Thing is a freaking jack-hammer ! Lube it up per instructions, feed it good ammo and smile ! Extremely accurate , surprising actually for a 7” barrel. Big fan of FM and Rainer arms .
Review by Curt S. on 18 Aug 2021review stating Good upper great price
I'm going to preface this with the fact that in my infinite wisdom I did not read the giant letters and the top question saying that this is only for glock lowers/mags. Woops.
Anywho, despite that I genuinely like the upper. I like the front side charger, although it can be a bit awkward locking the bolt back.

After reaching out to both Rainier Arms and Foxtrot Mike I heard back from Foxtrot first and they sent me a replacement comp immediately. They were fantastic, I only with that if there is a design change/revision that the images are updated to reflect that. I’ll be hanging onto it now.

I’m sure that this is a fine product, however 90% of why I bought it was the big flash compensator. It arrived very quickly and after putting off ordering it for so long I was quite excited to open it, however my heart dropped when I saw it. That big end that reminded me of old submachine guns that I’d been drooling over was only half the diameter...Read MoreRead more about I’m sure that this is a fine product,

Q: It looks like the muzzle device that comes installed is recessed into the hand guard. Is it removable and is there enough clearance to run a suppressor?

A: It can be removed however because of the side charger and narrow handguard suppressor fitment is not guaranteed with all suppressor options.

Q: Will this work with lowers that use colt mags?

A: This upper is designed solely with glock magazines so we cannot guarantee that any other magazines will function.

Q: Can you add a dust flap onto this ? Also will this fit a palmetto state armory AR9 lower ?
Rainier Arms

A: It is not setup to take a dust cover. Compatibility with PSA lowers is not something we can guarantee.
