M16 MODEL 601 LOWER RECEIVER PIVOT PIN Reviews & Ratings

MODEL 601 FRONT PIN ASSEMBLY

The Brownells M16 Model 601 Pivot Pin serves two purposes in your retro M16 / AR-15 build. First, the button has the correct contour to give your rifle an extra level of detail accuracy. Second, and more important, this M16 Model 601 Pivot Pin must be used on the Brownells M16 BRN-601 retro lower receiver. The reason? Our lower so accurately replicates the original Model 601 receiver so closely that it does not have the modern magazine fence to allow use of a modern AR-15 detent spring and pin.

Machined from hardened 4130 carbon steel
Period-correct matte black (dark gray) phosphate Parkerized finish
Long-wearing hardened stainless steel detent ball included
Required pivot pin for use on BRN-601 Lower Receiver (#078-000-359)

The Brownells M16 Model 601 Pivot Pin plays a small but very necessary part in helping you build the finest retro M16 replica possible.

A specific pin for a specific job

This pin was designed to specifically fit Brownells early model 601 designed Retro AR receivers. The only drawback to thing is it fits one (& as far as I am aware, because I'm not an expert on AR rifles) and only the one type of receiver; the BRN-601 and the BRN-PROTO. I do not know about the BRN-601 but if you order the BRN-PROTO receiver: you must order seperately the 601 takedown pin as it is not included in the BRN-PROTO ordering. (this is an oversight on Brownells part, I believe; it should be included. Add 10.00 to 15.00 to the PROTO's price point and include the pin Brownells!! Without it , nothing can be assembled until this pin is obtained. Roll of the dice if it is "Out of Stock" or not!!! Also, $15.99 for a single pin?!? Seems a little excessive. However, it is not my place to set Brownells prices. I am a regular customer of Brownells' (many thousands of dollars in the last 4 years; look it up Brownells. I'm not exaggerating)(customer #06134972) and for the most part I'm pleased w/ Brownells (99.44/100ths% pleased) BUT! This pin is one of those things that misses the mark in customer satisifaction. Not the design, function and workmanship as that is spot on. Its how it is offered to your customers. You have a part that will not function without it but it is not included as part of the receiver. The customer is left to 'reading the fine print' to discover that the pin is critical and needs ordering to make everything work. You missed the mark in customer satisfaction on this part offering Brownells!
