A couple upgrades on both my OPAP and MPAP.
I added rear single point sling attachments to them both of them. The PAP guns are a little unique under the grip, so you got to get the right attachment that's specifixally for the PAP guns. I actually made the mistake and ordered two of the same attachments that fit the OPAP, NPAP & MPAP but not the MPAP when using the SB47 brace. So I went with the Echo 93 V3SB attachment for my OPAP with the SB47 brace.
I also added two new muzzle devices. I added a Tapco Slotted Muzzle Break for the OPAP as seen here:
And I added a CNC 4 Piece Bulgarian Muzzle Break and Flash Killer as seen here:
