I'm building an A2 as my first build. Using the Zediker Builder's Guide as my "assembly manual" and the author advocates using a heavy buffer and string, even in a rifle-length gun. I'm getting ready to order my stock and related parts, so would a Wolf "Extra Power Buffer Spring" be beneficial? What about the buffer? The only rifle buffer I see (DPMS) is about 5.2 oz. but I see some carbine-length buffers up to 6 oz> Would a heavier buffer be beneficial? If so, why? Will the carbine length buffer work OK with a full size A2 stock?
Barrel is 20" HBAR, 1/9 twist, ammo will mostly be "5.56" with 55 gr. bullets, maybe some heavier bullets (up to 69 gr.) once in awhile. Thanks, Ken |

Are you using a rifle length receiver extension (AKA buffer tube)? If you are then just use the standard ~5.1-5.2 oz rifle buffer. As to springs, you can just use the standard one and replace it every 3,000 to 5,000 rounds, when it gets too short. The Wolff spring is fine and might last longer if you are shooting a lot of 5.56 loads out of your rifle. I use the Chrome Silicon springs from Brownells, as they are under $5.00. Glen is a HP guy and some of his suggestions are geared more towards that usage. |

Hi Bill,
Thanks for the reply. I will be using a rifle length buffer tube. Not sure about the HP stuff yet (I'm assuming you mean heavier bullets) because I don't know if they'll give good accuracy through my 1/9 barrel. This is my first build, mainly doing it as a learning experience. If it works out I might replace the barrel with something better and faster twist, either a Shilen or Kreiger (whichever I can find), but want to find out if I can build a rifle before dropping big bucks on a barrel. Cheers, Ken |

Cheers, Ken HP = High Power When you are shooting at 600 yards with a .223, many guys have a heavy hand on the powder scale. Here having a heavy buffer, or a bolt carrier weight, can help with retarding the unlocking of the bolt, so the primers might not 'pop' on their reloaded ammunition. Most of the bullets under 73gr can be stabilized by a 1/9" twist, and depending upon just how fast the twist really is, you might be good to go with the 75gr and 77gr bullets. Or not. Once this build comes together, check out this thread. http://www.ar15.com/forums/t_3_18/328143_RIBZ_____Revised_Improved_Battlesight_Zero.html |
