Hey guys,
I've got another question that may seem out there, but here it goes.
On my A3/A4 Flat Top Receiver I have a detachable carry handle. I usually do not remove it because I have no optics as of yet. I removed it the other day and discovered that the ends of the steel clamp on the handle had dug a little into the aluminum of the upper receiver. See the photos below.
Now I'm okay with marks from usage, it's going to happen eventually. However, I am concerned about possible reaction over time of the dissimilar metals touching. Specifically from the bare aluminum touching the metal of the carry handle clamp. I've read about galvanic corrision from dissimilar metals, especially in regards to the barrel nut and upper receiver. That subject prompted me to wonder if my situation should be of any concern.
I'm guessing I may be letting my OCD run wild again, but I'd like to hear from some of you with long time experience with the AR15 platform.
Is galvanic corrosion even a possiblity here at all ?
Thank you for taking your time to read this and to any responses.
