Situation: New DPMS Recon (comes factory Magpul Collapsable stock, 16 in Barrel).
Question: When is it nessecary to used the modified heavy buffers and springs for the 308. I am familiar with the 5.56 world are various length gas systems, how about the 308––is the stock buffer/spring system reliable or no? |
| DPMS rifles generally tend to be overgassed, so a stiffer spring and/or heavier buffer could reduce felt recoil, increase lock time, increase parts life, etc. Look at your ejection angle. Your brass should be ejecting from around 3 o'clock to around 4:30. Overgassed will eject from about 1 o'clock to 3. |

I am familiar with the 5.56 world are various length gas systems, how about the 308––is the stock buffer/spring system reliable or no? No it is not "necessary" as the stock parts will function. Many people have upgraded certain parts though. Many believe that 308s are over gassed so they replace the gas block with an adjustable gas block. There are adjustable gas blocks with a locking detent to keep the adjustment screw from backing out. Some use a heavy buffer too. Using both should be ideal. It supposedly tames the over gassing problem reduces recoil significantly. I might be doing both upgrades in the future with my MEGA MA-TEN. I'll likely start with the adjustable gas block before paying over $125 for a buffer. |
