The MasterPiece Arms or MPA Defender is probably among the most popular MAC clones. Some call it the poor man’s knockoff of the classic bad-guy guns from films of the 80s and 90s.

Despite it being a “poor man’s model,” you can get decent prices for this gun even now. If you want to sell yours, read on. We’ll cover used pricing for the MPA Defender in its 9 mm and 5.7x28 mm versions.

PS: If you're checking its value to sell your gun, ensure you follow federal rules. Read our guide on how to sell a gun online to stay 100% legal.

Current Value of an MPA Defender

How much is an MPA Defender today? The average used MPA Defender is worth $210 to $440, though prices vary. The highest-value variants are the MPA30DMG 9mm and the MPA57DMG 5.7. The lower end of the gun’s used price range is often for the MPA30T variant. That’s the most affordable version Masterpiece Arms makes, and is 28% cheaper than the highest-end ones even at retail (brand-new, $540 vs. $750).

How We Calculate Used MPA Defender Values

MPA Defender price is affected by its condition, variant, and upgrades.

MPA Defender

Condition and Value

Like most other guns, Defenders sell best when they show less signs of wear. To get an accurate value for yours based on this, get it professionally appraised. We can do it for free!

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

But if you want to try appraising it yourself first, use these condition tiers and their values:

New or Mint

In this state, it’s never been modified or even used. It’s basically lived in its box ever since purchase. These Defenders can bring in as much as 90% of MSRP.

Excellent

These have almost never been used and it shows, because they’re nearly perfect. These Defenders can bring in as much as 80% of MSRP.

Very Good

These have been fired but only rarely, to the point where you can nearly count the wear and handling marks on the gun. Sell these for up to 70% of MSRP.

Good

These have been used regularly but they’ve been pampered by their owners too. Stored well, cleaned often, and kept in good shape, they bring in up to 60% of MSRP.

Fair

These have been used regularly too but are beat up and not cared for. They should still generally function, however. Sell these for up to 50% of MSRP.

Poor

These are the worst cases, usually defective or even outright broken. A Defender in this state will typically fetch very little, at most 40% of MSRP.

How We Appraise MPA Defender Models

There are several MPA Defender variants. The most popular is perhaps the cheapest one, the 9mm MPA30T.

If you want to know how much yours is worth, we’ll cover the usual prices for each one below. Again, keep in mind that these price ranges are estimates and can change due to market trends.

MPA30T

The average MPA30T is usually worth $210 to $350.

This Defender is a 9 mm pistol that retails at $540. The top-cocking mechanism and lack of a sight mount differentiate it from the higher-end variants.

MPA30T-GR

The average MPA30T-GR is usually worth $230 to $370.

This is actually the same gun as the MPA30T, but with a cerakote Grim Reaper paint job. It retails at $568 and is less common than its non-cerakoted sibling.

MPA30SST

The average MPA30SST is usually worth $250 to $380.

This tier introduces the first side-cocking Defenders. It also adds a scope mount as well as aluminum machined parts to the design. This one retails for $609.

MPA30DMG

The average MPA30DMG is usually worth $300 to $430.

Based on the SST but equipped with a grip that accepts Glock 17 and 33 mags, it also adds a low-profile mag release, lower rail, and upgraded “Decal Grip” panels. It’s cerakoted black and ships with a special MPA polymer case. Retail pricing is $750.

MPA57DMG

The average MPA57DMG is usually worth $320 to $440.

This is the 5.7 version of the 30DMG, retailing for $750. It’s compatible with FN57 mags and is a side-cocking semi-auto with black cerakote finish and a 5” barrel.

This is a model that holds value well. Because it’s a premium firearm in the line, we use a secure gun shipping and buying system to ensure every transaction is fully insured and legally compliant.

How Upgrades Affect What We Pay for Your Defender

Some upgrades to the MPA Defender can increase the gun’s value.

It’s always dependent on the buyer, of course, as well as the condition of the upgrades. Here are some examples of common value-adding MPA Defender accessories. Note that the estimates for value retention are for items in good condition!

Brace

An MPA Defender brace can boost the gun’s stability, so it can be attractive to buyers. Folding braces are especially valuable. A3 Industries’ modular options retail from $199.95 to $249. 95, for instance.

Just keep in mind that some braces can turn the gun into an MPA Defender SBR (short-barreled rifle). That’s an NFA-regulated gun, which limits your buyer options.

You can take the pistol brace off to sell it as a handgun. However, if you still want to sell it as an SBR, try us – we’re licensed to buy NFA items.

Value retention of upgrade: Around 30% to 50%.

Stock

The MPA Defender stock variants most often seen on the used market are MPA’s own. These retail for about $129.99.

Like the braces, these make the gun trickier to sell because they turn the gun into an SBR. In fact, this applies to all stocks despite not applying to all braces. Again, try us if you want to sell the gun with the stock, as we can legally buy that.

Value retention of upgrade: Around 30% to 50%.

Drum

MasterPiece Arms itself makes the MPA Defender 9mm drum. With 50 rounds, it’s appealing for any buyer interested in the gun for extended range fun.

Value retention of upgrade: Around 20% to 40%.

Spare Mags

An extra MPA Defender magazine or two can also sweeten the deal for your buyer. These go for $35.95 retail from MasterPiece Arms itself, but depending on your variant, other mags may fit.

Price per mag: Around $7-$10 for the MPA Defender 9mm magazine, $9-$12 for the 5.7mm.

General Questions & Answers

The MPA Defender can be a good gun, but it depends on what you’re looking for. Previous iterations were widely reported as having trigger slap, but the latest ones are smoother.

The Defender isn’t actually a MAC, as it’s made by a different company. It is a MAC clone, however, so it’s based on that classic design.

One variant of the MPA Defender, the MPA30DMG, takes Glock mags. There’s also a special grip you can buy from MPA that makes it possible for the 30T and 30SST variants to do that.

For the MPA30T variant of the MPA Defender, the barrel is 5.5” long.

Still determined to sell your Defender? Reach out to us and get an estimate for free. We’ll even pick up whole gun collections with that gun, in many cases.
