Reliable magazine - Brenton USA Long-Load AR-15 204 Ruger 17 Rounds Rifle Magazine

This is the third .204 Ruger magazine that I purchased from Optics Planet. The magazine comes installed with a plastic block inside the magazine that limits the magazine capacity to 5 rounds. You need to remove the bottom plate of the magazine to remove this block to make it a 17-round magazine. It’s pretty easy to remove. It’s handy if you live in a state that has magazine restrictions. This magazine is the only one that is specifically made for the .204 Ruger cartridge. Regular 5.56/.223 magazines work, depending on the make of the magazine but I’m trying to stick with magazines that specifically work with the .204 cartridge. The magazines are well made and durable with a nice finish. They look like standard 5.56 20-round magazines. Possibly the follower is shaped differently. I’m hoping that some day someone will come out with a magazine for the.204 Ruger with a higher capacity, but until then, this is a good option.
