What a most needed up garade or in my situation it helped my AR run like the oiled machine its always had before I stared to have problems cycling and the extra ones are great to have on handle . thank you
Excellent product and fast shipping !!
Good quality kit easy to install and actually got my order before I received an order from another company placed at the same time that is only a couple hundred miles away from where I live. Have never had an issue ordering from BCM in either shipping or quality of what I order.
Although I love the AR, it's extractor design is weak and the standard 3 coil springs just don't make it. Upgrade to this 5 coil chrome silicone spring with o-ring and extractor insert. Very inexpensive way to enhance the reliability of your weapon.
Perfect fit, arrived quickly and excellent quality.

Adding this spring upgrade was like adding jet fuel to a bad ass muscle car! Got my kick ass American power back! Thanks BCM!
Love you extractor upgrade kit. I have one on my 7.62x39 and now on my 450 bushmaster. Both have helped greatly. Bought two more for back up and extra parts to have.
BLUF. This with the H-3 buffer solved my .300AAC cycling issues. Super/sub 125-220GR, suppressed /unsuppressed. Not one issue after 600+ rounds and counting.
