Furniture — Wood to Synthetic

This is what most stock swaps actually look like, and the reason the handguard stays wood is in this volume.

Most of the SKSs I have owned have ended up in synthetics. The wood on a surplus rifle is usually the worst thing about it — split, oil-soaked, dented, sometimes three shades of refinish — and the SKS is one of very few military rifles where the barrelled action lifts straight out with no bedding, no action screws and no accuracy consequence to worry about. It is a fifteen-minute job with a punch and a screwdriver.

It is also the modification where the largest amount of wrong information circulates, starting with the biggest brand in the business.

13.1 Magpul Does Not Make an SKS Stock

Magpul makes nothing for the SKS. No stock, no chassis, no handguard, no magazine, no rail, no grip designed to fit it.

I went and checked their catalogue directly while writing this. Searching magpul.com for “SKS” returns, verbatim: “Your search returned no results.”

The reason this needs saying is what the page does next. Under that message the site offers five suggested searches:

“Sks polymer stocks kit”
“Sks polymer stock kit”
“SKS M4 Telescoping Pistol Grip Stock”
“sks moe stock”
“Sks fore grip and stock”

Those look exactly like a product list. They are not. They are query echoes generated from what people have typed into the search box, and every one of them leads nowhere. It is a genuinely easy thing to misread, and it is why “Magpul SKS stock” listings turn up on auction sites and marketplaces with some regularity — always mislabelled, usually a Tapco or an ATI, occasionally a generic import.

An independent 2026 upgrade guide puts it about as plainly as it can be put: “Magpul does not make an SKS stock or chassis. Any listing claiming otherwise is mislabeled.”

13.2 How Magpul Furniture Gets Onto an SKS Anyway

In every case the Magpul component fits a standard AR-pattern feature provided by a third-party chassis, and never touches the rifle. Source: original diagram.

Plenty of SKSs have Magpul parts on them, and there is nothing wrong with that. What is happening is one step removed:

A third-party chassis replaces the rifle’s stock and provides one or more standard interfaces. The Magpul part then bolts to the interface.

Table 1 — 13.2 How Magpul Furniture Gets Onto an SKS Anyway

Interface the chassis provides	Magpul parts it accepts
AR-15 grip screw and bushing	MOE, MOE-K2, K2+, MIAD grips
Mil-spec carbine buffer tube	MOE, CTR, STR, SL, ACS, ACS-L stocks
M-LOK slots	Rail sections, hand stops, bipod mounts, light mounts
Picatinny rail	MBUS and MBUS Pro back-up sights
QD socket or sling loop	MS1, MS3, MS4 slings

So the honest description of a “Magpul SKS” is: an SKS in a FAB Defense, ProMag, ATI or similar chassis, wearing Magpul furniture on the chassis’s AR interfaces.

That distinction matters practically as well as pedantically:

You are buying two things, not one. Chassis plus furniture, and the chassis is where the fit problems live.
Ergonomics come from the chassis, not from Magpul. How the rifle feels is decided by where the chassis puts the grip and the comb.
The parts count for the import-parts rule counts the pistol grip. Vol 17.

13.3 What Is Actually Made for This Rifle

The SKS aftermarket is not small. It is just not Magpul.

13.3.1 Drop-in replacement stocks

ATI Monte Carlo — around $81. A conventional sporter stock, no pistol grip, cheek comb raised for optics. “Installs with only slight modification for most people,” which in practice means occasional relief work around the trigger group or magazine. The lowest-drama way to get out of a broken military stock.

ATI Strikeforce / Strikeforce Gen2 — around $140. Six-position side-folding, Scorpion recoil pad, pistol grip. Fits most variants including the Yugoslav M59/66. The blade bayonet has to come off.

Tapco Intrafuse and T6 — roughly $65 to $79. The most common aftermarket SKS stock in existence, and the one most people picture. SAW-style pistol grip, bottom rail included. Sold in versions with and without a bayonet cut, which is the single most useful thing about the line. Two known annoyances: the sling mounts are not pre-drilled, and some parts combinations need adjustment.

ProMag Archangel and Archangel OPFOR — around $140. A full chassis with adjustable length of pull and an adjustable cheek riser. Drop-in on most variants. It adds weight, and on a rifle that already weighs 8.5 pounds that is a real consideration.

Figure 3 — The Tapco Intrafuse — the archetypal SKS synthetic stock, and the one most people mean when they say they re-stocked theirs.

Figure 4 — The ProMag Archangel OPFOR. Adjustable comb and length of pull, at the cost of weight.

Figure 5 — The ATI Strikeforce with its side-folding stock. Folding an SKS is a genuine gain in a truck or a pack; it costs you the bayonet.

13.3.2 Full chassis conversions

FAB Defense M4-SKS (FX-M4SKS) — around $324, and the most thorough of them. It replaces the whole stock with a chassis carrying an M4-pattern collapsible stock, a pistol grip and quad rails. It will not accommodate a bayonet in any configuration.

This is the category where Magpul parts enter, because the chassis provides the buffer tube and the grip screw.

