Now there’s some discussion over whether this is a real phenomenon or not. From what I could see, on my rifle, it seems quite likely that the rear profile of the polymer magpul p-mag is touching the bolt hold open device just enough to raise it and have it interact with the bolt even when the magazine has rounds in it.
I believe this to be the source of the jams and failure to feeds I experienced previously.
This is a combined video of my review of the Leupold HAMR and the run and gun exercises I’ve done with it. Its a 4X32 scope and red-dot combo. The full (long) cut of the run and gun is right after the jump . . .
Well it seems like I’ve finally done something wrong to this gun. She’s failing with disturbing regularity. Sometimes the round doesn’t make it into the chamber, and instead get bit by the bolt. Sometimes the bolt cycles and doesn’t grab anything. Sometimes the bolt-hold open device fails to engage.
After some substantial troubleshooting, I determined damage had happened to my bolt and bolt hold open device, possibly due to resting on a magazine, but also potentially from the magpul p-mags that I’ve been using. You can see the way they interact . . .
This combination took me a while to set up. Installing the full length top rail was a huge pain in the ass but it allowed me to mount a 512 eo-tech and riser in front of my ATN Spirit. With a Gen 2+ tube its not the best NVD available, but its certainly a cut above entry level units. Using a 1x lens and picatinny mount in conjunction with the IR output of the Inforce WML means I can confidently engage targets within 100 yards.
While current generation Tavors come with a full length rail, I had to buy mine from Canada Ammo. Made by Ranch Tactical, this rail is certainly a cut above the NEA equivalent, but it does have some fitting issues still. The rail fits over the lower profile gas block, effectively removing the rear flip up sight and covering the IWI proprietary NVD or magnifier mount.
The night vision I’m using now came from this site here:
Sometimes its just nice to see a rifle being put to use. This is the TAR-21 Tavor rifle made by IWI (IMI) being fired in Alberta, Canada. Its a bullpup rifle that is stamped .223 but built to handle 5.56 calibers. One of the nice things about this rifle is that it takes STANAG magazines just like a standard M4 or AR15 rifle.
