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.
I had a chance to talk with Brian at the Calgary Shooting Center about his restricted .308 rifles, the MR .308 and the Knight’s SR-25. We only talk about the MR .308, but they are both gorgeous guns to shoot.
These are still very much available in Canada. Keep in mind that we never touch 416 or 417 parts though. Just the MR223 and MR308s. The 416/417 are totally different platforms. (Well subtly different. But different enough that they are incompatible) which is why the MR308 is restricted and not prohibited. FN’s SCAR on the other hand: the civilian version can take military parts, and as a result it was listed as prohibited when the RCMP classified it.
Yes, the MR308 is restricted as an AR-15 variant.
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:
I spend some hands on time with the VOTRS kit, and try a few variations outside what ships in the box. Designed for long term viewing, the VOTRS kit combines both mid and high power optics in one system. It’s worth noting that I did not order a kit directly out of the catalog. I built mine over the course of a year picking up one part at a time. As a result my combination is different from those sold directly from Vortex.
I assembled this over 2 years, mostly of stuff bought from Wholesale Sports. The case itself I had to special order from vortex. They no longer sell VOTRS kits as a retail item, but they will still custom build them for anyone who asks.
This video was shot approximately a week after I finally picked up my Tavor. Lots of people told me this was an IMI rifle, but its stamped with an IWI logo right on the side, so I’ll proudly argue anyone who wants to that this is manufactured by Israeli Weapons Industries and not Israeli Military Industries. More on that later.
This rifle has changed a lot over the year that I’ve had it. While it started out like this, it’s now quite different. At the time I could only afford a Vortex Viper PST 1-4, but now I use a Vortex Razor 1-6 and find it a much better fit. I’ve also put a full rail and iron sights on the top to make it a more flexible system.
I still use the JBM ballistics calculator every chance I get, and take the Razor HD Spotting Scope with my everywhere. I’ve traded the Leica rangefinder for a vortex one too, and while I like to use the Eberlestock, its getting a little to small for the very wide profile of the Tavor.
