I was just wondering how much weight is saved, if any, on a rifle length MRP 16" chrome lined upper vs another upper built with a standard forged upper receiver, 16" barrel with the same profile as the MRP, and a 12" Larue rail?
My thought is that the MRP would be slightly lighter but I could be wrong.
Also, are the MRP chrome lined barrels considered to have a mid weight or HB profile?
I don’t have a MRP but I would think that the MRP setup as described would be slightly heavier than a standard upper and rail due to the extra forging around the barrel nut on the MRP. But I could be wrong.
I have been toying with the idea of using a MRP as the basis for a SBR build but I can’t get over the fact that I have to use LMT’s MRP barrels. I know that LMT 10.5" CL barrels are very good according to numerous reviews but I can’t help it.
I’d say the MRP would be very slightly heavier than a similar LaRue type upper with similar barrels.
I don’t have a 16" CL barrel, just the SS one, but it’s pretty much a medium contour. The 18" must be HBAR heavy, mine weighs a ton.
If you can, get the 16" 1/7 SS barrel, mine has been one of the most accurate barrels I have ever owned, and with a variety of ammo, 55gr through 77gr.
16" below
The MRP is the perfect SBR, and the 10.5" barrel is a jewel, no need for SS on a SBR, just a suppressor.
I remember seeing that LMT ad where they mentioned using 13 parts less than a conventional upper. I figured this would be a slight weight savings but I guess I was wrong.
Thanks for the info guys!
A Carbine LMT MRP has a 7" rail. The ones I see here are rifle length barrels/ rails, and we may not be comparing Apples to Apples.
I can’t defineable answer your question, but wanted to point this out.
Here’s a Pic of Mine:
Fixed it. It will be slightly heavier.
