Re: POF 308 GTG or JUNK?
There have been a lot of people bitching and moaning about various "issues" with POF, its management, QC, Frank (the owner), etc., but my 20" SPR P-308 has been 100% since day one. It has eaten everything I have fed it and come back for more. In terms of accuracy, it is just scary for a gas gun. With BH and FGMM 168gr loads and my handloads, it is a sub-3/4 MOA rifle which I am sure is due in no small part to the Rock 5R 20" barrel. I have not done any load development with heavier, 175gr loads yet, but factory BH 175gr stuff was sub-MOA as well (only 40rnds fired).
The only "problem" I have had with mine was some failures to feed which were wholly a result of two bad DPMS mags that wouldn't feed properly and caused issues. I have run other DPMS mags and C-Products mags with zero problems.
The only other issue, which is common to piston driven rifles like the POF, is some minor "gouging" of the upper receiver by the cam pin as the carrier cycles. Most people who have experienced this issue seem to agree that is does not continue past a certain number of rounds. The same issue is apparent in the LWRC and other rifles too. POF is currently about to intro a roller cam pin that will eliminate this issue altogether. In the meantime, before firing a round from mine, I installed an Adams Arms bolt spring and I have had almost zero gouge on my upper.
If you can read through all the name-calling, horseshit and general garbage, POF's industry forum on AR15.COM has some pretty good info.
