Great product. Little cheaper than the metal version and worked great. The only issue i had was i had to tighten the swivel mount from the dove tail to the frist knuckle a bit because it would sink under weight which wasnt a big deal honestly. I would also suggest using blue locktite on the screw that directly mounts to the pvs-14 cause I did notice it started to back out a little. Note a huge deal but something to note. This ran through quite a few live fires and training lanes in the woods and was so better than the standard J-arm.

I haven't been able to test it thoroughly, but at first impressions it seems very solid and much more robust than USGI J-arms.
