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.

Magazine inserts at an angle into the adapter. Latch is tight. Need to push latch in with thumb.

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 Using AR15 adapter for HK416 magazines October 22, 2021
Reviewer: Michael Botwin from Fresno, CA United States  
Followed the instructions and removed some of the loader wall until it fit the HK416 magazines.  Used a Dremel tool and slowly ground down the plastic.  Works great!  Functions just as well as my dedicated S&W model 41 and MP15-22 adapters.

Love my. Lightning loader!

1 of 5 Wont stay October 15, 2021
Reviewer: Casey Heckenlaible from Attica, IN United States  
Received this with my speed loader that was already "modified" my mags will not stay clipped to it and the slightest wiggle they release making it so when you are squeezing the trigger it just shoves the mag off.
