Hi, The product sheet for the 30P-1 says "limited" semi-auto. http://www.thunderbeastarms.com/pdf/TBAC-30P-1.pdf I plan to use the 30P-1 on my AR. I'm not going to be doing mag dumps, but I will be doing some action type shooting where you shoot 20 rounds in a course of fire which takes less than a minute. The time between courses of fire is about 45 minutes depending on the number of shooters. Will that be OK? Thanks.
