I have a Colt HBAR Sporter which is the only AR platform legal to own in NJ due to it’s place in the CMP. I’ve gathered a couple dozen 10-round D&H steels and never had any issues with them. Ain’t NJ great?FINALLY bought an AR15. Its a new Colt Carbine of sorts. What are the best mags to buy? Or stick with Colt mags?
