wfv56 Posted May 1, 2009 Share Posted May 1, 2009 A friend would like me to put a giessle trigger in his lower. What pin size do the latest production m4 clone's from Colt have? Do the still use the sear block? Thanks Bill Link to comment Share on other sites More sharing options...
ShooterSteve Posted May 1, 2009 Share Posted May 1, 2009 My Colt H-bar has the larger pins in it. I believe they are .171 or thereabouts. That may not be exact, so someone may step up and correct me on that measurements. I had a Jard trigger in mine that I lilked a bunch. The only reason I took the trigger out was to return the rifle to original condition to sell. So I have a Jard for a large pin colt if anyone needs one. Will include a free set of brand new JP antiwalk pins with it also. . Oh yea, the Colt H-bar, A3 flat top, Competition match target, 20" with a factory comp is also for sale. I'm after a JP ctr02 upper, so I'd also trade this whole rifle for a fairly new condition JP upper. I know I got way off on thread drift, sorry about that. If you haven't purchased the Giessel and are interested in a good deal on a Jard just give me a shout. Link to comment Share on other sites More sharing options...
uscbigdawg Posted May 1, 2009 Share Posted May 1, 2009 Yep. .169" pin (a.k.a. large pin). He'd be better off with a JP trigger. Rich Link to comment Share on other sites More sharing options...
wfv56 Posted May 1, 2009 Author Share Posted May 1, 2009 Tell me about a JP trigger. As a highpower goy this is not a trigger I know. Thanks Bill Link to comment Share on other sites More sharing options...
John Dunn Posted May 2, 2009 Share Posted May 2, 2009 I'd measure the pins before ordering, I just picked up a Colt 6940 with the "Restricted Law Enforcement" markings and it is small pin. Link to comment Share on other sites More sharing options...
Pat Miles Posted May 2, 2009 Share Posted May 2, 2009 Take the time to measure the pins in your friends gun before ordering the trigger. Then you KNOW what you are working with and you'll get the right trigger for sure. CYa, Pat Link to comment Share on other sites More sharing options...
ShooterSteve Posted May 2, 2009 Share Posted May 2, 2009 JP makes a great trigger. It is like all of their stuff -top notch. You can get a regular trigger and install it, or get a drop in unit which is self contained. Just slide the entire unit in, and push the pins in, and you should be good to go. I am surprised that more high power shooters don't shoot a trigger like the JP, but on the other hand, I haven't shot high power, so maybe I shouldn't be saying what they should use. I believe the web site is www.jprifles.com . Link to comment Share on other sites More sharing options...
jobob Posted May 2, 2009 Share Posted May 2, 2009 I recently installed a JP trigger in my DPMS 308 lower. Just the trigger, not the kit with a new hammer. I was pleasantly surprised how good the trigger came out using the factory hammer. Smooth and crisp! Link to comment Share on other sites More sharing options...
wfv56 Posted May 6, 2009 Author Share Posted May 6, 2009 Thanks for the help. Friend lives 100 miles away and wants to come up for a install. He has no tools to measure. As a result I hoped to find in advance if Colt still used big pins and the sear block to save him a possibly wasted trip. Thanks Bill Link to comment Share on other sites More sharing options...
SPR1 Posted May 29, 2009 Share Posted May 29, 2009 Unless it is a VERY recent LEO Colt, like the 6920/6940, it will be large pin. The 6920's just started shipping with small pins. I would find a way to measure them first. The Geissele will not fit with a sear block (but I believe it will with the web version). He can just open the receivers to see whether it is a web or a block. Link to comment Share on other sites More sharing options...
spd522 Posted May 30, 2009 Share Posted May 30, 2009 My Colt Match HBar has the large pins. I installed the Colt factory competition trigger/hammer and it is actually quite nice. It's drop in. My SP1 has small pins. It has a Jard in it. The Jard is much lighter but I thought it was kind of a PITA to adjust right. The rest of my ARs, including 9mm and DPMS 308 all have JP. They are simple to install and just work great. I don't think they can be beat, especially for the price. Craig Link to comment Share on other sites More sharing options...
patrickbeijer Posted May 30, 2009 Share Posted May 30, 2009 The Colts HBar Target with the large front pivot pin have the .154 triggerpins the one with mill spec pivot pin has the large triggerpins .169 With Colt they have always one or the other not mill spec in the pins Link to comment Share on other sites More sharing options...
HSMITH Posted May 30, 2009 Share Posted May 30, 2009 A well adjusted Jewell is the best I have tried in a Colt to this day. Link to comment Share on other sites More sharing options...
SPR1 Posted May 31, 2009 Share Posted May 31, 2009 I believe the Jewell has a slower lock time than stock, which is really slow already. Link to comment Share on other sites More sharing options...
HSMITH Posted May 31, 2009 Share Posted May 31, 2009 Might be so, but it was a world easier to shoot than a well adjusted JP. Link to comment Share on other sites More sharing options...
