(downloadable PDF)

Hold the loader in your left hand, and press the adapter lock with your thumb. With your right hand, hook the Mag Adapter into the top of the Lightnin' Grip Loader and swing the bottom into the slot. Take your thumb off of the lock button. it should pop out to the locked position when the adapter is in fully seated.

Insert your magazine into the adapter until it latches into notch.

To remove the magazine, while holding like pictured here, gently press down on latch and pull out.


1.) Slide open the Bullet Reservoir Cover and drop in up to (50) 22LR cartridges.

2.) Close cover. Gently shake the Lightnin' Grip Loader, keeping it level and
the reservoir cover on top.

3.) Raise the reservoir end to slide the cartridges in to the Loading Channel.

4.) Repeat #2 and #3 until the Loading Channel fills sufficiently.


5.) Raise the reservoir end and smoothly squeeze the trigger to load a round
into the magazine. The trigger needs to return to the nearly out position to
seat the round and stage another bullet for loading. It is usually a good idea
to count the bullets going in to know when to stop. It is possible to force in an
extra round.

NOTE: Quickly snapping the trigger in can cause the bullets to bounce in some
magazines and "hook" the rims in the wrong direction making them hard to get out.
Sometimes a hard rap on the bottom of the magazine with your palm or on a book
will bounce the bullets to unhook them.


Some 22LR cartridges are real sticky with wax lube. After filling the reservoir, give
them a shot of Remington (Rem Oil) Teflon Spray Lube. Only a small amount is

CAUTION: the unit is molded from Lexan, and some lubes will attach it.

Not all magazines fit the same; you may need to apply a little seating pressure
against the magazine as you are loading it. As Pictured here.

5 of 5 Saved my fingers March 8, 2021
Reviewer: Christian Tan from Tucson, AZ United States  
The loader and adapter work exactly as described.  All I had to do was load the ammo, shake them into place, lock in the mag, and squeeze away.  The loader will fill all 25 rounds without problem; you'll need to count how many rounds you load into the mag.  If you try to load a 26th round, the loader may jam.

5 of 5 Works Great! February 12, 2019
Reviewer: Kevin B from Lockport, IL United States  
This works great for the M&P 15-22 mags. Loaded my 25 round mags about 5 times each today and it only took seconds to load each mag. Attachment works great.

5 of 5 Yea!!! It did work with Browning BPR ammo July 8, 2018
Reviewer: Doug Caldwell from Plano, TX United States  
I have loaded three mags twice with the suspect ammo and it worked great. I was willing to switch if necessary to Federal or Winchester brands if it didn't it.

5 of 5 This works!! March 4, 2018
Reviewer: Doug Turner from Manchester, NJ United States  
I used to hate shooting the 15-22 because loading the mags was a pain. I now shoot so much .22lr that its getting expensive. This puts the fun back into shooting the 15-22. I tell everyone that I know who has a 15-22 where to get one!!!
