THE IMAGE ABOVE IS A PAID ADVERTISEMENT It seems to function fine except when I have the bolt locked back. When the bolt is locked back, it is hard to move the selector switch to "SAFE". It goes in place, but is tight and it doesn't snap into place. Upon inspection, I can see that the back part of the trigger is rubbing on the selector switch barrel part inside just a bit. 
This doesn't seem normal. Seems I could file/sand down either the trigger area or the selector switch part that rubs just a bit and it would probably work fine. Also, when the I charge the rifle and the bolt is forward, the switch works like it should. Anyone have any suggestions?? Thanks! |

Problem is not there, but on the hammer itself.
To short bus it, the bottom of the hammer is an oblong cam, and as the hammer is all the way forward uncocked, the bottom of the hammer cams the back of the trigger slightly up to block the selector from going into safe. Now on your unit, With the hammer cocked all the way back via the bottom of the carrier, the front of the trigger is making contact to the area of the hammer just below the sear past the low area in the cam, and is causing the back of the trigger to be raised like if the hammer was uncocked (ride the charging handle back down to bring the carrier forward, and you will see that the trigger will move slightly forward as the trigger catches the hammer. So, either have the hammer replaced, or you will need to lengthen the low cam area on the hammer bottom lob a little closer to the sear area. Note, the hammer is hardened pretty much as hard as a file, so to rework the lob, you need either Carbide end mills, or a diamond file. Due to this, it probable easier to just have the hammer replaced instead. |

Very interesting...... I will check that out. So do you think I just have a bad/defective hammer from ALG Defense?

So like the two said in your thread, should you not engage your safety with the bolt back and ignore this? My thoughts are no, you should be able to engage the safety before you fully charge the rifle, ie bolt locked back. |

My thoughts are no, you should be able to engage the safety before you fully charge the rifle, ie bolt locked back. I tend to agree with you. I removed a very small amount of material from the safety so that it will engage properly with the bolt locked back (I did not want to remove the plating from the trigger by working on that) . |

I think I will do the same thing..........I may talk to ALG Defense and see what they have to say. Originally Posted By Dano523:
