So to convert your "featureless" AR to PCC, you just need to change out the mag follower/spring with 9mm kit and replace buffer with heavier buffer to go with the 9mm upper. Life is good. Have you considered using CMMG 22LR conversion bolt in your AR to shoot 22LR? I only shoot CP 22LR in my ARs for training drills/plinking but they sure are fun plinkers - https://www.primaryarms.com/22BA6AE 22LR still cheap at below $20/500 - https://www.thehighroad.org/index.p...15-20-500-shipped.853059/page-3#post-11359991 It was from Friday afternoon, March 29 through midnight April 5th of 2019 for 7 days. And it was not just 30 rounds but ANY CAPACITY magazine - https://www.thehighroad.org/index.php?threads/happy-days-in-ca.849757/page-4#post-11102503 That's why judge Benitez not only ruled but ruled WITH JUDGEMENT so his ruling went into effect immediately after ruling on Friday afternoon on 3/29/19 - http://michellawyers.com/wp-content...-2019-03-29-Order-Granting-Plaintiffs-MSJ.pdf "IT IS HEREBY ORDERED that: 1. Defendant Attorney General Xavier Becerra, and his officers, agents, servants, employees, and attorneys, and those persons in active concert or participation with him, and those duly sworn state peace officers and federal law enforcement officers who gain knowledge of this injunction order, or know of the existence of this injunction order, are enjoined from enforcing California Penal Code section 32310. 2. Defendant Becerra shall provide, by personal service or otherwise, actual notice of this order to all law enforcement personnel who are responsible for implementing or enforcing the enjoined statute. The government shall file a declaration establishing proof of such notice. DATED: March 29, 2019" And CA law enforcement had to enforce the ruling immediately and to this day, CA DOES NOT enforce the POSSESSION of larger than 10 round capacity magazines; only new sales, importation and manufacture.
