Black Nitride Barrel Refinishing

I'm still in the process of assembling an upper with the new barrel, so cannot comment on performance. That said, I was very impressed with how easy is was to work with PM, their communications with me upon receipt and shipment, and the fact that they returned the product to me in about half the advertised production time. Based on an inspection of the barrel it appears that the nitriding was properly done and met expectations. Can hardly wait to complete the assembly and get this barrel out to the range for some testing.

I read positive comments about Primary Machine on some Glock forums and so decided to contact them. Great communication - Bruce responded to my emails very promptly and thoroughly answered my questions. The pricing is quite reasonable and the turnaround time on my parts was fast. I received email updates informing me they had received my order and again when it shipped, including tracking. I had a Black Nitride Barrel Refinishing and also custom Graphite Black Cerakote on my Slide Stop, Slide Lock and an Extractor. All the parts look great and my older model Glock looks almost new.

Quality Excellent

Sent my stainless steel barrel off to get Nitride treated and it came back beautiful! Big shout out to Bruce, he is the gold standard for customer service and for that Primary Machine has a customer for life now!

Great work! Definitely recommend.

Sent in 2 stainless barrels and a few weeks later I recieved them back, great job Primary Machine.

Barrel refinish on my barrel was perfect. Nice, even finish and was delivered right on time.

Great turnaround time, barrels look amazing - finish is perfect!

Received my barrel and was extremely happy with the way it looked. It was originally stainless steel. However, now it looks like a factory black barrel.
