I tried using the TSC plates, its not going to work, what you need to do is shorten the bolt catch spring because the magazine plate has to overcome the force of that spring in order to engage the bolt catch... Also, you need to file down the horizontal section of the "L" on the bolt catch like the one for the closed bolt system. Removing this section maximizes the contact area between the bolt stop and bolt as shown below. My bolt catch has been working flawlessly after some modifications. If you want, you can also add spacers or washers in the buffer tube to short stroke the gun so that the bolt catch can catch the bolt immediately/quickier when it begins its return cycle. Also, adding washers/spacers can lessen the impact on the bolt catch.
