BCM® SOPMOD Bolt Upgrade/Rebuild Kit

I can not say enough about this kit. I was having ejection issues. This kit ejects the cartridge with ease. The spring is completely different as far as quality, compared to what my bolt originally camw with.

Before the rounds got stuck cause the expansion pressure in the chamber. Now it pulls every brass or steel round out of the chamber. Best upgrade, it works 100%.

Used this to rebuild a M&P15 Bolt that was have ejection issues. Fixed the problem immediately.
Shipping was fast.

Wow!I was a bit skeptical on whether or not it would work.
After put things together, (just to mention the spring was a little bigger than the original and I had to press with players the whole thing down, to put the pin but, no more than 5 mins.) Next day, I headed for the range and I was very surprise that, the extractor kit performed like a champ! The BCG when back and forth, the casings out around 2 and 3 (clock) for more than three hundred rounds of Wolf brass, 223 55 grains. The quality of those little pieces are outstanding.
Bravo!!!! Bravo (pun intended) you have a happy costumer here!!!

these were ordered as spare parts, for my BCM upper or friends guns that need upgrades.

Fast and efficient service, and all products arrived quickly. Very happy with purchase and service, now just need to finish upgrade and try it out.

Great price and Quality Parts I will continue to buy this item and even have backups. Fast shipping and even great customer service you won't make a mistake purchasing this item

Fixed the double feed issues and failure to eject

I haven't used the springs, or spare parts; I bought them for when the parts on my ARs wear out. It was painless to select the kit that had the parts I wanted, and buy them.