Figure 6 — The FAB Defense M4-SKS chassis. This is the platform a "Magpul SKS" is actually built on.

Figure 7 — The same chassis on a rifle. Once the SKS is in one of these, everything on it is an AR accessory.

13.3.3 Bullpup conversions

A real and long-standing category on this rifle. Kits from SG Works and others move the action rearward in a shell that relocates the trigger, and most take a detachable magazine. They shorten the rifle substantially without shortening the barrel.

They are also the most invasive thing you can do to an SKS short of cutting it, and they add linkage between the trigger and the trigger group that is inevitably worse than the original.

Figure 8 — A bullpup conversion kit with the original wood stock beside it. Keep the wood.

Figure 9 — A cased bullpup kit, original stock included. That habit — every kit shipping with the factory furniture kept — is worth copying.

13.4 The Upper Handguard Problem

Look again at the photograph at the top of this volume. Buttstock and forend are polymer; the upper handguard is still wood.

That is not laziness. On most SKS stock kits the upper handguard is not part of the kit, because it is not part of the stock — it is part of the gas tube assembly (Vol 9 § 9.1, Vol 10 § 10.6). It clamps to the tube and it comes off with it.

Consequences:

A stock swap that does not include an upper handguard leaves you with wood on top and polymer below. Some people like the look. Most do not, and did not expect it.
Synthetic upper handguards exist and are sold separately, usually as a gas-tube-and-handguard assembly.
Do not fit an upper handguard that fouls the gas tube’s clearance. The tube gets hot and the handguard is what stops your hand knowing about it.

This is the number one surprise in an SKS re-stock and it is worth checking what a kit includes before ordering.

13.5 The Bayonet Decision

Before you buy a stock, decide what happens to the bayonet, because it determines what you can buy.

Keep it, folded — you need a stock with a bayonet cut. Tapco make theirs both ways for this reason.
Remove it — more stock choices open up, the rifle loses about half a pound off the muzzle, and it handles noticeably better. Removal is a real job (Vol 11 § 11.7).
Chassis conversions generally decide for you: the bayonet goes.

⚠ Keep the parts. A matching bayonet is worth real money on a Russian rifle and is part of what a collector is buying. Vol 13 § 13.8.

13.6 Doing the Swap

The whole job:

Field strip to the barrelled action (Vol 10, through step 9).
Remove any stock ferrule or band screw, and the sling swivels if they are separate.
Lift the action out of the wood.
Deal with the bayonet if the new stock requires it.
Drop the action into the new stock. Check for interference at the magazine, the trigger group hooks and the rear of the receiver before you force anything.
Reinstall the magazine and trigger group. The trigger group is where fit problems show up — if the latch will not click home, the stock is holding the group’s rear too high, and the answer is a little relief work, not a bigger hammer.
Reassemble the rest.
Function check (Vol 10 § 10.11), including the disconnector check.
Re-zero. You have changed how the rifle sits in your shoulder, and if the comb height changed you have changed your head position. Vol 16.

Total time on a rifle you have stripped before: about fifteen minutes, plus whatever the bayonet costs you.

13.7 What a Synthetic Stock Actually Gets You, Honestly

Real gains:

It does not care about weather. A wooden military stock moves with humidity. A polymer one does not.
Comb height for optics. This is the big one. The military stock’s comb was designed for iron sights and it is far too low for a scope; you end up with your cheek off the wood and no repeatable head position. Nearly every aftermarket stock raises the comb or lets you.
Length of pull. The military stock is short — designed for a conscript in a greatcoat. Adjustable stocks fix that.
You stop worrying about it. A $70 polymer stock in the truck is a different relationship than a matching-numbers 1954 Tula.

What it does not get you:

Accuracy. The SKS has no action screws and no bedding; the barrelled action sits in a channel. Changing the stock does not meaningfully change how the barrel is supported. Anyone who tells you a Tapco stock tightened their groups is telling you about the comb height and the length of pull, which are real, but they are shooter effects, not rifle effects.
Weight. Most chassis are heavier than the wood they replace.

13.8 The One Rule

Keep the wood.

Every original stock, every handguard, every buttplate, every bayonet, every sling swivel and every screw — in a box, labelled with the rifle’s serial number.

Two reasons. First, resale: a matching-numbers Russian SKS with its furniture in a box in the garage is worth substantially less than one wearing it, and the difference is more than the synthetic stock cost. Second, you will change your mind. I have put wood back on more of these than I expected to.

13.9 Which One I Would Buy

Beaten military rifle, want it usable and cheap: Tapco Intrafuse, bayonet-cut version. Under $80, no drama, keeps the bayonet.
Want a scope on it: ProMag Archangel or ATI Strikeforce, for the adjustable comb. Read Vol 14 first, because the mount matters more than the stock.
Want it short for a truck or a pack: ATI Strikeforce folder.
Want AR ergonomics and Magpul furniture: FAB Defense M4-SKS chassis, then whichever Magpul grip and stock you already like. Budget for the chassis and the furniture separately, and read Vol 17 on the parts count before you order the grip.
Matching-numbers Russian: leave it alone.
