HOLOSUN 407K/507K ADAPTER FOR – GLOCK MOS FITS 407K/507K

I was looking to sell my firearm. The guys there helped me find out what it was worth and gave me a fair offer.

Great place, Hard to find trustworthy people nowadays, very professional and knowledgeable! Will definitely buy from here again!

Had two transfers from Gunbroker thought 8th chamber armory. Each time there was consent communications and updates when the FFL was sent/received along with shipping updates and when it was received at 8th Chamber Armory. The personnel were quick and courteous with the transfer. Will definitely use them for future FFL transfers.

The staff at 8th Chamber were very helpful. I look forward to going back.
