I have three of these barrels [FN 5.7] and they are of magnificent quality. I bought one to compare it to a competitor’s product. Jarvis I though was more accurate and out of the box drop-in. You cannot go wrong  with the Jarvis line of barrels.

…I received the two HK barrels I ordered and have ordered a third. I always thought the HK barrels were good. However, your barrels are better! I’ve really enjoyed them. Just wanted to thank you for what you do.

I have now tried the threaded Beretta barrel you made for me and it’s perfect. Great fit, looks good, and shoots straight! So, just wanted to say thank you for the great product
