Reviews & Ratings for Kinetic Development Group SRX3 Stribog 3in Receiver Extension — 2 reviews — Page 1

I bought this item after it checked all the boxes I wanted for my stribog. I was looking for them for weeks with no luck. Super happy they were back. I wanted something with some extra length and to tuck a suppressor for a nice clean look. Lots of options out there but I liked the look and the increase to the size in diameter to get a better hand hold c clamp on. I was nervous after reading the initial review however the guy above didn’t do his homework on the product before purchase. It’s not for the shorter stribog version s. You would need the barrel extension kit for that. It works on the standard size barrel. I spoke on the phone with the KDG Company prior to ordering to ensure fitment. When the last time you had someone pickup the phone and say hello without running around a call center. Very refreshing ! Had a great short to the point talk. I’ve since bought their quick detach rails as well. They are very high quality machined and do not regret my purchase. I did get a tri lug adapter to make take on and off easy rather than direct thread.

First off, it seems strange that there is no mention of the issues with using this with a 5" barrel. But I suspect it is the manufacturer trying to keep the flaws as unspoken as possible. While you can technically put this on a 5" barrel, it will be missing the rear attachment points leaving this unstable and not able to be trusted.
I couldn't even install this accessory as the quality control for this item is clearly a joke. There is a locking collar that you attach to the barrel that is the front support for this extension. One of the screw holes were so poorly drilled that the screw sat at a 45 degree angle and was unable to seat properly. This would have been absolutely obvious to the person making the mistake. They clearly didn't care. And obviously no quality control or they would have seen the jacked up screw hole (it is a very visible defect) I am terribly disappointed and will not be supporting this manufacturer.
