JR,I mined a lot of information on this forum a while back when putting together my 416 & UMP45 but never posted any pictures.
Put a bunch of rounds through the 416 in recent months battling feral hogs - it has run flawless. Both are Form 1'd with a Surefire SOCOM556 and a Gemtech-45.
I'd be curious to see a picture. I know you can buy one without markings, but I didn't realize some of them had a serial number on the inside lip.hello, I am new to the forum and just purchased a 416 upper and a brownells lower and plan on doing a 416 build. I have a few questions about my upper receiver and wanted to know if it would be possible to have an expert help identify it. This seemed a good place to start. My upper is comprised of an AHB4 slim profile barrel 10.4 inches with a non vented gas block. The bolt is date code AE but my upper receiver has no proof marks on date codes on the left side, but it does have a lower digit serial number on the bottom. I can provide pics if necessary. Thank you! I tried contacting HK for help and they told me they couldn't disclose any info.
