Geissele Super Duty Lower Poor Machining Update
This is an update to a thread I made over the weekend. I noted that the machining on the inside of the magwell of a receiver I just bought on Primary Arms was very shoddy. The thread was locked due to the comments becoming personal attacks. I ended up deleting the post because I thought it would be better to give Geissele a chance to complete the customer service process. Geissele has completed its review and determined the shoddy machining is within their acceptable tolerances.
This is a note for people who may be buying lowers that care about paying top dollar for quality machining. The first set of pictures is the lower I just bought. You can see the milling tracks on almost the entire inside magazine well. There is a noticeable amount of removed material in a wavy pattern. I went and looked at some other receivers I have access to for comparison including two Colts, a Geissele GFR, a Hodge, and a SOLGW MK1. None of them look this bad. I’m sure the Geissele will function as intended, but when a company charges a premium for quality and doesn’t deliver, people should be able to make an informed decision if that is where they want to spend their hard earned money.
