    I had a Rock River carbine before, it was a very nice rifle. It never hiccuped on me, I wouldnt worry too much.

    In all seriousness, do you know if that BCM bolt upgrade kit (the one I linked to) would be allowed on your duty rifle? Quality gas rings, Quality milspec extractor, quality extractor spring + insert etc...those are all very high wear parts. Most failures associated with the bolt/BCG are going to be traced back to those parts. I have several of the bcm bolt rebuild kits stored away. Great to have around. Let us know how everything goes.

    I am curious to see if Quantico has done anything to them. I doubt we'll be able to do anything to them here in the field. I got repremanded a while back for simply putting a plug in that gap in the bottom of the grip on my Glock.

    Interestingly, spoke to one of my buddies at HRT and he was issued one as well, he's run it for 3+ yrs now; it has a giesele trigger set, and troy battle rail w/10" upper. Also a chrome bolt and barrel. He also said it was "slightly modified". Although I noticed a HK416 in his equipment room and when I asked which sees more use he just grinned.

Because calling it 'training to stop a rioting, starving, panicking, desperate mob after a complete governmental financial collapse apocalypse' is just too wordy." or in light of current events: "training to stop a rioting, looting, molotov cocktail throwing, skinny jeans wearing, uneducated bunch of lemmings duped by, or working directly for, a marxist organization attempting to tear down America while hiding behind a race-based name"

    This makes me laugh. I have no idea where the LE love for RRA comes from besides dirt cheap. I have never been satisfied with the quality of them. If only LE agencies bought cheap upgrades we'd all be safer. We have old 70s era Colts with no rifling in the barrel and rusty bcgs. COME ON NEW POLICY, COME ON!

    My SWAT team has 4 RR 10.5 rifles, each with probably 8-9,000 rounds on them. No issues.

    Had a RR CAR Elite a long while ago that chewed up anything it was fed and spit some of them out in the sub MOA fashion. Only issue it ever had was the ss match trigger went soft and began to do scary things...

    Well, they're here and I finally had a chance to look at a couple of them today. They're RRA, LAR15 in 5.56, 14.5" barrel, fixed front sight post, quadrail, safe/semi selector, M4 basic collapsible stock, and Eotechs. Pretty much what I was expecting. After getting a couple of them apart, it's pretty much what I saw in the links you guys posted ( https://www.m4carbine.net/showthread...w-better!-quot ).

    Gas key is sorta' staked, buffer tube is not. Oh and there are a couple of Troy magazines floating around in the gun cases. Not familiar with these at all, only have Magpul for my personal boom stick.

    Best part of the whole deal should be the issued ammo, green tip for training and the FBI duty rounds (whichever one we're using now, sadly I don't even know). Have seen a couple different 5.56 offerings recently during training days, mixed in with the loose green tip.

    Another member and myself looked at some RRA carbines last year in GA in one of my classes. They were all FUBAR, gas ports were HUGE among other things. Bottom line is that I would check them, fix any shortcomings like stakings and then do the best you can.

    I'm anxious to take 'em out and put some rounds downrange. Typical training day might be 5 or 600 rounds and I'd feel good to get through that with no stoppages or malfunctions just to start out on the right foot I guess.

    So these are not LE "Select Fire" M4's? and are just AR-15's?

    I think LE price on a real "Select Fire" Colt M4 is only $1200.00 How much cheaper are these RRA's and why didn't your agency go with real M4's for duty use?
    Right or wrong, black or white. Cross that line, your gonna pay, but in the dawn before the light, we live or die by shades of gray.
