| My newest FrankenAR sometimes double shoots when i pull the trigger any ideas to why ? |
No it doesn't. Not at all. How does it even remotely sound like a slamfire? Could be your trigger spring, could be a bad disconnector/spring. Check out the troubleshooting, maintenance, and BIY forums. Doubling is usually a result of bad/misaligned FCG parts. If this is a frankengun with possibly suspect parts, you might want to check the engagement surfaces of the trigger, selector, hammer, and disconnector. You might have underspec pins or overspec pin holes. The safest and most sure way to fix it (if checking the springs doesn't help it) is to replace all of the FCG parts. ETA: You might want to check the -23&P under the Direct Support chaper (3, IIRC) for the troubleshooting procedures and checks. |
| We got a LOT of M-16A2s in the armoury that have this same problem. We pretty much narrowed it down to worn hammers although you might want to check the trigger nose as well. In our rifles, it fires once when you fire it, then again when you let off the trigger, especially if you let it out slowly. |
hey, can I get one of those

| Rooster; You need to static-check any semi-auto gun before taking it out to fire. Make sure the gun is unloaded and remove the magazine. Cock it and pull the trigger and hold it down - the hammer falls. While holding down the trigger, pull the operating handle or slide back again and let it return. Release the trigger - the hammer must not fall. Pull the trigger - the hammer must fall. If your gun won't pass this, you shouldn't fire it. Also, the law regards any 'doubling' gun a machine gun, so you want to fix that. Check the trigger and hammer. |
Also, a hammer, trigger, disconnector and their respective springs are pretty cheap. If you have the slightest doubt of the safety or functionality of any of these parts, invest in a new set from a reputable source. |
I had this issue once....did this...cut down to orange area to increase the disconnector engagement. Just don't file it too much or the AR won't fire. Also remember that it pivots, so the cut should be more at the tip - less at the base. Usually a little bit will work, .010 should be enough to cure the problem. Function test after each little bit. A 5/32 punch will make the work easier, use it as the pin replacement, only pulling it out enough to release the disconnector from the trigger each time, leaving the trigger in place...and make sure it is all the way through both receiver pin holes when you function test the weapon. 1. put your thumb on the hammer, and pull the trigger to release it.-do not let the hammer fall free into your receiver or damage may occur 2. keeping the trigger pulled, re-cock the hammer with your thumb, engaging the disconnector. 3. keeping your thumb on the hammer, release the trigger slowly. if the hammer does not catch on the primary sear surface and tries to fall (fire) remove more from the disconnector's movement limiter (area in orange) |
Ok worked like it should on this one. P.S. this is one of those Cav Arms lowers that came complete with I think a DPMS trigger group. forgot where I bought it but it was from one of AR15s industry section. think I paid like $150. So all my parts are new. |
