14 Reasons not to buy anything from Blackthorne Products!
#1 I ordered a complete .308 upper and lower parts kit to match an Armalite lower and was sent an upper that matched DMPS style...
#2 They would not respond to my requests for replacement.
#3 So...I bought a DPMS lower to accommodate their mistake, fired the first round and the bolt jams itself so hard into the breech that it took a screwdriver to remove it...
#4 Gunsmith checked headspace and said it was short chambered by .005 as it wouldn't close on a go-gauge.
#5 Gas port misaligned with gas block and port was .031 forward of the index mark on the barrel step.
#6 Before initially firing the weapon, there was a highly visible bur in the barrel from drilling of the gas port...
#7 When Blackthorne finally responded to me via the Better Business Bureau complaint that I filed, they claimed the malfunction was due to my modification (what modification, changing my plans and buying different lower?) and they stated the upper had been test fired before shipping and worked perfectly...Hmmm, nice bur. Must have happened after the test firing. Dishonest.
#8 the extractor retaining pin is improperly size and is loose and falls out.
#9 The bolt has crude grinding marks on it to accommodate the misaligned extractor.
#10 Bolt shows chipping near bolt cam pin.
#11 Gas block had punch marks from installation of gas tube roll pin.
#12 Inferior anodizing of upper
#13 Trigger and disconnector were received with mating surfaces that were crudely ground and when lower was tested with another upper, a double fire situation occurred several times.
#14 Their customer service sucks...
Bottom line, never do business with this company...learn from my experience.
