Looking to do my own build for a 308 It appears there will be some diffrent issues than with the ar -15 Can you guys give me some info on things to watch for, Planning on a sniper type setup. he |

If you've built an AR-15, a 308 shouldn't be much of a challenge. The first choice is which lower to base your build upon because that dictates the upper receiver: Armalite/Eagle Arms -or- DPMS/Fulton/POF The upper receiver dictates the barrel nut because Armalite and DPMS thread pitch are different. Many free float tube/rail manufacturers offer nuts in either pitch. The gas port on Armalite barrels is further down the barrel, requiring a unique long gas tube. Other than that, a 308 goes together like an over sized AR-15. |

Now that Armalite has their gen 2 mags, there isn't much difference between them. Choose either and you can build a fine rifle. While the upper receiver must match the lower, you can interchange the barrel assemblies and the bolt/BC assemblies. It is my experience that headspace is OK with either. One of my two 308s is running an Armalite barrel and DPMS bolt/BC. The only caution is using A DPMS rifle barrel with an Armalite rifle length float tube. There will be interference if the gas block is too big because the Armalite handguard is 3/8" longer than the DPMS handguard. |
