Shawn's Review of Gemtech Suppressed Bolt Carrier Drop-In Replacement 5.56mm 4347825

As an leo and prior mil I have been fortunate enough to test a very wide variety of products. It is rare that you run across a product/system that actually works and improves performance. I run a Daniel defense mk18 suppressed and I can truly tell you that this works. Reduces recoil, no gas in the face, and ejects the rounds exactly where they're suppose to go. I was very hesitant to try this out due to the fact that the price is steep and the fact that I have read a ton of mixed reviews. Definitely happy I took the chance on this. I shot approx 1500 rounds testing this product out. I had two bolts on hand, my stock Daniel defense bolt and this gemtech bolt. It was a pain in the a** but I alternately bolts literally every two mags or 60 rounds. I shot suppressed at all times. I can honstely say that for my rifle specifically (dd mk18 10.3" barrel ) that I could 100% tell the difference at all times. IT WORKS! I had no malfunctions of any sort and next range trip I'm going to take a decimal meter because I swear it also lowered the sound signature while shooting. I might be crazy but myself and two others all thought the same.
Pros:
  • No gas face, less recoil, less sound signature, smoother shooting
Cons:
  • Not full bolt carrier group, little pricey
Best Used for:
  • Shooting suppressed
Would Recommend: Yes
