RickedRoss Posted July 31, 2017 Report Posted July 31, 2017 So google didn't make things clear for me. I just started shooting a gas gun series and I am trying to take parts and use them I currently have to supplement the cost of another rifle. I have a jp roller trigger with .156 small pin screws. I get you can use 5.56 triggers in a 7.62 gun but sometimes they have problems with military style ammo (primers). How true is this? What ar-10 lowers run small pin holes? I am unclear how common this is. Am I foolish to try and make this work?
shepp Posted July 31, 2017 Report Posted July 31, 2017 Welcome to the forum feel free to tell us about yourself in the intro section
98Z5V Posted July 31, 2017 Report Posted July 31, 2017 Large-pin triggers are from ONE manufacturer ONLY.. Colt. During the Bill Clinton-Ban Era. ONLY. No other manufacturer ever used that shiit, but Colt.
blue109 Posted July 31, 2017 Report Posted July 31, 2017 AR15 triggers usually work in 308s, but not all 308s are built to the same spec so occasionally there are combos that dont play nice. Some have issues setting off milsurp primers but most factory ammo pops fine.

survivalshop Posted July 31, 2017 Report Posted July 31, 2017 If you have issues setting off MilSpec Primers , there are several companies that make stronger Hammer Springs to remedy the issue ( the one piece Modular FCG's may be different ) . Most FCG's don't have the issue , I have & I'm sure some here have more , but I have probably a half doz. different FCG's I've tried in 308 AR's & have not had one issue with setting off primers on Milspec ammo .
blue109 Posted July 31, 2017 Report Posted July 31, 2017 I can say for sure from experience timney(ar15 version) and velocity have issues with hard 308 primers. I had an RRA trigger that would hit the bottom of the carrier and lock the gun up. Just had to remove a small amount of materiel to fix it but it happens.
RickedRoss Posted July 31, 2017 Author Report Posted July 31, 2017 Thanks for clearing that up. 98Z5V the box says .156.
MrPaul Posted July 31, 2017 Report Posted July 31, 2017 I think we need some clarification. Just how hard do you have to pound before we consider it pounding the shiit out of it?
blue109 Posted July 31, 2017 Report Posted July 31, 2017 Every man must answer that question for himself.
survivalshop Posted July 31, 2017 Report Posted July 31, 2017 There are some kits out there with over sized Pins for well worn Lowers or its a Typo error .

DNP Posted August 1, 2017 Report Posted August 1, 2017 A quick Google search shows a handful of options for .156 "anti walk" trigger pins.

DNP Posted August 2, 2017 Report Posted August 2, 2017 All I'm saying is there are companies making them that size on purpose. I guess you'll need a BFH for the process

I guess you'll need a BFH for the process Some manufacturers make loose Pin Holes or they get loose with wear from walking . Usually ya just get over sized pins , but the whole FCG , never seen it till now , could also be someones idea of a proprietary components , ya never know . Edited August 2, 2017 by survivalshop
Viper Posted April 13, 2021 Report Posted April 13, 2021 (edited) Isn’t 0.172 the spec for the large Colt pins? sorry, just noticed the age of this post. Edited April 13, 2021 by Viper

No, 0.169" is the Colt Large Pin receivers. They're the only ones that ever did this, too. Trust Bill Geissele for this information. https://geissele.com/colt-rifle-users-guide
