Normal1959 Posted November 19, 2016 Report Share Posted November 19, 2016 We had better be able to afford op rods since this is only 400 rounds.Eric Link to comment Share on other sites More sharing options...
Normal1959 Posted November 19, 2016 Author Report Share Posted November 19, 2016 Anybody know the average service life of the op rod?Bolt looks like new.Eric Link to comment Share on other sites More sharing options...
MG08 Posted November 21, 2016 Report Share Posted November 21, 2016 What "kind" of gun is it installed in ? Original Maremount. RIA or a post sample build ? Something looks to be out of alignment to create that wear. Link to comment Share on other sites More sharing options...

Something looks to be out of alignment to create that wear. RIA and I might be mistaken on the round count. I have 2 m60's and i'm not sure I did put in a new op rod. I started second guessing myself. The other is a new England group.Eric Link to comment Share on other sites More sharing options...
MG08 Posted November 22, 2016 Report Share Posted November 22, 2016 We had three RIA guns back in the late 80s. Lots of issues with running "correctly" We ended up having an opportunity for a Army Armorer to go through them, and he ended up replacing a lot of the internals. Seems the parts were not "Milspec", or were reject govt parts. This could be the case for this part. Also look at the receiver and see if there is corresponding wear to the op rod . The wear on the tower could be the Op rod or could be the bolt having issues. Assuming you dont feather the trigger, Op rods should get 10s of thousands of rds before issues crop up. you might want to review you lubrication plan and ensure you are correctly lubricating the critical points.

HPRA Posted February 11, 2018 Report Share Posted February 11, 2018 ;Question for you '60 guys. Are you using moly grease on the op rod lug where the bolt cams ? Link to comment Share on other sites More sharing options...
Normal1959 Posted February 11, 2018 Author Report Share Posted February 11, 2018 I am now using Lubriplate 130 on all moving parts and wear has gone down 99%Eric Link to comment Share on other sites More sharing options...
MGTedFL Posted March 13, 2018 Report Share Posted March 13, 2018 Mil-Comm TW25B Synthetic Grease at all contact and wear points. Mil-Comm Oil or CLP on everything else. I have an RIA, which was originally in the E1 configuration, except when I got her, she had already been upgraded internally to an E3 op-rod, new bolt, spring and thicker spring rod. She was low-mileage with a tight RIA trunion. Original bolt and op-rod still look good. I swapped the top cover for the billet style and alternate between the original E1 barrel, an E3 (handle removed) and a custom modified E-1 Commando-style (shortened, no bi-pod). Good supply of spares and a mix of E3, E4 and E6 parts/accy. to swap-out...just like my kid's LEGO. What a great platform, as I can reconfigure just a little bit ..... for every shoot. All configurations shoot great, so long as you stick to your lube plan & keep her clean, especially the gas-tube & piston.....and use good ammo.

michaelkih Posted March 17, 2018 Report Share Posted March 17, 2018 I just use gun oil on everything. No grease. Not sure if that's bad? Link to comment Share on other sites More sharing options...
Normal1959 Posted March 18, 2018 Author Report Share Posted March 18, 2018 I just use gun oil on everything. No grease. Not sure if that's bad? I am grappling with the same issue. I notice with the grease, my gun slows down and gets a ton dirtier. Would love to just use oil but still undecided.Eric Link to comment Share on other sites More sharing options...
MG08 Posted March 18, 2018 Report Share Posted March 18, 2018 the oil does not stay on the wear points well. It does not take a lot of grease, but some good quality like Militech or SLP 2000 ( both synthetics) wear well and reduce wear and tear. Link to comment Share on other sites More sharing options...
brucea4 Posted February 18, 2019 Report Share Posted February 18, 2019 I had a M60 years ago and used " Tufoil " all the time. Still use it today on all my guns and never a problem. Link to comment Share on other sites More sharing options...

StrangeRanger Posted May 22, 2019 Report Share Posted May 22, 2019 Am I correct in assuming that the second sear notch on an E6 op rod is there to prevent runaways such as I had when the bottom gas plug fell out? Also a bolt question: can the new style bolts be used in the original version of the 60? Link to comment Share on other sites More sharing options...
MGTedFL Posted May 25, 2019 Report Share Posted May 25, 2019 Yes the second sear notch, first upgraded on the E3 (and the second and third notches in the Danish contract op-rods) helps prevent runaways if the recoil stroke is not long enough to reset the sear, but enough to extract the next round. A problem that can occur with any open bolt gun, especially a fixed-firing pin open bolt gun. This can be caused by under-powered ammo, a dirty gas system and other mechanical issues. By "new style bolts" I assume you are referring to US Ordnance produced and coded bolts? Yes, they are all 100% compatible, but USO bolts rare and expensive. A good original NOS bolt is close to $500 these days. I'm still kicking myself for passing on two new US Ord bolts someone offered me several years ago at a good price. There are very few parts that can not be interchanged between the E1, E3, E4 (Mod 0 & Mod 1) and the E6. For example, you can not put a E3,4,6 barrel on a pig with the E1 hand guard on it, as the handle gets in the way. I have one E3 barrel with no handle just for this. With a stripped receiver and the required parts you can build any version you wish, and mix and match your favorite features into a hybrid pig. I do this all the time. Just about every time I take my pig out to play, she is set-up differently. Franken-pig rules..... Link to comment Share on other sites More sharing options...

An E3 op rod would be a 2-notch manufactured by SACO defenseAn E6 op-rod would be either a 2-notch or 3-notch (Danish Mil spec) manufactured by US Ordnance All are interchangeable function-wise Link to comment Share on other sites More sharing options...
