What Affects the Value of an HK416?
The price of an HK416 is affected by its model, condition, upgrades, and accessories. Market demand plays a part too, of course.
Let’s go over those factors so we can price your HK416 more accurately.
HK416 Models
HK416 22 LR Price

The HK416 22 LR is worth around $200 to $400 used if a rifle, $180 to $380 if a pistol. Its MSRP brand-new is $749.
This is the one most US owners have. Fitted with a 16” barrel and the classic HK416 styling, it’s known as a gun that shoots flat and fun.
It comes in both rifle and pistol versions. The prices of used HK416 rifles don’t vary too much between them.
MR556A1 Price

The MR556A1 is worth around $1,400 to $2,200 used. Its MSRP brand-new is $3,499.
The older tweaked civilian version of the HK416, the MR556A1 is a semi-automatic rifle chambered for 5.56 NATO rounds. It’s made in the US and sports a 16.5” barrel with a Magpul buttstock and Modular Rail System.
Perhaps the most compelling part of this sporterized rifle is that its upper is compatible with lowers of the AR-15, M16, and M4 type. That’s why you’ll often see modded versions of it today.
MR556A4 Price

The MR556A4 is worth around $2,000 to $3,400 used. Its MSRP brand-new is $4,299.
An update of the MR556A4, it offers a lot of new upgrades. Most significant are the ambidextrous safety, adjustable gas block, and M-LOK handguard.
It’s also engineered to be slightly lighter than the A1 version.
HK416D SF Price

The HK416D SF is worth around $14,000 to $25,000 preowned due to extreme rarity.
Meet the unicorn! This is the rarest HK416 rifle in the US and the only true semi-auto HK416 if we go by official name.
Now, the HK416D SF isn’t likely to show up in your average used gun marketplace… but it’s still worth discussing for its legendary status. Only a few of these were ever imported to the US. In fact, they’re so rare that most people in the gun industry know who owns the existing ones!
These guns are German semi-auto HK416s imported and used by LEOs (law enforcement officers). Since most had 10.4” or 14.5” barrels, they were classified as short-barreled rifles by the NFA.
So, surplus guns sold to civilians typically had to be altered to be at least 16” instead. With only about 300 of these imported into the US, intact ones are very rare.
Only 7 of the 10.4”-barrel ones are known to be civilian-legal here. Of the 14.5” ones, it’s around 15. That contributes to HK416D SF pricing – and forgeries.

- Aesthetics: Absolutely perfect
- Function: Absolutely perfect
- Value: The highest prices for preowned guns, usually 90% of MSRP
Excellent
- Use: Fired rarely enough to count
- Aesthetics: Close to perfect unless you’re looking at it very closely
- Function: Perfect

HK416 Upgrades and Accessories

Some upgrades can bring value up. Here are the ones we see most often. All figures are for upgrades or accessories in good condition.
Sling
A popular adjustment to make toting either gun more convenient. Even on the lighter HK416 rifle, slings are appreciated. Expect the sling to keep 30% to 50% of its value.
Examples:
- H&K MR556 and HK416 Tactical Sling - Around $23 to $38 used
- Vickers Padded Sling - Around $22 to $36 used
Foregrip or Hand Stop
These are added to improve control and help users avoid heat from the gun in use. Both gun models use MLOK rails for this area, by the way. Expect value retention of 30% to 50% for a good HK416 handguard or foregrip.
Examples:
- Blue Ridge HK Assault Grip (Vertical) - Around $20 to $32 used
- Magpul M-LOK Hand Stop Kit - Around $7 to $12.50 used
Stock
Upgrades for this don’t happen much to the HK416 22 LR. Even in the MR556s, they’re not common.
That’s probably due to how well the big HK416 stock balances the heavy front of the MR. It’s usually more about customizing the look instead. Since it’s not often a functional upgrade, expect value retention of just 20% to 40%.
Examples:
- Bravo Stock - Around $12 to $30 used
- Magpul CTR Carbine Stock - Around $13 to $32 used
Spare Magazines
The restrictions for these will obviously vary by state, but you can get magazines with as many as 30 rounds in them for these guns. These are usually popular additions to guns for resale too.
Examples:
- HK416 22 LR magazines - $10 to $15 per used mag
- MR556A1 magazines - $18 to $25 per used mag
