Can anyone here help our friend with that? Quote Link to comment Share on other sites More sharing options...
unforgiven Posted July 12, 2012 Report Share Posted July 12, 2012 http://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=451barrel nuts/threads are proprietary. the web site warns against mix and match. Quote Link to comment Share on other sites More sharing options...
tjtorborg Posted September 12, 2012 Report Share Posted September 12, 2012 I am also in need of a RRA wrench. Anyone got one they want to sell or rent?Thanks,Tom Quote Link to comment Share on other sites More sharing options...
unforgiven Posted September 12, 2012 Report Share Posted September 12, 2012 Just called RRA and didn't realize that there was a specfic wrench for Lar-8 series Part no.308-A-0162 @ $70.00 :o.Tech mention some shops were making there own but didn't elaborate.

tjtorborg Posted September 12, 2012 Report Share Posted September 12, 2012 I actually have one on order along with some other parts. The problem is that even on parts there is a 60 to 90 waiting period. The not knowing is what's killing me.Tom Quote Link to comment Share on other sites More sharing options...

The not knowing is what's killing me.TomParts and accessories, that are not part of a complete rifle or complete upper, should ship with 7~10 business days. That's their current policy, and has been for a long time now.Last statement in this notification:http://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_ID=452 Quote Link to comment Share on other sites More sharing options...
tjtorborg Posted September 13, 2012 Report Share Posted September 13, 2012 I called RRA this morning and the nice lady on the phone said that the barrel nut wrench was on indefinate back order. :-[ She also pointed out that the order was to be complete before shipping.:o I had her change that to ship each item as it becomes available. A friend of mine is a professional machinest and I think I'll have him make me a wrench. Actually he could probably make a small batch that we could offer for a small fee to others. I wonder how much interest there would be for them? Let me know if you guys would be interested in a wrench and what you think would be a fair price.Thanks,Tom Quote Link to comment Share on other sites More sharing options...
unforgiven Posted September 13, 2012 Report Share Posted September 13, 2012 I have the Standard operator 20"HBAR,anything less than $70.00 would be good brother Tom.Rene Quote Link to comment Share on other sites More sharing options...
tjtorborg Posted September 18, 2012 Report Share Posted September 18, 2012 Update.....I ordered three dirrefent wrenches last week. Two from Miday at about $22 each and one form Brownells that was $70 after shipping. The first to arrive were from Midway. Neither of them fit. One was close and a little modification to one pin and it would have worked. Monday I got the one from Brownells and my prayers were answered! It fit the standard barrel nut and it even fit the free float tube nut that I will be using. Here is a link: http://www.brownells.com/.aspx/pid=24190/sku=851-115-001/Product/-308-Armorer-s-Wrench. Now your milage may vary but this wrench works for meGood Luck,Tom Quote Link to comment Share on other sites More sharing options...
unforgiven Posted September 18, 2012 Report Share Posted September 18, 2012 Good deal brother Tom,a little cheaper than RRA and probably got it sooner.Although RRA has free shipping going on with over $25.00 spent. Quote Link to comment Share on other sites More sharing options...
Hoot Posted October 8, 2012 Report Share Posted October 8, 2012 As much as it pained me to do so, I took my 3-pin nut wrench and ground off the center pin. NBD getting two pins to line up. I don't like not having the 3rd pin like every other nut I own uses (thanks a lot RRA), but the two remaining have not shown any undue suffering from having the shoulder the burden. $70.00 for a proprietary nut wrench is extortion. Unavailability is insult to injury. Message received. "We want you to buy entire uppers and not be able to save a little money by discovering that DPMS barrels fit just fine." >:(Hoot Quote Link to comment Share on other sites More sharing options...
tjtorborg Posted October 8, 2012 Report Share Posted October 8, 2012 Hoot,So you were able to use a DPMS barrel on a RRA upper? Also, which wrench did you modify? Was it just a standard DPMS wrench?Thanks,Tom Quote Link to comment Share on other sites More sharing options...
Hoot Posted October 10, 2012 Report Share Posted October 10, 2012 Hoot,So you were able to use a DPMS barrel on a RRA upper? Also, which wrench did you modify? Was it just a standard DPMS wrench?Thanks,TomYes Tom. A 24" DPMS 260 Rem barrel to be precise. Fit like a glove. A bit front heavy though given how light the Predator HP is. Some weight in the A2 stock rebalanced it out though. Also yes, a DPMS nut wrench. Seems like this is a well kept secret for some reason. Triple Deuce used one also, but in his case, I believe he kissed the chamber for a little more breathing room. Mine headspaces tight, but not dangerously so. Actually feels like a custom lap to fit job. Perhaps I was lucky though. I guess a lot depends upon how closely DPMS barrels are toleranced from one to the next. I probably should get a dedicated bolt for the 260 instead of sharing the 308 bolt between the two. This summer was a poor one for disposable time and I didn't get as much opportunity to work up both calibers as I would have liked. Now we're sliding into deer season prep, followed by a long, cold, winter up in these parts. I look forward to having back at it next spring though.Hoot Quote Link to comment Share on other sites More sharing options...
Tripledeuce Posted October 10, 2012 Report Share Posted October 10, 2012 As an interesting aside: While my chamber was a "tight" go, simply turning the reamer by hand removed several thousandths from the diameter of the chamber. The aside is- the rifle shot BETTER with the chamber opened to min specs. Even the benchresters know that that there has to be a slight , but real space for brass expansion.

Hoot Posted October 10, 2012 Report Share Posted October 10, 2012 Terry's experience, which preceeds mine, may well be a testimony to the "diversity" of DPMS tolerances. With my barrel, I can take my stripped bolt and drop a Go gauge into the chamber. Then put the bolt into battery by rotating it firmly pinched between my thumb and index finger. Ditto on factory new brass. That having been said, fired brass exhibits zero shoulder advancement, which probably is not the best setup for the pressure curve. Feeds and extracts fine though. Again, I need to spend more time with it aside from the functional test and a couple of loads I tried last spring.Hoot Quote Link to comment Share on other sites More sharing options...
Tripledeuce Posted October 11, 2012 Report Share Posted October 11, 2012 My fit on the headspace gagues was he same as Hoots. Bolt would turn into position with the go-gauge,but you could feel the gague. By hand turning the reamer, I removed only on he diameter of the chamber. I did NOT affect the headspace at all.

I seem to remember somewhere reading the the LAR-8 has a more pronounced feed ramp because of the design around the FAL mags. I want to build a new RRA upper with a DPMS 260 barrel for my LAR-8 and this was the part that halfway worried me about the whole idea.
