I will be shooting some hard primered ammo soon. I know my MBT has failed to light several 7.62x39 primers and these 5.56 primers will be just as hard. I've got a bunch of Wolff XP springs and I would like to put the XP springs on my MBT's. Does anyone know if this will cause issues?

I can't directly answer your question but the LaRue hammer spring is coneical wound to provide consistent force. If the wolf springs aren't that possibly could cause an issue? Try some firing with spent rounds to try the wolf spring? |

I don't think the XP spring will cause any issues, might not have a service life as long as Larue's spring, but should deliver more force. It could cause an issue if it's wider than the MBT spring, but I don't think it is. |

If you want a nasty, stiff, trigger/hammer spring setup. Use a polished factory trigger group.... They are pretty cheap from PSA. Save the good trigger for a good caliber like 6.8 SPC.......
I actually like 7.62x39, but only in my AK, hehehe!!! I know the Wolf primers are cheap, but as hard as the primers are, why risk your life on an unreliable primer? I know that in an AK, they are very reliable. That's because the trigger/hammer geometry is designed to make them go bang. The AR-15 trigger geometry isn't really designed for that hard of a primer. One other thing to consider, a lot of people who shoot 7.62x39 based ammo in their AR-15 change their firing pin to a Heavier duty unit that I think may be fractionally longer, seems to help. Been a long time since I delved into this area so do a little research and you will probably find the info I'm talking about...... |

I got a batch of very cheap hard primered .223 that I plan to use for training ammo. Golden Tiger ran a batch of .223 using 5.45 primers without realizing it would cause issues. Now it's being sold for .16/rd + shipping. I've also got several of the extended firing pins I'll be using in every setup that will get some of this ammo. |

Don't do this:
If you bend the legs down away from the hammer it will add some wrap to the coils and increase force. Ensure both legs are bent exactly the same. I'd try a 30 degree angle (incrementally to insure enough spring leg wire still rests on trigger pin) using needle nose pliers to hold the spring and also as spacer from coil bodies to ensure matching bend lengths. Personally i would have a spare OEM spring from LaRue in hand before attempting. Mech |

I dropped a Wolff XP spring in last night. No issues on the function check. Next up is live fire.

I am trying to finish off an AR-10 build using my Field Grade LaRue barrel and an MBT as we speak. If I could legally make a carbine out of it, all I would need is a forend, but I could still shoot it from a bench rest with the barrel on a bag. But thanks to California commies, I have to make it a fixed stock, so I still need a fixed stock and a .308 A2 style buffer before I can shoot it. Just don' have the cash on hand to buy it right now. $1500 dollars of parts/labor going into the worn out front end of the 4x4 as we speak..... |

I've thought about it, it's a magpul ACS stock. Looked like it may do more damage to it than help. I am certainly not getting rid of any parts. I plan on moving out of California when I retire in a few years, then I can convert everything back. Just blessed to have three AR-15's and two AR-10's. The AK had already been converted to a featureless rifle due to the bullet button configuration on those being such a pain to use.

You can do that, but there are a lot of restrictions as to where you can take an "Assault Weapon" and how it has to be packaged. Also, you can't transfer an assault weapon to your kids. The main reason I don't want to do that is: If you register them, they know where to go to get them... There's only one reeason for registration, that's to ease confiscation...... |

Register some, bury some. Then you can train openly. If your kids move out of state you would be able to transfer it to them then.

Any input from the guys at Larue on long term wear or voiding my warranty with this mod?
|

I would seriously doubt it. I don't think you're going to wear an MBT out in one lifetime.... It would be fun trying though!!
