Yes, it fits pretty much any hand guard that has 3 o'clock and 9 o'clock side rails (I heard Moe rail sections work on some 556xi hand guards?).
This is likey my check off list I just need the python $$$$ and the KSG. Nice collection.Took a new picture to include all of my collection.
Sig 556 SWAT Patrol, 1968 Colt Python, Sig P238, SigPro 2022, Benchmade Adamas Automatic, Kel-tec KSG, Sig 1911, 1994 Sig P226, and Sig P229.
I can understand that. One day I took out my SIG 552 to a 3-Gun match for grins and giggles. Several "pro" shooters were stunned by how well it performed and how accurate you could shoot from any position or distance. Now I'm interested in building or buying a true SIG 550. This video motivated me to start saving.Jealous! I'm saving up money for the real deal 551 but none on sale lol and going price is still 4500ish or more???
