6132expert Posted February 29, 2012 Report Share Posted February 29, 2012 Does anyone know if the wrench is the same for the TRX and MFR? Troy only shows the wrench for the TRX. Also does Brownells sell a wrench for the Troy nut? I cant find one at their site. <dontknow> Quote Link to comment Share on other sites More sharing options...

survivalshop Posted February 29, 2012 Report Share Posted February 29, 2012 I have all kinds of barrel nut wrenches & may have one to fit your bbl. nut . Need specifics or a photo & I can send you one to use . I keep most in the org. boxes or bags so it may be identified. Quote Link to comment Share on other sites More sharing options...
6132expert Posted February 29, 2012 Author Report Share Posted February 29, 2012 I would really rather buy a wrech, if anything happened to one I barrowed I would not like that. If you have a good wrech to sell I would buy it. Or post me up a link to buy one.Would this be the one I need?http://www.brownells.com/.aspx/pid=27412/Product/AR-15-M16-AR-10-reg-BARREL-NUT-WRENCH Quote Link to comment Share on other sites More sharing options...

I used the dpms/ar10 wrench like this <thumbsup> Washhttp://www.operationparts.com/Brownell_s_Dpms_Ar_Style_308_Barrel_Nut_Wrench_p/231-000-230.htm Quote Link to comment Share on other sites More sharing options...
6132expert Posted March 1, 2012 Author Report Share Posted March 1, 2012 I thought it looked just like mine. Thanks for the info and I will keep it in mind. Anyone else have any suggestions I would rather buy from Brownells for the site when I order the barrel jaws. Quote Link to comment Share on other sites More sharing options...

Also does Brownells sell a wrench for the Troy nut? I cant find one at their site. <dontknow>As you found, from talking to the Troy rep - the MRF barrel nut is perfectly round, with wrench flats in it, machined into the front (muzzle) end - you can install it with a large crescent wrench. It takes no special barrel nut wrench.Outer-dimension wise, it's identical to a stock Armalite AR-10 barrel nut, except it doesn't have the teeth - just the wrench flats where those teeth are. Looks just like this Armalite here, but no teeth: Quote Link to comment Share on other sites More sharing options...
6132expert Posted March 1, 2012 Author Report Share Posted March 1, 2012 You say it can be installed with a crescent wrench now be specific. Crescent is a name brand not a type of wrench. The nut does have teeth like the Armalite nut you show just not as tall. Its understood by me that the Armalite nut is different then the DPMS nut and a standard AR15 nut. Is this correct?

edgecrusher Posted March 1, 2012 Report Share Posted March 1, 2012 most people reference a crescent wrench as your standard adjustable. can't help on the rest Quote Link to comment Share on other sites More sharing options...
6132expert Posted March 1, 2012 Author Report Share Posted March 1, 2012 that also, clear on what is being said. I can see what he is saying about the flats on my barrel nut. But that really dont give me a way to do a specified torque on the nut. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted March 1, 2012 Report Share Posted March 1, 2012 The one "washguy "put up is a combo wrench for both DPMS & AR 10 barrel nuts & should work . Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted March 1, 2012 Report Share Posted March 1, 2012 This might be a little red-neck of me, but I have used a small strap wrench in the past. Im not suggesting it as a good idea.... But it worked for me!I still use a strap wrench when tightening full length buffer tubes that don't lock in with a castle nut. Quote Link to comment Share on other sites More sharing options...
washguy Posted March 1, 2012 Report Share Posted March 1, 2012 Hiya Heres another wrench that works fine on my troy barrel nut...I purchased this one at a gun show after one of the oh so brittle pins snapped off the dpms wrench Washhttp://www.thewilderness.com/storepinnacle/index.php?p=product&id=2773&parent=212 Quote Link to comment Share on other sites More sharing options...

Is this correct?Not yours, man, not the TRX nut. The MRF nut has the wrench flats on it - that's the one I was describing.If you go back to your original post, you stated that Troy only sells the wrench for the TRX, and not one for the MRF - What I was explaining above is why they don't sell a wrench for the MRF - it doesn't take anything special, due to the design, and those wrench flats. <thumbsup>You could tighten the MRF nut with a pipe wrench. <laughs> Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 2, 2012 Report Share Posted March 2, 2012 6132, here's a better example of what I was trying to describe about the MRF barrel nut - this one right here is made by Samson. The Samson pictured here has 6 wrench flats on it, while the MRF nut only has the two wrench flats.Thread about the Samson:http://308ar.com/forum/308ar-parts/samson-barrel-nut/msg19930/#msg19930I know this is no help to you, with the TRX, but I hope the difference between the TRX nut and the MRF nut is a little more clear. If not, I'll try to do better. <thumbsup> Quote Link to comment Share on other sites More sharing options...
Retired JM Posted March 2, 2012 Report Share Posted March 2, 2012 This might be a little red-neck of me, but I have used a small strap wrench in the pastNot redneck at all. Armalite recommends using a strap wrench for tightening/retightening their barrel nuts Quote Link to comment Share on other sites More sharing options...
6132expert Posted March 2, 2012 Author Report Share Posted March 2, 2012 I don't have a TRX rail. It says right on the box that it is a MRF , BUT the barrel nut looks like a TRX nut.This is a TRX nut and you saw the picture of mine.6132, here's a better example of what I was trying to describe about the MRF barrel nut - this one right here is made by Samson.

6132expert Posted March 3, 2012 Author Report Share Posted March 3, 2012 Ok I got her figured out. The TRX nut and 308 MRF nut are almost identical with the exception that the MRF nut has two sets of teeth a large set lime the TRX and a smaller set that will except a standard AR15 wrench.

Team Helotes Posted March 3, 2012 Report Share Posted March 3, 2012 308 MFR can be tightened with a standard AR barrel wrench. Quote Link to comment Share on other sites More sharing options...
