I have a PSA LRHO Glock lower and LPK on order with the intention of building an AR9 pistol and eventually turning it into a SBR. My question pertains to what upper receiver I can/should use in conjunction with the lower. If I understand it correctly I can use any standard AR upper, correct? It seems like most of the pistol specific uppers (NFA, JoeBob, etc) are currently out of stock. What about the gas tube port? Will excess gasses escape from that hole and effect function?
Thanks for your experience and insight. |

Try telling that to a lefty, haha! If you're right handed then they (deflector) are not needed. Quoted:

A 9mm upper typically has a no dust cover and a modified brass deflector but neither feature is absolutely necessary. You got me! |
