So i am adding a single point sling from http://gearsector.com/ to my RRA carbine
How do i go about removing the collapsible stock to add the sling mount? Will i need a special tool or can it be done with common tools? thanks for the info! |
| As said in German engineering ......Gut en tite ....... I am sure there is a torque value somewhere, but just getting it tight enough to stay put is fine. Some loctite can't hurt, but I have never used it. There is a great multi wrench out here for like 20-30 bucks. It has a wrench for the castle nut, barrle nuts of many kinds and a spot for a torque wrench. It is a good tool to have. |
| The buffer tube basically goes thru the end plate and screws into the lower receiver and the castle nut tightens it down to the receiver, keeping it from spinning loose. There is a selector detent and spring which is held into the lower recevier by the end plate. That is what they are talking about flying off. You have to unscrew the castle nut enough for the end plate to slide back to unscrew the buffer tube. Sounds crazy but makes sense when you see it actually done. |

c Quoted:
can the castle nut come off with the buffer tube wanting to fly back? If the sling attachment goes between it and the end plate then all he should have to do is take off the castle nut and put the attachment on between them right? Yes, but to do that, he is going to have to take out the buffer spring and tube, then he is going to have to unscrew the buffer tube from the lower reciever. When he does that, the plate with come off with it. In which case, the spring will want to fly out. The spring and pin holding in the buffer will also want to fly. He will then put the sling attachment between the plate and castle nut (I do it that way anyway, sometimes you can just replace the plate with the sling attachement) and screw the buffer tube back into the Lower reciever until it holds down the buffer retaining spring and pin. He will need to hold the plate against the lower reciever to keep spring from flying out and then tighten down the castel nut to hold everything tight. Hope that makes sense. |

No, the spring is going to start pushing the endplate back as soon as the castle nut is loosened. The endplate is not attached in any way to the weapon, it's merely held in place. Unless it's a clamp on mount, the buffer tube is going to have to come off to install the mount. The endplate has to come off to get the buffer tube off, unless you want to cause permanent damage to the buffer tube. There's a little tongue on the endplate that engages a groove in the buffer tube to keep the tube from spinning. There is a mod you can do to capture the take down pin detent and spring. The hole has to be threaded, the spring shortened, and a set screw installed behind it. |
