Hey Broc, what trigger pins are you using? we have had problems with some customers using JP and other mfg's Anti walk pins when installing cartrige style triggers that are designed for standard trigger pins. there are a few anti walk pin manufacturers who are actually making thier pins oversized to get the best possible alignment for Jard, JP, hyperfire, or Geissele non cartrige type triggers the oversized pins make alignment a big problem because it causes dimensional interference in the front of the fire control group pocket ( where you are seeing the friction marks. But if your having the problem shown with the supplied triggers the issue would identify a out of spec lower reciever dimension. hope this info helps if you have anyother Q's hit me up with a PM TK Product Development MGR Adams Arms

not to imply anything but do you know if the spring your using is a rifle or carbine length? if so i would like others here suggest reducing the gas not increasing the resistance of the recoil system if your trying to lighten perceived recoil the use of a heavier buffer is great for slowing down the operating cycle and bleeding off some of the bolt velocity of a tactical gun but if your intent is a competition rifle you would be better suited to reduce the gas force and decrease the mass of your reciprocating parts to create a lighter recoiling and less disturbing rifle.

on page 1 of the thread i saw some questions about utilizing light standard and heavy weight buffers while configuring your 3gun build's i wanted to pass on a bit of information that may help Reliable functioning of the AR platform in Direct gas (DI) or Piston configuration is an equation of two factors Energy (X) required to overcome Resistance amount (Y) (X)Ek > (Y)Ep = Reliable function If a rifle is failing to function I.E. (Feed, Fire, and Eject) The method to correct this is Add Energy (X) and/or Reduce Resistance (Y) (X) Ensure Gas Block to Gas port alignment, Inspect Gas System for obstruction or wear Replace if necessary, Increase Gas Pickup (Y) Use- Reduced Power Buffer Springs, Lightened Carriers, or Lighter Weight Buffers Thanks, TK

Thanks for all the good words guys! everyone here at Team Adams is proud you chose us to be a part of your 3gun Setup!

Sorry there are no project plans in the works for .223 wylde chambering. Given the huge amount of surplus nato ball and fluctuation in commercially available ammunition we decided to run all barrels to .556 for reliable chambering of the majority of munitions out there. Iv personally had my Wylde chambered Barrels cut to .556 after i had to spend a night chamber forming 400rnds in my hotel parking lot the night before 2011 FNH champ. not saying its not a good mix of the two chambering just saying when i spend about $1000 to go to a major match the last thing i want holding me up is my ammo not going into battery cause its LC brass.

Hello all, I just wanted to offer clarification on a few things from previous post's 1.) Polishing the chamber in VDI barrels will not get any where close to removing the nitrocarburizing in the chamber. The Hardness of the coating is greater than twice the depth of the pigmented material is. Meaning that you could get in there and polish the chamber to the point that there is no pigment showing just shiny bare in appearance metal, and you still wouldn't have removed the coating. 2.) All our VDI barrels do have a lifetime warranty and we will replace any faulty barrel immediately, has anyone identified any faulty barrels or any failures to function on this thread? "My concern is if there is any POI shift after the skinny barrel heats up. Generally, the long range stuff at the local matches here is engaged after 5-12 closer paper targets. I'm interested to see if you guys notice a POI shift after about 20 or so hoser shots" 3.) Light profile barrels do heat up with less rounds than their heavy profile brothers, the upside is that they also cool quicker ( a advantage in 3gun while your rifle is on the rack and your pasting your hot barrel will most likely be back to ambient temp before your on deck at the next stage.) I'm a pretty avid 3 gunner. I also shared the skinny barrel concern when i went to do my first light fast gun build out. So i conducted this test on my personal 16.5" to see at what point heat began to affect grouping tested as follows. conduct initial group and zero. return to ambient temperature ( tested with a laser thermometer) fire one magazine cyclic drop to sandbag and group record any change. return to temp and re group record changes. at 90rnds cyclic (3mags) on the immediate group i had a 1.25" group relocation to the 7 o'clock at 200m the grouping stayed within the average of diameter but was off zero by 1.25" after cool down to ambient temp the group returned to zero. in my opinion unless your firing greater than 90rnds as fast as you can and then shooting sub .75 moa targetry i wouldn't be concerned with the lighter profile barrels for 3gun competition rifles. Thanks for all the great feedback on the barrels guys. all the builds on the thread look awesome! Thank you all, TK Martindill Product Development Mgr Adams Arms Voodoo Innovations
