I have a LR-308 that I currently have a Magpul CTR stock on but with optics is does not offer a great cheek weld. I am thinking of changing to a Magpul PRS stock but am unsure of how this affects my extension tube, buffer and spring (currently have a Slash buffer/spring).
What extension, buffer and buffer spring is recommended to use with the PRS stock? |

Yeah, your'e going from a carbine setup to a rifle setup. Different tube, spring and buffer. What he said! I have PRS on a brand new rifle, It works great for a fully adjustable stock - I'm actually removing it and going to sell it because i need more length of pull. Let me know if you are interested. regards, Keigan |

Well I figured I would need to change, but do I just use a standard A2 extension, buffer and spring or is there a special buffer and spring that is recommended? When I was putting my CTR together everyone recommended the slash buffer and modified AR10 spring. |

Interesting but says it is not made for AR15/M4 type rifles as it interferes with the operation of the charging handle. |

Check with Magpul... they will tell you that you need a Mil-Spec Rifle Length Tube.
Check with your rifle manufacturer as to which Mil-Spec Rifle Length Tube you can install. My DPMS SASS .308 has the Mil-Spec AR15 Rifle Length Tube with the Magpul PRS. Your results may vary..... Regards, Keigan |

In doing more research, I may go with the ACS instead due to the lack of a QD swivel attachment on the PRS plus the hassle of having to change receiver extension, buffer and spring, especially since I have a high dollar Slash buffer and spring that I have never even shot with.
In addition I am having trouble locating a FDE AR10 model PRS in stock.

What you will need is AR-10 rifle buffer and Spring. Armalite has those in stock. RJ Mike_from_Texas said that he had a LR-308, not an Armalite. For the LR-308, he can use a standard AR-15 rifle receiver extension tube. He is better off getting the DPMS buffer 308-BS-11 and spring 308-BS-10B. If there is a difference in the dimensions or weight of the Armalite BCG and/or buffer, the results won't be good. C_m |
