Very stout and tough to install on mine. Should work well, will tell after next range session.
I tried one of these out yesterday at a training class. It went on one of my Springfield Saints in .556. It was hard to install - I had to press hard because of the extra spring pressure just to re-install the pin - but I got it in, and it performed flawlessly! I stashed the other two sets in my BCM Gunfighter grip. Highly recommended.
Very consistent part and functions as designed. Very reliable. I trust BCM products. All my business with BCM has been great!!
Everything you need for a overhaul. Taller, stronger spring, fresh inserts, and O-rings. Outstanding!
Very well packaged and shipped as quick as could be expected during a Pandemic.
Quality product and very well pleased with the performance!!
Shipped fast. Great quality parts to keep as spares. You never know how valuable these are til you really need 'em.
Great product... No problems at all. Great shipping time..... Thanks
My original bolts extractor would not manually eject my rounds. I bought these and now I can eject them. Very good extractor springs, what else can I say.
I bought a custom made Aero precision M4E1 rifle and was having extractor issues. These springs fixed it right up! Now when I manually extract the round come clean out, and when I shoot I no longer get any stove pipe. If you have an AR-15-M4 style weapon, get this spring kit. You will not be disappointed!
