Is it possible for me to put http://www.vltor.com/mur.htm

This part, into a Ruger SR-556?

I would like a gun with no forward assist. Thanks.
 
Call them and ask, my intial guess would be NO the SR-556 is a piston system and not a DI rifle.

Piston or DI, they use the same upper 99% of the time. The difference is that instead of a gas tube coming in the front of the upper, the piston rod goes in there. In some cases, there is a steel bushing pressed/driven into the upper to prevent wear, but otherwise it is a normal AR15 upper. The Ruger uses a standard upper.

This was actually the one I wanted. With the dust cover but no forward bolt assist.

That sure looks like a cobbed-up piece of weirdness to me. What in the world is going on under that "deflector" taped to the side?
I'm thinking what you're looking at there are items salvaged from an otherwise scrap run.

You really have no idea, do you? The non-FA version looks a bit odd, but VLTOR makes some of the highest quality AR products of anyone. I have the FA version of the MUR and it is very well made, not cobbled together scrap.

OP: I have three comments on your idea:
1) It will probably work, but might require enlarging the hole where the gas tube would normally go.
2) It's lipstick on a pig.
3) Be aware that the MUR holds tight tolerances and I've found that mine is a very tight fit on several of my lowers. Some people would say this is good, to me it's a nuisance.

In fact I do have an idea and my opinion is based on well over a decade in manufacturing ARs - not assembling them but rather manufacturing from design to sale. That piece in the photo I copied is without a doubt a salvage from one form of manufacturing mistake or other. At least that's the good version of how that might come to be in the state it is presented.

I'm certainly not commenting on quality but the photo speaks for itself in its demonstration of compromise.

Perhaps you should actually look at one and how it is made and the design behind it before passing your holy judgement. No way it was a "mistake" or "salvage" unless they solved the machinists' riddle of how to add material back.

Yup - five pieces added to the photo that I'm talking about.

It occurs to me that I've said my piece and stand by it but the sub topic has become divergent to the OP's question - so, I'm outa this thread rather than have it locked before the OP gets his project done.

Overpriced with the name Ruger on it....so many other better choices for less monehy and no Ruger name on it, and I am a ruger fan.

I paid $995 for mine. Guy had bought the $1499 version and used it lightly for one year then decided he wanted something else. I was happy to let him sell it to me for a $500 loss. Changed the Ruger flash hider for a Battlecomp. Changed the stock to a Magpul and put a SSA-E trigger in it. Few other parts as well. I'm very, very pleased with the rifle. I have a whole safe full of AR's and that Ruger is probably my favorite out of them all right now. Of the 5.56 ones at least. It works very well.

I still want to hear the explanation for this statement??

If the round isn't going into the chamber "willingly" then why on God's green earth would you want to force it in? Maybe there's crud or something bigger jamming it; and thus there is a possibility of increased pressure and the gun blowing up.

2) The bolt assist costs a LOT to manufacture in the tooling stage; it offsets structural integrity; makes the gun look unbalanced; and is not necessary. If the round won't go in, forcing it in is the LAST thing you want to do. Square peg, round hole.

Salvaged? Really? That's your conclusion? Where do you get that from?? It's a manufactured one piece; with the bolt assist hold covered.

The Rugers on the auctions sites are all less than $1000. That seems fairly cheap for a piston driven AR. I'm not getting now it's overpriced when most AR's run in the $1500's.
 
Don't use the bolt assist to jam it in.

Use it for a press check to ensure the status of your weapon without making a lot of noise.
