Being new to this forum I'll give a quick run through of my gun.
I built my ar just over a year ago, it is by best a mutt brand. By this I mean I picked up a stripped lower, bought a kit, and have modified most every part of it I can. It shoots almost as accurate as my .243 and after working out a few kinks cycles almost flawlessly. Now to the problem, I never really use the forward assist but awhile back I was stalkin some hogs in the middle of the night and wanted to engage the bolt quietly. I then push the forward assist a few times and nothing happens, I think the bolt is engaged... WRONG! Go to shoot and nothing happens, hogs start to move I rip the charge handle then let it drop and by the time I get back on the scope they are into the woods. I check the gun the next day by slowly engaging the bolt a few times and it never fails to not go fully in, the gun is clean mind you. After these attempts I depress the forward assist, every time nothing happens. I take the forward assist out and it appears to look just like the new ones for sale online, when I pull the bolt and hold it in the gun with my hand I can feel the forward assist grabbing just enough to keep the bolt from sliding out but it never moves it... So what I'm asking is what do I have to buy or modify this time?

Your forward assist assembly or your carrier could be out of spec. Check the pawl and spring recess of the assembly for burrs. have modified most every part of it I can There are no parts of the AR-15 that need modification to achieve high accuracy and function. I have built several AR's that shoot 1/2 moa or better with all standard components. A little polishing here and there is all that is necessary. |

A little polishing here and there is all that is necessary. There are no burrs on any part of the forward assist, I just pulled it and looked Monday, but thanks for the advice. I meant I've changed out multiple parts, and yes I have polished some of the internals. Not that I was hacking pieces off to save weight or something like that, sorry for the misdirection. The upper's internals have not been modified in any way. |
| Personally I have probally only used my foward assist twice in actuall shooting.... I have the habit of locking the bolt back and useing the realease more than the foward assist.... Id take it off and check the dogleg tooth on there and see if it is not sharp enough to engadge the cogs cut into the BCG. Other than that Id replace it they are cheep enough like 12 bucks....If you can post pics of it when you take it out and mabey one of us can give you a opionion.. |

Check the carrier to make sure that the saw cuts are all the way back on it.
Punch the cross pin retainer for the FA, and pull the assembly out of the to confirm that the pawn spring is in play, and the pawn is cam'g all the way open. When you reinstall the retainer cross pin, make sure that it goes into the releif slot of the FA, and not acrose the round part that will lock the the FA up.
