The 6mm BR cartridge and its variants are legendary in the rifle competition world for their inherent accuracy, easy loading, long barrel life and low cost to shoot. The only hitch was making the cases feed and function in a repeater. Part of the problem is the ejection cycle but for those with actions that can handle the small case feeding them into the chamber is the next issue.
The Patriot Valley Arms magazine conversion kit offers shooters the option to use standard AW 10rd magazines with a block spacer that also acts as a follower guide by channeling. These spacers take only the most modest of tools (a plastic or rubber mallet) and less than a minute of time to convert the magazines back and forth from full length 308 size cartridges to shortened 6 BR type rounds.
The Patriot Valley Arms spacer requires the user to trim the OEM follower but for AW mag users with Dasher aspirations this is the ticket! The spacer uses a guiding channel to keep the follower from "wandering" through the magazine body and rolling left to right during stacking. They also feature Patented DirtSwipe (TM) geometry to aid magazine reliability in dirty, dusty, or otherwise adverse conditions.
These spacers are fully CNC machined from high lubricity plastic. The internal length change supports cases up to ~2.53-2.55" (mag bodies vary from part to part).
The modification is pretty simple.
1) Pull the guts from the AW mag.
2) Slide a paperclip or toothpick in between the spring and follower to wedge the spring away from the bottom side of the follower. This is to allow clearance for a band saw blade to avoid the spring.
3) Measure 0.37 - 0.39" and trim that much off the back edge of the follower to make room for the spacer. Take care not to hurt the spring.
4) Insert/wedge the spacer so that the channel in it is facing towards the front of the mag with the cutout for the spring and bolt facing "up"

At first with most unicorn sightings you think this can't be real or it won't work. Well thats how i was, when I was told this inexpensive part will turn my AX rifle into a Unicorn i was blown away. I received them, followed the very simple instructions on trimming my follower and snapped it in the mag. HOLY HELL IT WORKED !!!! My rifle instantly started to glow and I could hear a gregorian chant in the background. I placed several of the 6Dasher dummy rounds on the follower and inserted the mag. I could hear the chant growing louder and the glow became blinding. I proceeded to close the bolt and I was blinded by the awesomeness, it worked. The Dasher, BR & BRX with 105 & 110 all fed reliably from the rifle being level to full cant that the atlas would allow, even under very slow feed. Great product, fast shipping and very well thought out design. Buy them with confidence.
Good product! Had to sand down the sides a small amount for them to fit in the mag but I would rather them come oversized than under. Ran several rounds through them with zero flaws. I would definitely recommend them.
