Great LH BCG – BCG functions flawlessly on the LH AR I put together for my wife, super happy with the fit & finish as well as the fast shipping!
NiB BCG – The NiB BCG if absolutely outstanding. I’ve shot very close to 500 rounds with it and it hasn’t missed a lick! No mis-fires……nada! I’m planning to purchase another one for my second AR-15. Also, the shipping was super cool……………received the BCG withing five days after order placed! One competitor but I won’t mention their name (located in Tacoma WA) takes three weeks ju8st to start their shipping process!!
Left Hand Nickel Boron BCG M16 / Ar15 Bolt Carrier Group
First purchase – I ordered a left handed 5.56 bcg and charging handle. The bolt came in right handed. I called them about the order and they sent me the correct one in 2 days. Also they sent an envelope pre addressed to send the wrong one back. Great customer service and timeliness. Couldn’t ask for anything better. Just an honest mistake. I will buy again.
Excellent quality, price & customer service – The quality is outstanding, as is the price. If I need another BCG, I will be ordering from Mid State. Also, excellent customer service. The guys were quick with answering questions on my first purchase of a left handed AR upper receiver & BCG.
