I have a question about Larue uppers???

[DD977GM2]

On the website it says there are NO M4 feedramps in their Stealth upper receiver. (http://www.laruetactical.com/stealth-billet-upper-lt007-a3)
I have only owned uppers with M4 feedramps.
Anyone know the reliability of having no feed rmaps?

When I save up enough cash to purchase one, always have wanted the DMR-16 upper (http://www.laruetactical.com/larue-tactical-dmr-16-upper). :D
So basically the upper receiver on this sweet little gem has no feedramps
and I am just a bit concerned of the feeding issues that could present itself
from shooting it, even though after every range trip, I clean my firearms
very well and clean just 1 firearm a day to ensure I dont get complacent while cleaning.

Appreciate any insight from folks who ACTUALLY have owned a larue upper or complete Larue rifle.

Mid length and rifle length gas AR's don't really benefit from them. IMO 16" carbine gas AR's can make due without as well.

I have a Stealth upper. Never had a failure.

I have a Stealth upper. Never had a failure.

Ditto on that and on my DMR upper as well.

You wont have a problem with LaRue. All of mine are bad ass and no failures. Save up for a complete rifle. The fit and finish is amazing.

Only 1 of my ar platforms has M4 feed ramps, never an issue.. Until they were offered to the public civilians got along just fine w/out them. Same for red dots and other "new fangled" creations.
