What weight/style buffer is included from the factory with the RRA Pistol lower with the heavy duty fluted buffer tube?
What buffer should I use with a 10.5" barrel if i installed a full length rifle tube? Thanks |

If you had a full length rifle extension, you would need a rifle buffer and a rifle length spring(which isn't the same as a carbine buffer). You could get or make a spacer that would allow you to use a carbine buffer and spring, I think MGI makes a spacer. What weight buffer for your 10.5 will really depend on your gun, as it seems no two ever shoot quite the same. So what works for me may not for you. Run it with what comes with it and see, as you will hopefully not need any modfications. Do a bolt extractor up grade, it's cheap insurance. |

Its a 10.5 RRA upper also. What ever size gas port they used it runs pretty well. Mine came with a chrome lined 1/7 when there website list as non chromed 1/9.
I want to use a rifle length buffer tube because my neck is too long to look down the sights when i try to shoulder it. I know about the nose to charging handle method but my nose it literally on the carry handle. I will need the buffer tube longer to try the over the shoulder method also. I didn't know if it was a carbine buffer as the tube looks even shorter. Why couldn't I use this carbine buffer in a rifle length tube if the spring will be the same rate and just longer. Will a rifle length tube,spring,and buffer work with the short gas system? I might get one of those delrin/nylon spacers so i can use the same spring and buffer that will be compatible with my M4's. I like the way its running with this setup. I just need a longer tube. Also a standard tube,not as thick as the fluted RRA, will allow me to use the foam sleeve and end caps. |

Do you live in a state where SBR's are legal?
If you do then you need to seriously consider just doing the paperwork and putting a stock on there. You won't be doing yourself or any other AR pistol owners any favors by intentionally building your pistol in a way that facilitates shouldering it, and then asking for advice about it on this site. If the only tube you have available to you at the moment is a rifle tube or you just think the gun looks cool with a long tube then yes, you need a rifle specific spring and buffer or a spacer. If you just have the rifle tube on there while you wait for your RRA pistol tube then a spacer might be a way to avoid having to buy multiple springs and buffers. |
| Im looking into a rifle 'length' tube that does NOT accept a stock. Just the slick tube. If i was stocking it i would stick with the shorter carbine length system with a collapsible stock.This is the site that i read about the longer tube and foam sleeve being more comfortable. I actually do not want to shoulder the gun and have it poking me in the chest. I need a longer tube so i can look down the sights with the tube OVER my shoulder. I will be filing for SBR registration but its like a 6 month wait right now anyways and I need something in the mean time. A buffer tube and spacer shouldn't cost that much. I actually prefer the look too. |
