Great review. We really appreciate your input on these forums sir.
I bought a JDI 551, with a 16” barrel. I first laid eyes on a Sig 550/PE 90 as a boy back in the early 1990s and always wanted one. I have to say while it is an incredibly accurate rifle using diopter sights, it does not hold a candle to the AR-15 platform in terms of usability and function if one had to carry it for duty or war.
I put a B&T handguard on mine, and the trigger is far better with the Shooting Sight trigger and hammer. However, the rubber dust cover that is riveted in place, lack of a threaded barrel (at least on the ones imported here), the known issues shooting 69-77 gr SMKs (extractors breaking) leaves much to be desired.
Having said, I like mine. I got my “fetish” out of my system now. I will be keeping it until the day I expire for certain.
