G&P M14 DMR - absolute junk. My gripe with my G&P experience is likely well known, and disagreed with by some, but i'll stand by my "not recommended" classification. Gearbox (blew from the start), receiver (broke in half, porous pot metal) and other metallurgical and major QC issues rendered mine junk by the end of it's first game. Spending some time researching (which i should have done before buying) will show others have had similar issues with the G&P M14. The M14 was produced in 2008, so perhaps it's a QC issue that goes back some time from the present, and things have improved since with G&P's other gun models.
I have no other experience with G&P's other gun models in it's product line, so cannot comment further.
