Question: Is this speed loader made because it is illegal to transport loaded magazines while on your way to the range?
Document: Butler Creek makes a wide range of loaders for rifle and pistol magazines. All of them work well and make loading magazines easy and painless. This one for the AR-15 magazine is no exception. If you can throw a light switch you can use this loader. I just loaded three 30-round Magpul magazines in almost less time than it took to open the boxes of ammo for them. I like the way the lever can be pushed down into the loader for compact storage.
GUYS these are the best thing since white bread. This has to be the easiest Magazine speed loader that was ever made. I recently loaded and unloaded 7(seven) MAGPUL 30 round magazines in under 10 minutes. It actually took more time to reach into my ammo box and pickup a 5.56 cartridge to feed the loader than it was to fill the Magazine.
This expedites the way you can load different ammo into a magazine, if the user desires.CONSTRUCTIONSturdy polymer and will last the user for years, if not abused. The loading lever can be depressed into the housing of the loader and makes for a more efficient use of the range bag.CONCLUSIONThis is one of the best tools of the trade for loading up your AR-15 magazines. I also have the universal pistol magazine speed loader, too. It is just as useful.I highly recommend it.
The speed loader locks right into the same port used by your rifles mag release and with no effort magazines can be loaded and unloaded. I have been using this speed loader for several weeks now and even thought it is platic it is holding up very well. Great for bulk shooters and lazy people. Its light weight construction and small size makes it great for transporting and range bag storage. THIS IS A MUST BUY PRODUCT!
I recently purchased my first AR15 223. When I loaded the magazine the first time it was very difficult and hard on the thumb. The Lula speed loader made loading and unloading simple and fast.
This is the only way to go when loading your magazines. Loads each round perfectly without the pressure on loading by hand, especially when you have the last few rounds to place in the mag. Have one for my pistols. Load fast and easy with the LULA speed loader.
This magazine loader is just TOO easy to use. I can load magazines way too easy and fast. This loader is one great piece of equipment. Every AR owner needs one in their range bag. You won't be disappointed.
Bought the .223/5.56 Lula loader and can summarize it this way: A great piece of engineering design and functional use for those who shoot large magazines and/or spend a lot of time on the firing range. This product does exactly what it promotes; in fact, I was amazed at how fast and efficient it works.
My loader came on time and in good condition. If you've loaded many AR mags by hand, you can really appreciate this handy little gem! The loader is super simple to use and quickly loads/unloads both metal and polymer magazines. The top lever retracts down into the housing for safe travel in a range bag or gun case without worry of damage which is an added bonus.This will NOT load/unload 7.62x39 AK mags.
Purchased the LULA magazine speed loader, and it's been great.Unless you've got lots of magazines, you don't want to spend valuable range time reloading them once you've run through them. The LULA speed loader allows you to reload your magazines in a blink, and you can get back to why you were at the range in the first place.
