The Picks, With a Verdict on Each
Best Overall and Best Ambidextrous: Strike Industries Ambi Magazine Release
The magazine release on an AR-15 is two parts. The button you press sits on the right side of the lower, and it screws onto a catch bar that runs through the magwell and hooks a notch in the magazine. Push the button and the catch swings clear, so the magazine drops.
An ambi release replaces the whole catch, not just the button. Strike's version adds a lever on the left side of the lower, so a left handed shooter can drop a magazine with the trigger finger. A right handed shooter still has the button.
The black Strike release took 24.3% of mag release picks, the most of any release by a wide margin. The FDE version took another 4.3% on its own. If you shoot left handed, or you want to drop magazines without shifting your grip, start here.
What we like
- Strike says it drops into any receiver designed to accept a mil-spec magazine catch.
- The package includes Strike's own enhanced release button and spring, per the listing, so it's a complete swap.
- Strike describes it as low profile, built so it won't activate by accident or interfere with other controls.
- It's about $38 at all six stores we track that have it in stock.
Watch out for
- At about $38 it costs about four times a button upgrade.
- You'll have to remove the old catch to fit it, so the install takes longer than a button swap.
- The card shows black. FDE, red and Titan are separate listings at about $37 to $40.
Best Budget Ambi: CMMG Zeroed Ambi Mag Catch
CMMG's catch does the same job as the Strike: it replaces the mil-spec catch and adds a lever on the left side. CMMG calls this version the Zeroed. Its listing says it adds an extended release bar that gives you more leverage. You screw an adapter button onto the catch, then attach the button extension to the adapter.
It took 14.8% of mag release picks, second only to the Strike. It suits a left handed shooter who wants ambi control and a bigger button for a bit less than the Strike.
What we like
- CMMG's listing describes steel construction and a serrated surface on the extension for grip.
- The extended release bar gives you more leverage than a mil-spec button, per the listing.
- CMMG backs it with its Lifetime Quality Guarantee, according to the listing.
- The cheapest stores we track ask about $30.
Watch out for
- Prices spread a lot. Four stores ask about $30, three ask about $38 to $41, and one asks about $55.
- The listing names the catch as 55AFF6E but also mentions a catch and button kit, 55AFF89, so confirm with the store what's in the box.
- CMMG's plain ambi catch, without the extended bar, is a different listing with its own price.
Best in Color: Rise Armament Magazine Release Button
Rise's button is a quick way to add an accent color to a black lower. It replaces the mil-spec button and threads onto the catch you already have.
The red Rise button took 13.8% of mag release picks, third behind the two ambi catches. Pick it if your build already has a red trigger or safety, or if you just want the cheapest button on this page.
What we like
- It's aluminum with an anodized red finish, per the listing.
- Rise calls the shape extended and ergonomic, made for reloads with gloves on.
- It's about $8 to $10 at the stores we track, and five of them have it in stock.
Watch out for
- The listing gives a width but no height, so you can't compare its size on paper with the Seekins.
- It replaces only the button, so it adds nothing for a left handed shooter.
- Red isn't for every build. Rise also sells silver and blue versions at about the same price.
Best Budget Catch Assembly: TPS Arms AR-1031 Mag Catch Assembly
Sometimes you need the whole catch. Not a nicer button. TPS Arms sells this as a mag catch assembly for the AR-15, a plain part for filling a stripped lower or replacing a worn catch.
It took 4.4% of mag release picks, fourth overall and the most picked plain catch assembly. Buy it if you're finishing a lower on a budget and don't need ambi controls.
What we like
- It's about $8 to $12 at the stores we track, the cheapest way here to replace the whole catch.
- TPS lists it as an AR-15 mag catch assembly in black, part AR-1031.
Watch out for
- Neither TPS listing we track says which parts come in the assembly, so check with the store before you count on a new button and spring.
- One store asks about $18, so check the card for the cheaper listings.
Best Billet Button: Seekins Precision Billet Magazine Release
Seekins made its button bigger than mil-spec. The listing says it's larger and easier to work than the standard button, with a diamond textured face and a blind threaded hole that keeps the outside clean.
It took 2.6% of mag release picks. Choose it if you want a little more button under your finger without stepping up to a paddle.
What we like
- It's CNC machined from a solid piece of 6061-T6 aluminum, per Seekins' listing.
- The listing says it fits any mil-spec AR-15 lower.
- It's about $9 to $11 at most stores we track.
Watch out for
- The listing says the finish is soft coat anodized, not hardcoat.
- It only names AR-15 lowers, so check before you put it on a .308.
- One store asks about $20, so check the card for the cheaper listings.

Most Picked Magazine Releases
Share of magazine release picks, July through September 2026
| Item | Share (%) |
|---|---|
| Strike Ambi Release Black | 24.3% |
| CMMG Zeroed Ambi Catch | 14.8% |
| Rise Armament Red | 13.8% |
| TPS Arms Mag Catch | 4.4% |
| Strike Ambi Release FDE | 4.3% |
| Odin Works XMR | 3% |
| Seekins Billet Button | 2.6% |
| Phase 5 PMR Gray | 1.8% |
Two of the top three releases in our data are ambi catches, and the Strike alone took more than the Rise and TPS parts combined. The red Rise button was the only plain button swap in the top four.
- A button swap like the Rise or Seekins changes texture and size and nothing else. It takes a couple of minutes and costs about $10.
- An ambi catch like the Strike or CMMG adds a left side lever. You'll need it if you shoot left handed, or if you want to drop a magazine with your trigger finger.
- An oversized paddle like Odin Works' XMR, about $20, is easier to hit fast, but you're more likely to bump it when you set the rifle down or press it against cover.
To change a button, push it in and turn the catch on the left side of the lower until the button unthreads. Most mil-spec lowers take any of these parts. If you're building on a billet lower, check its maker's notes before you order an ambi catch.

FAQ
Frequently asked questions
What is the best AR-15 magazine release?
- The Strike Industries Ambi Magazine Release was the most picked magazine release on GunPartPicker, with 24.3% of mag release picks from July through September 2026. It replaces the mil-spec catch, adds a left side lever, comes with Strike's own button and spring, and costs about $38.
Do I need an ambidextrous mag release?
- If you shoot left handed, yes. A right handed shooter can run the standard button with the trigger finger. The Strike Industries Ambi Magazine Release, at about $38, was the most picked release, and CMMG's Zeroed ambi catch costs about $30 to $40.
Is an extended magazine release worth it?
- A textured or slightly larger button is a cheap upgrade, about $8 to $11, and it gives your finger more grip. A large paddle is easier to hit fast but easier to bump by accident. CMMG's Zeroed ambi catch, the second most picked release, adds an extended release bar.
What is the best budget AR-15 mag release?
- The Rise Armament button costs about $8 to $10 and was the third most picked release. TPS Arms' AR-1031 mag catch assembly, about $8 to $12, was the most picked plain catch assembly. For an ambi catch on a budget, CMMG's Zeroed catch starts at about $30.
Do AR-15 mag releases fit AR-10 or .308 lowers?
- Not all of them. Seekins only names AR-15 lowers, and Strike lists its ambi release for standard AR-15 and M16 receivers. Check the listing for your platform before you order.
How do I install a new magazine release button?
- Push the button in, then turn the catch on the left side of the lower until the button unthreads. Thread the new button on until the end of the catch sits about flush with the button face, then test that a magazine locks in and drops free.
