SIG 551A1 Reconfigure

As promised on video, I will be running the SIG 551A1 rifle for the rest of the summer. As such, it needs a few upgrades and changes: Primarily a red dot and better safety selector. 

For those wondering, the drum rear is hot garbage. In my opinion anyway. Others will differ. Yes, it works. Yes, I can make it work, as seen on video. But it’s still a turd. Especially when the drum decides on it’s own to change from it’s expected setting. Frustrating.

Rear drum on SIG 551A1 removed. Showing BUIS underneath.

So off it went. And what do we know? There is a hidden BUIS underneath! I think that is VERY cool! Also probably more usable! 

Selector switch. Simply stated, the factory OEM part is too short. But…what do I mean by that? Too short for whom? The answer is…most people. If you happen to have largish hands like I do, then yes, folks like us can manipulate the trigger without breaking our grip. But even then…the stubby OEM selector is trying to stab the pad of my thumb with every iteration. 

Not a big deal working it dry on the showroom floor. On the range putting in reps over and over? Get’s a little taxing on the digits. Unnecessarily so. Off it went, to be replaced with a Krebs aftermarket selector. 

Special note about the RDS setup in these pictures. First, I removed the front sight entirely since the hood format occludes too much field of view by modern shooting standards.

Front sight removed.

Second, I haven’t decided if I will keep the magnifier on the rifle. Why? The gun is already borderline porky. And with the RDS + magnifier, you really start to notice the weight.

Not that big of a deal, but we haven’t even put a light on it yet. Which tells me there are no two ways about it: The SIG 551A1 is going to be a porker.
