Parkerizing Rear Sight

I am thinking of parkerizing my USGI rear sight. I have done it before on a Garand with good success and have done pistols too, so I have the experience. However, I have never done a rear sight Garand or otherwise. I've searched quite a bit, but can't find an answer - how far down does the rear sight have to be stripped for parkerizing? I mean do the knobs have to be stripped down to their components beforehand, or can it be done as an assembly? Thanks in advance.

I have always removed/disassembled the main components of the rear sight [I do not take the knobs down to components] but do the elevation and windage separately. I like to be sure everything is blasted individually, and properly prepped to ensure nice deep parkerized finish.

I believe taking your rear sight apart [in it's main parts] will provide a much better end result. Like any refinish project [stock, parkerizing etc.]. Prep work and how well you prepare the parts is "The Most" important thing. If you cut corners your end result will reflect that!

M1A. Sorry, I didnt mean to imply parking the rear sight as an entire assembly, but whether or not the knob 'assemblies' themselves should be broken down into components. Sounds like you do not do that.

Is there a huge contrast with the finish of the knobs compared to the receiver ?

Thanks from JMQ4

TB:

Somewhat, for this particular rifle, darker USGI park against a light Polytech.

I like the darker finish myself. If you have done it before , why not just repark the complete action ..that is one way to match the finish and sights etc.

Figure the windage and elevation knobs could hold oil/grease internally, so blast them liberally with brake cleaner first. At that point you should be good to go. I normally sandblast everything before parkerizing but the chance of getting grit inside the knobs would stop me from doing that. I have prepped stuff that didn't get sandblasted by dipping in Jasco Prep-N-Prime to remove bluing or black oxide finish before park.

As was mentioned earlier, by not completely disassembling something you are going to park, you risk contamination of your park solution. I've not done an m14 rear sight, buy I've done a good bit of parking over the years, and have never left anything assembled. Even a welded in AK bolt rail will hold some grease that finds its way into the solution. But the rear sight is so small you could do it in a small container with minimal sacrificial park solution. Just a thought.....

Chief, thanks for the reply. I know about the special tools, that, unfortunately, I don't own. That's why I was asking - just curious if someone had a positive experience with parking the assemblies.

I can't even begin to tell you how many rear sights I've reparked, let's just say a whole bunch. I wrap the pinion of the elevation knob in duct tape nice and tight and blast just the knob. Any sand that gets in there comes out when I prewash it in running warm/hot water before put it into Parkerizing solution. You need to get any sand dust off the part or the dust parks but not the metal underneath it. Just turn the knob as your running it under the water. I have a wooden block that goes across the tank I put the pinion shaft into so just the knob is in the Parkerizing.

Thanks from CHARLIED308 and JMQ4
