Delivery took 3 days! I live across the country. Ordered last Friday 03/27/20 got it Tuesday following with a confirmation email every step of the way! Everywhere else is taking 10-12 weeks!
I ordered a pack of 10 springs on a Thursday night, they arrived the following Tuesday morning. They seem very sturdy yet, once installed, it remained easy to load the mags. I would recommend this company and it’s products.
I ordered a 10 pack of AR15 springs. I actually got them a couple of days before expected. which was an AWESOME surprise! Haven't added them to my mags yet, but these springs look like they will do exactly what they are supposed to.. Plus I got a super SWEET "M*Carbo" sticker to slap on my ammo cases! OOHRA!
Ordered on a Saturday night, shipped Monday morning, received on a Wednesday and would have been sooner if the weather had cooperated. Springs worked great and were simple to install.
Most of us who own PLR16’s know they commonly have feed and eject issues. Changing out the magazine springs eliminated all feed frustrations I was having. Thanks Mcarbo!!
My 50 beowulf magazine kept jamming, I replaced the spring with these and they are now flawless. great product, easy install.
Chris is by far one of the best owners to make the effort in being involved with clientele. The company provides excellent products and are just as advertised. This place is highly recommended. Springs are excellent quality and make all the difference in mag performance.
These replaced standard springs that were used and abused. They were immediately tested on range day and there were no problems. Rounds and followers ran as needed under aggressive use. More magazines will soon receive the same upgrade.
Got a few HK steel mags that wont lock bolt to rear after I have upgraded my AR to different gas tube length and HEAVY buffer. HK springs are notorious but that certainly don’t warrant to be thrown away. The MCARBRO springs are about 2 inches longer with wider gauge and noticeably stiffer. The HK springs are coil in a tighter pattern in order to fit the bottom plate and follower. With that said the MCARBRO spring barely holds the bottom plate and did not fit into the follower. The bottom plate has 3 retention slots and the MCARBRO springs could only hold 2 of them, and they are too fat to even fit inside the follower. BUT, once you have everything put back together, these MCARBRO springs behave VERY MUCH like the original HK spring except the MUCH stronger rebound. Which completely fixed my issue. Even though they don’t fix prefect, they do perform beautifully! I am not sure about the longevity but they certainly work for now.
Havent used these yet but the shipping turnaround, tracking and follow up was excellent.
Ordered these springs to correct a FTF issue with magazines. problem seems to be corrected. Purchased (2) 3packs good price, and now I have a couple extras. Would buy again. Would recommend to like minded individuals.
Just as described. No issues in a few replacing worn springs. Fit in numerous makes from g.i. magpul, and hex. Would recommend.
Very fast shipping. Easy install. Great follow-up communication after the purchase.
I couldn't be happier with the whole deal. The price was reasonable; the springs installed w/o any issues (and seemed to fix my intermittent FTF problem with 6.5 Grendel mags) and the customer service/shipping was excellent.
Great to replace old tired springs
Bought 25 of these and have only used one so far. No issues and it's a great item to have on hand
