They look good to me and I've heard great things not sure what else to say. Only time will really tell.
The BCM extractor revived a tired bolt for me and made my rifle function again. Very satisfied!
Great little upgrade. Takes 5 min and better than new.
I have upgraded my stag with your charging handle "ambi",ambi safety,bad lever,and now extractor upgrade and due to the excellence of your products am planning on complete bcg thanks guys for great products
A couple of my AR's developed inconsistent ejection. No failures to eject, just spraying brass inconsistently. Neither had the spring insert of the O-ring, so I thought I'd try the easiest fix first. Issue solved. This is a must upgrade if your extractor does not have either the spring insert of O-ring. Even if you don't need 3, buy the 3-pack. I saves a few bucks and you'll have a spare when you need it.
Replaced my extractor spring with the bcm extractor spring upgrade kit. Did not use the o ring that came with it. Solved my extraction issue with my 7.62x39 ar15. Easy installation and fast shipping.
Promppt delivery, OK price, they work, what is not like?
Great product, replaced all my bolts with the BCM upgrade kit. Could see and feel the difference on all the bolts during install and use.
Even on new none BCM bolts I would recommend the upgrade.
fairly sure the extractor spring buffer was a made to misplace item from an engineering standpoint. replaced the one I bounced off a few walls with a new BCM buffer. works well in a P.S.A. bolt with the P.S.A. extractor spring and P.S.A. o-ring. have NOT tried the BCM extractor spring yet though. can only vouch for the buffer.
