About the Echo1 M4 Magazine Catch

This is a replacement magazine catch for M4 style guns. This is a direct replacement on Echo1 M4s (N4 Mk18, ST6, Stag Arms series, Robinson Armament polymer XCR series). Some fitting may be required on other brand AEGs but for the most part will be compatible with many brands of M4s that use a non-ambidextrous completely standard M4 magazine catch. Airsoft guns that see rigorous use may have these loosen up and fall out or the threads may eventually strip if you take your gun apart, so this part has you covered. Certain entry level or low priced M4 AEGs may also resort to using plastic magazine catches as a cost saving measure. This is a metal upgrade that will last a fair bit longer than an all plastic unit.

All that is required to install is a simple metric allen key (1.5, 2.0, or 2.5mm... this sometimes changes with each batch from the manufacturer so be prepared and have all of those). Do not overtighten the screw because the threads are very easy to strip. This is true regarldess of the manufacturer due to the very fine threads found on these magazine catches. Just a simple hand tighten should be enough, but add blue loctite to keep it all secure and from falling out in the long run. We will not accept returns on stripped magazine catches that were damaged by user error during install.

Echo1 USA is a well established brand that goes back to the infancy of the airsoft scene in the US. Providing some of the best value for the money, the emphasis of Echo1 has always been in the perspective of equipping people to play with gear and guns that is actually meant for hard use and not just for show. Echo1 was also first on the scene at a time when airsoft guns were even more expensive than they are today.

If you need help or consultation on repairs you could give us a ring at (888)316-7816 or shoot us an e-mail at sales@foxairsoft.com . Although we only offer tech work to our local walk-in customers, we would still be happy to point you in the right direction. The senior staff and owners of the company have been playing for well over 15 years and certified and authorized by several major manufacturers to do OEM quality repair and warranty work.

Note: Fox does not warranty or accept returns for parts that have been installed/attempted to be installed.

Note: Due to varying manufacturer tolerances for gearbox internals, parts compatibility no matter what version might NOT fit even if it is supposedly correct and fitment is NOT guaranteed. The reality is that some parts may need fitting and some parts might look the same but the dimensions are slightly different enough to not work. This will require technical experience to identify to overcome.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
