    "...those that don't know or don't care."

    That is what I mean - a statement that everyone who does not own a [insert flavor of the month] is ignorant or apathetic. You don't know anything about me, no offense, nor how many rifles I have built, my skills (or lack thereof) with a lathe and mill. etc.

    I don't own a Bushmaster; maybe you have built more rifles than I have built, and most of my builds are bolt action. But I have used recent Bushmaster barrels on AR builds, and they work fine for their intended purpose. I respectfully object to the implication that I don't know nor care about quality just because I disagree with you.

    Buy the barrel, not the brand.

    1. If you have a magazine with anti-tilt followers, M4 barrel extension and M4 cuts in the receiver are not needed.

    2. If you don't shoot ammo above 55gr , neither anti-tilt followers or M4 feed ramps are needed.

    Perhaps. My highest use gun has no M4 feedramps, but I indeed never shoot anything heavier than M855.

    I never had issues before the anti tilt followers invaded my mags, but I was pretty religeous about keeping fresh mags in the rotation.

    First let me say that if BM barrels work for you, then that is all that matters.

    The second biggest problem area on the BM AR is their barrels. They are not mil-spec steel, are not HPT and are batch MP'd. Their chamber's can vary between .223 and 5.56 and have a GP that is way too large (and out of spec).

    62gr ammo is the start of ammo that can cause an issue. Typically though, something in the 64gr (soft points) and above are where you CAN see a problem (as the bullets are much longer).

    I added the part in red. My own experience, with BMs without the ramps in fact, is that M4 feedramps help in feeding soft-point ammunition.

    Agree. Soft point's and none M4 cuts generally do not play well together.

    You know what else jams up in them, sometimes even worse, is the various polymer tip ammo.

    I hear people say all the time "well I don't shoot that stuff". Great, then don't worry about it, but I have cases of both sitting around from times when it was all I could buy, and it may be one day that it's all I can buy, or load, again.

    I understand when people say they don't care about having them, but M4 ramps are one case where I see zero downside to having them.

    This is always my case for M4 feed ramps. You never know when you will have to borrow ammo that is soft point/polymer tip.

    Why do these types of threads turn into "you're an elitist" or Bushmaster is just as good, blah, blah, blah. I personally get sick of it.

    No they are not just as good. It would be real simple for them to pull their head out of their 4th point of contact and just make their stuff the right way.

    Even if they are using ramps now, why did it take so long to catch up with the others who know and recognize the need?

    Why do they insist on using 1/9 twist and not doing individual HP/MPI testing of their barrels and bolts?

    No one in the know ever said RRA or CMMG was the rage. Those that did were idiots who where misinformed and generally don't know what they are talking about.

    Right now IMHO the top brands are (no certain order) Noveske, BCM, LMT, Daniel Defense and S&W. Speaking of S&W they came into the game much later than Bushamster and they produce a rifle/ carbine that is much better. And they have been more responsive to the shooting public.

    You may be right about that! My '90's BM served me well. But it was a big fat heavy barrel so I unloaded it. The one I referenced with the M4 ramps sees little use but has been ok for that little use.

    Funny thing . . . may be significant . . . may be not, but when I move my TA33 from my N4 carbine to my N4 Recce, it takes about 5 clicks elevation to re-zero with the other. That ain't much. When moved to the Bushmaster, it take 55 clicks just in elevation! Surely that means sumfin.
