As many here know, I am too analytical about everything, not just this rifle platform.....and I have come across something that has me stumped.....The proper way for the op rod guide to be installed.
I have read much and installed many, but most were used and the lip already worn off....some say the raised lip should go rearward, some say forward....I guess this question is truly for the bonafide armorers such as Art , Gus, Jon, etc. etc. etc.....alphabetical order on purpose GI1
I received an op rod guide... N.O.S. in the wrap, and it has a raised lip on one side of the op rod channel hole. The lip is smooth and the stepdown machining is rough, visibly rough.
My question...which way does the op rod guide go, with the lip toward the front , or toward the back of the rifle ?
As stated, I read alot and thought alot...I thought which way would lend more support to the op rod, keeping it aligned and supported throughout its travel cycle....which side at the moment of explosion would receive the most stress or strain,...seems like the front would..... would the return action of the spring be reason enough to face it to the rear to allow for variances in the op rod receiver channel ?....Finally, I gave up and said....why not ask someone that knows?
