Most Helpful Positive Review Worked well in Aero Precision M5 Lower
This release is a bit longer than the AR15 version. It's nice for DPMS pattern lowers like the Aero Precision M5. It is NOT for the AR15.. It is much too long. I'm buying more for my other 308 big bore lowers. I paired with the Aero button and spring.
Most Helpful Negative Review Waited months for this to ship and....
So I waited months for this to arrive. No that isn't an exaggeration. Finding a legit mag catch that is made specifically for a 308 and is therefore longer than a mag catch for a 5.56 lower is quite hard to find. Just my luck when I saw this item from optics planet! Except what I got was a mag c...

Perfect fit for Aero M5

by bob, Verified Owner from AL, United States Written on December 20, 2025
The stock catch on my aero precision 308 M5 was too short, this is the correct part for the wider 308 receiver.

Great catch dor rhe money

by Para-Shooter, Verified Owner from OR, United States Written on December 9, 2025
While it may nit be the most fancy high end catch out there, it's definitely a steal for the price paid. AR10 LPK's are notoriously expensive compared to the AR15 counterpart, the difference being the bolt catch and the magazine release. This budget buy allows to to be a bolt catch away from building an AR10 LPK at AR15 pricing

.308 mag catch

by Jesse Sellers, Verified Owner from GA, United States Written on December 20, 2023
Some of these .308 builds can be a pain. Sometimes you need a little bit more length on the mag catch. It’s only a hair longer, but with an extended button release it’s perfect!
Pros:
  • Works great price is good and it pairs well with an extended button release
Cons:
  • None

.308 Magazine catch - THIS IS EXACTLY AS ADVERTISED! It is .218" Longer than the AR-15 Mag Catch!

by Anthony Dew, Verified Owner from NC, United States Written on August 23, 2023
AS ADVERTISED, THIS IS INDEED a .308 MAGAZINE CATCH. The screw is .218" LONGER than an AR-15 Magazine catch. The person in the other reviews that claims it is an AR-15 mag catch doesn't know what he's talking about. He admitted to having a POLYMER LOWER! It most likely uses a much longer rod because they have to make the plastic lowers thicker in order for them to be strong enough and will require an Original Equipment Manufacturer's part for the mag catch. Optics planet should remove both of his ratings. He is misleading people by his ill informed FALSE CLAIM that this Luth-AR .308 Magazine Catch is actually an AR-15 mag catch! IT IS NOT! It is EXACTLY as advertised. It is .210" LONGER than an AR-15 mag catch, just as it should be! Definitely recommended!
AR-15 Mag Catch measures 1.250"
Luth-AR 308 mag catch measures 1.468"
(measured from the outside FLAT surface of both mage catches...apples to apples)
Pros:
  • well made.
  • .218" LONGER
  • Allows you to use all of the threads on the button!
  • Item was MADE FOR aluminum 308 lowers
Cons:
  • No Cons, but if you have a PLASTIC LOWER, it still may be too short. You may have to get a mag catch from the manufacturer of your lower.
  • The new buttons I had did go on tighter than usual. Almost like it was the wrong threads at first, but they did thread on.
Best Used for:
  • Best used for ALUMINUM .308 Lowers! A must IMO.

AR 10 .308 Magazine Catch

by Stephen White, Verified Owner from NC, United States Written on May 22, 2023
I wasn't sure if it was going to be the right one, but when I got it.....BINGO, perfect fit. I ordered the same part from the company I got the lower receiver from and it was still to small. But the part from Optics Planet.COM,
