This is a testimonial from a warhorse. From our boss' good friend, Señor Perry Punla. Allow us to share what Señor Punla posted on his and on PPSA pages. Just be informed that UDMC retrofitted Mr. Punla's M4-PDW with an earlier version of the PVAR gas-piston system prior to the implementation of R.A.10591. We still can retrofit any licensed AR rifle into a PVAR system but we can no longer replace the barrel and the bolt head unless given prior approval by FEO. And after retrofitting, it must once again undergo ballistics testing, if the bolthead and/or barrel were replaced. But if the barrel and bolthead are still good, no hassle, we will retrofit but again your AR must be licensed.
