I sent a 14.5 inch MRP barrel to them to have a Smith Vortex pinned and welded. I got it back and the weld was horrible, you could still see part of the pin, my 10 year old probably could have done better I ended up having someone local redo the weld, ground and refinished it myself. It was years ago, I don't know if they're any better now, but I won't send anything to them. Like I said, you can't beat Marvin Pitts work. He has done 2 MRP barrels for me, one fully dimpled and refinished and the other, cut down, dimpled, refinished and pinnned and welded and they're phenomenal.

Edwin, since you posted the vintage ARMS ACOG mount, I'll post my 2004 vintage MRP, in continuous use since then, and has been the test bed for all prototypes since my old days at Battle Arms, it continues to serve that roll in my new company
Someone said this AR was thrown down the driveway lol. If they only knew.... the paint job is more than 10 years old, everything on this rig is well used, except for the SBCG prototype. Here in its 2004 configuration, still unpainted then, with all the then current technology

Awesome, Duffy.
You know, so many years ago, I painted my MRP 16" SS barrel with ceramic header paint ($2.95), then baked it on in the oven. Well I took a good look at it and noticed it now has a nick in it where the SS actually shows through. One nick! And it's been banged hard on everything, and is my best MRP barrel. I don't know if this makes any difference, but my heat treatment actually turned the barrel extension to a light gold color. Thousands of rounds later, it is still flawlessly accurate and shows almost zero throat wear. |

My rattle can paint job didn't fare nearly as well, I just figured I'd paint over it when I feel like, I never bothered to put as much energy into it. I suspect underneath the paint, the MRP is probably preserved in superb condition, what with the paint taking the brunt of the wear
This MRP AR has been a part of almost all of my product development and testing, there's a lot of history. The EMR (mag button) has its anodizing worn off from repeated mag catch removal while testing our EMR-A, the shadow left by KNS anti-rotation pins bars was me getting tired of having to install and remove them while testing triggers with selectors. The Geissele Airborne CH had blood washed off when a friend mortared the gun trying to extract a stuck case and cut himself with the ACH somehow, while filming the 6315 flash suppressor. The top of the forward assist housing is stripped of paint, because my fingers travel over it when I use the ambi charging handle's right lack to pull back on the CH. That realization back in 2012 led to the LDFA (low drag forward assist), which can be seen in the pic below. 
One day when I'm old and grey, I'll put it in a glass case just to reminisce the journey we took together

A glass case would be a fitting tribute for that MRP, unlike Lenin, isn't he still in a case in Moscow?
http://www.cnn.com/travel/article/lenin-mausoleum-moscow/index.html Remember when there were all the detractors of the MRP upper, "expensive junk", "just carry another complete upper than change the barrel", and "you can't get any barrels for it", or "too heavy" and "damage the rail you'll have to scrap the whole upper", as well as dozens more. Well my short and long MRP uppers would be the last ones I'd ever get rid of. I never did get that 16" MRP barrel profiled for the OPS 12th can, the SpecWar works great on it. And I really use it mostly on the 10.5" and 14.5" barrels. My go to gun is the MRP 10.5" SBR with CompM4 or the 16" Krieger Recon TA11C, but I have put the 16" MRP back into that fold with a USO 1.8-10X scope. It's just always been one of my best uppers, period. |

It's been 13 years, I can't recall, but wouldn't be surprised if someone said it was a solution in search of a problem.
I've built numerous ARs since, and this is the one I shoot all the time. It was well ahead of its time. The monolithic concept might not have taken off, but its continuous rails have more or less become the norm. I don't have another barrel for it, I'm thinking about sending a lighter profiled barrel to have it converted for the MRP, but I'm waiting for a real good reason other than weight, and I've come up short so far. Good thing i have a pic of what it looked like when the paint job was still fresh, it looks considerably worse for wear now

Took the 6.5 and 13.5, 308 out today, took about 10 rounds to get a nice Group out of the 6.5 with American gunner 140smk.
Good ammo, shot a couple 4 round clover leafs with the typical flyer just out side the group. Solid 3/4 Moa combo. The 13.5 ran well suppressed, group wasn't great since I had no mloc panels to attached my bipod, I would say under 2 moa with a mostly horizontal spread. I'm confident with a good position and bipod, it would shoot on part with my other SS lmt barrels. That 6.5 is going to be nice when I finally get a chance to take it to the mountains |
