Picture borrowed from the web (but I actually have one of this trigger set).
Check your hammer if it looks like this in my picture, Colt low mass hammer type II with notch, nickle finish, or type I without the notch.
These are the match trigger set they installed on Colt models CR6724/ CR6720 Colt Accurized Rifles and other models that they upgraded the triggers.
Usually breaks at a smooth 6 pounds, if yours have this it's better than the standard semi auto triggers.
| Zach V (Geissele Automatics) Nov 9, 2021, 10:09 AM EST Good morning Mr. Hammers, Yes, it could very well be a rifle-length gas system; however, many AR15s are actually carbine/mid-length gas systems despite being "rifles". I simply wanted to make sure I had all the information before offering a recommendation.  Yes, the H1 would likely be the best bet. With .223 ammunition, the weights may vary from our chart, as that chart is based on 556 NATO pressured ammo (higher pressure). Generally, with 223, you'll want to go lighter for the buffer weight (since there is less pressure which means less gas to push the buffer). I've attached a chart below to help you adjust your buffer weight based on your ejection angle. Keep a close eye on the angle, or have a spotter help you, to fully dial in your buffer system. And again, this chart is a rule of thumb designed for 556 NATO, so .223 usage may causes some changes. Let me know if you have any other questions! Thank you, Zach Thanks Saws in Idaho |
Would the Super 42 Rifle Length Spring work better than the spring that came with the Super 42 Braided Wire Buffer Spring and Buffer Combo, H1 that I purchased from Optics Planet?
NOTE: The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions, a special rifle length Super-42 is available on our website. We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.
If it is a 20" Barrel, Would it not be a Rifle gas system? Would you recommend a Super 42 Braided Wire Buffer Spring and Buffer Combo, H1?
