Review
Bought these to replace the old tired and worn springs in my magazines. These springs are what all magazines should come with from the factory. No worries about storing loaded magazines with these springs. Easy install. Blazing fast shipping.
I received a pack of 3 of these springs very promptly, within 3 days. They are high quality at a very reasonable price!
Replaced my factory mag spring with this hd spring and fixed problem immediately. Great product. Thanks.
Once I opened the package I knew these springs were a game changer. It was a simple swap and I have the confidence that my ammo will feed each and every time I pull the trigger
A great spring at a great price with super fast shipping at a time when NOBODY else comes close! Buy lots of them!
Order arrived on time and the new springs replaced the old ones no problem
The springs have the same number of coils as the OEM Magpul and Lancer springs for the 30 rd mags, but they weight 10% more (22 vs 20 grams), thus, assuming similar steel being used, they should be 10% stronger. I took one star off because while the springs fit the Magpul mags just fine, I did have to bend the top coil a little bit to get it snap into the Lancer mag followers so that it sat flat. Also, the top coil's shape was not consistent across all springs -- some required more or slightly different bending to fit the Lancer mag followers properly.
I used these springs to replace the original magazine springs that came with my ASC mags. Installation was easy, spring tension was stiffer (as advertised) and they exhibited extra pressure, ensuring each round was quickly and properly presented for the bolt. High Quality Parts from a High Quality Company.
Speedy delivery which I liked. Product was as described. Good tension on fallower. Have not shot it yet, but they feel much better than the factory spring's.
Just comparison from standard springs removed from my various magazines alone, these are well and sturdy. Loading is a bit more rigid but that’s what a speed loader is for. And they cycle well. Will pick more up when I get some more mags.
Doing business here is fantastic. Great product at a solid price. Fast shipping without gouging the customer. They have my future business for sure!
Was having multiple "failure to feed" issues when shooting "rapid fire". Changed to the "extra-power" springs and solved the problem. The springs made the magazine function without any misfeeds.
I put two new extra power springs on two failing mags and bingo they became the best mags I own. This is the short story but I not kidding. I put these new springs/mags through, low quality ammo, different cadences of firing, rapid mag dump at the end. They worked great. I am going to be buying more for the other 30 round mags I bought when they were legal.
Great replacement spring for magazine rebuild, fast shipping & veteran owned. Winner winner
My product arrived much sooner than expected especially with Covid-19, excellently packed with sticker as a nice bonus. This is now my go-to company for gun parts, the customer service is phenomenal, love this company thank you everyone at MCARBO!!
Bought the 3 pack and they arrived fast as lightning. Top quality springs. Thanks!!!
