    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    I’m intrigued. Low height barrier openings are a problem for me because my scope physically is taller than most, even with only a quarter inch clearance over the barrel/receiver. Is the Armaflex sufficiently compressible for a scope mounted this low? Your solution is simple and sure could take...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    When I use this udder bag attachment as shown in the previous pictures as a substitute for a bipod, it is a little too low for comfortably firing from a supported prone position on the ground. It is workable for supported prone from the bench. I wrapped a 2” Velcro tie around the legs to keep...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    Since my last post on this thread, Cole-TAC has marketed the Backbone Bag Frame. It is a Picatinny version that uses the American Defense mount. This may make making your own Picatinny flat plate/AD-170 mount previously described in this thread a mute point. However I wanted to use a...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    Attached are several pictures showing the adapter attached to one end of a 4x7 plate. The plate is oriented extended back towards the shooter and with a flat bag attached. The stock has a short forearm and the bag almost reaches the magazine. From the bottom of the stock to the bottom of the bag...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    Problem solving. I’m always amazed at the ways things can be solved that I could never have thought of! Congratulations. When the spring modification is fine tuned, would you please add a picture of the final assembly mock-up or does the above picture do that job now? Did you continue to use a...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    I agree. The short magazine is too short to be workable. Here’s a measurement to consider. When I used a 20 round magazine and cut the spring down, with the follower simply resting on the spring, there is just under 2-1/2” clearance left for the insert before any spring tension comes into play...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    Keep in mind that most factory blocked magazines are not designed to be opened and removing the “permanent“ seal may also cause problems because of state regulations. This may preclude access to the spring for reducing the length for a more reliable feed. A work around is to use a Black Dog...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    Here’s another idea. The conversion insert extends down about 3-1/4” from the top of the magazine. How long is your”short” 10 round magazine? Can you post a picture of the short mag with the insert laid in position on the outside (similar to one of the pictures I just posted). I am concerned...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    Let’s see if these pictures help. The first picture shows the position of the front tab. It is in line with the front of the mag. I took the picture so it would show this correctly and without distortion. The middle picture shows the angle of the insert within the mag through the catch opening...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    I have also tried removing the follower and letting the spring hug the 22 feed insert. This was a common suggestion for something to try years back. I could never get it to work. I concluded that everything was too loose and the insert was not being held in a proper alignment to feed. The...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    I actually use both the Short Action Precision sand filled cylinder and and sand filled Wiebad Cookie. Both are very heavy and smash down stable on a narrow or pointed barrier. They wedge securely between the plate or bipod (depending on stage I can’t always substitute plate for bipod if bag is...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    Where I shoot, probably less that half of competitors have ARCA rails. Picatinny still predominates. As stated in the opening post, the intent of the post was to show a “quick solution” that would allow shooters to use the existing picatinny rail and construct other forms of support to replace...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    I’m still trying out different size bases. Using the same picatinny rail adapter, drilling a recessed 1/4” hole and cutting the screw to the correct length is all it takes. There is no limit to what will work. Here’s another. I used a 3/8x3-1/2x5-1/4” piece of aluminum. A 1/4” rubber pad was...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    This may be the answer to your question. Today the Area 419 website has the bare Rail Changer arm in stock. The description within the listing says “It will NOT work with other clamps, it will only work with the Area 419 ARCA clamp”. Of course there is always the option to use the bare Rail...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    Here it is mounted longitudinal. See Photo. There is only one screw (1/4x20) that mounts the tripod/camera adapter to the aluminum base plate. The two threaded holes just lateral to the 1/4x20 screw are used for the two recessed flat head screws that hold the quick disconnect (AD170S) to the...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    I didn’t have a railchanger piece but I did already have a AD-170S and aluminum bar and the bag only so it was less expensive for me to order the tripod adapter insert (about $20) and make the attachment. I hope someone can answer your question though. That would be a easy solution for the...

    Adapt Armageddon GripChanger Bag for attachment to Picatinny rail for NRL22 barriers

    The 1-1/4x3x7” Armageddon GripChanger bag factory mount is only available for ARCA rails and my Vudoo 22 has a Picatinny rail on the underside of the stock. Here’s a quick solution that uses a 7” section of a stainless steel ruler, a 1/4x2-1/2x7” aluminum bar, the American Defense BT56-L quick...

    Shorten Black Dog Polycarbonate Plastic Magazine

    The Black Dog magazines I use in a AR15 lower with a 22LR conversion upper are only available in the longer length (both 10 and 25 round models). I cannot use them when shooting prone or from the bench because of the length. I only load with a maximum of 10 rounds. The following is a quick way...

    Solution for CLE 22LR upper misfeeds using M261 AR15 mag inserts

    Now that I have made this modification in a number of magazines, I need to point out another variable to consider when deciding how much spring to cut off. Not all springs have equal force. If there is too much force, i.e. the spring is too long, feed problems can occur. Measuring with a Wagner...
