I've just hit the 3k mark in rounds on my Olympic PPFT-M4SS, and without any failures I have to say I continue to be impressed. I've shot near exclusively xm197 and xm855 through it with one 20 round box of some Hornady V-Max 55 gr, and it hasn't failed once. Got sub MOA groups this weekend with some xm855, and that's on a non free float rail using a grip-pod. For the low price point of this model, it's hard to say it wasn't worth it even with the overall poor reputation of years past Olympic models. Excited to see what it'll do with a single stage match trigger in it!
