I incorrectly posted nearly the same question in AR Discussions having glossed over this Piston forum so here it is again with slight modification.
"Yes I tried to do a forum search and had poor results. I am strongly considering a PWS 16" piston upper to go on a three year old Daniels Defense DDM4 which of course is a Direct Impingement gun. I think that I can keep my standard Buffer and spring and the only thing I need to do would be switch uppers Am I missing something? In the other forum it was suggested I might need a "Piston Kit" I know nothing about such a 'kit'. This is the Warden's (wife) gun and she won't be pleasant if it doesn't run. No I won't sell the DD Upper. I buy guns and parts, I don't sell them. Thanks for your help! |

If you swap uppers, to that of the PWS, you don't need to buy any kits. PWS doesn't sell their piston setup separately, so you will have to purchase a complete upper.
Push pins, pull off old upper, put new on and push pins back in. You may look into putting a heavier buffer in, depending on your barrel length, ammo choice and suppressed plans. |

Okay Thank you. I am not thinking of a suppressor, at least in the near term, She did well with her DDM4 in our 4 day Front Sight Course so maybe I should leave it alone except for the trigger (Regular GI trigger)
I do have a new two stage Ruger trigger on hand right now, I do intend to build a 80% lower and I could put either upper on that. I want her to have the best I can provide. |
