
Handguard Dimensions
Yugo-pattern rifles commonly use handguard dimensions distinct from standard AKM geometry, preventing many AKM handguards from installing correctly.
Handguard fit should be verified by exact product page, receiver pattern, and manufacturer guidance.
Manufacturer-Stated Compatibility
If the manufacturer lists supported rifles, trust that list over assumptions.
Compatibility language such as “stamped AKM receivers,” “fixed stock and single tang trunnion,” or “not compatible with Yugo pattern AKs” exists for a reason.
Where WOOX Fits Into AK Compatibility
The WOOX FORTY SEVEN platform is built around verified AK receiver and rear-interface geometry rather than the broad “AK” label.
WOOX compatibility guidance specifies that the FORTY SEVEN platform is intended for most stamped receiver AK-47 / AKM / AK-74 pattern rifles with a fixed stock and single tang trunnion.
WOOX also excludes milled-receiver rifles and Yugo pattern AKs from that standard compatibility group.
For WOOX’s FORTY SEVEN Edge Kit, WOOX lists compatibility with rifles equipped with an M1913 rail from the factory or fitted with an aftermarket M1913 adapter.
Confirm the selected WOOX product page before ordering.
WOOX notes that receiver tolerances can vary by manufacturer and may require fitting.
That distinction matters because many fitment problems begin with the same mistake: buying for the AK family rather than the specific AK pattern.
A rifle marked “AK” tells you very little about furniture compatibility.
Receiver pattern, rear trunnion geometry, and stock interface tell you far more.
Frequently Asked Questions
Will AKM furniture fit a Yugo M70?
Generally, no. Many Yugo/Serbian-pattern rifles use furniture dimensions different from standard AKM geometry, which is why manufacturers separate “AKM” and “Yugo/M70” compatibility. WOOX excludes Yugo pattern AKs from its standard AKM furniture compatibility. Confirm fitment before ordering.
Is the WASR-10 an AKM-pattern rifle?
In most cases, the WASR-10 is commonly treated as a Romanian AKM-pattern rifle, making standard AKM-style furniture compatibility more likely than with Yugo-pattern rifles. Still, verify the exact rear trunnion configuration, stock interface, and product-page compatibility before ordering parts.
Do all PSA AK rifles use the same furniture?
No. Palmetto State Armory produces multiple PSA AK variants, and furniture compatibility depends on the specific rifle model. Manufacturer-listed compatibility should always be confirmed before purchasing aftermarket furniture.
Why do AK parts not always fit?
AK-pattern rifles are produced across multiple manufacturing patterns, which can create differences in receiver geometry, rear trunnions, stock interfaces, and handguard dimensions. Those differences affect furniture compatibility.
What should I check before buying WOOX AK furniture?
Check whether the rifle is a stamped AK-47 / AKM / AK-74 pattern rifle, whether it uses a fixed stock and single tang trunnion, whether it has a milled receiver or Yugo pattern, and whether the selected WOOX product page lists your configuration as compatible. For M1913-style setups, confirm whether the rifle has a factory M1913 rail or a compatible aftermarket M1913 adapter.
