I am totally spoiled by the Geissele trigger I bought. You should consider the Geissele SSA trigger at $145 from ADCO. You should also consider that, if you are willing to spend $150, another $100 for the match trigger just isn't that much. You will enjoy their High Speed trigger immensely. I do. |
I have read about this trigger. What is the difference between the $145 Geissele and the $279 Geissele? |
Besides the price???? and can anybody tell me about the White Oak Arms trigger? |
|
The $145 SSA Geissele is a nonadjustable while the Geissele High Speeds are adjustable. Both are great. Another significant difference is that the wait time to get an SSA is somewhere more than four months. Another good nonadjustable two stage is the LMT, which is in the same price bracket as the SSA. |
The link's been through here a few times, and it certainly seems interesting, but I've yet to see any end user feedback. |
I hate to say this but if I spend $279 for a trigger it would definitely be the Geissele. |
I'd like to see the force-displacement profile for the Geissele trigger for comparison to those shown on that web site. |
|
I would consider 2 in the price range you're looking for: 1) Single stage - JP adjustable - I have one with over 15,000 rounds on it that has not lost its adjustment 2) 2 stage - WOA tuned RRA - These are about the best in the price range you are looking for. It you want the best for everything. The Geissele is unbeatable. I have one and another on the way. If my budget would allow, I would replace ALL of my triggers with these. |
If you go to the web site link for the AR15 Gold trigger, you will see several graphs which plot the force applied to the trigger shoe (force) versus the trigger shoe movement (displacement). This type of measurement and plotting is very common for mechanical systems. The plot illustrates a very fundamental characteristic of the mechanical system. With appropriate adjustment of units, this is data forms the basis for stress-strain curves for materials. From these plots you can obtain the Young's modulus or elastic (spring) constant , the yield strength of a material, the ultimate strength of a material, etc. In systems that rotate, similar measurements are made but are displyed in units of torque-theta (angle). To make these measurements you need a suitable force gage and a sensitive suitable way to measure movement. In the case of the trigger measurements, you can see the pull weight for the first stage, the amount of travel before th esecond stage kicks in, the pull weight for the second stage, the amount of travel in second stage before trigger breaks (creep), the overtravel, the impulse at the end of overtravel,... If they were to make and display multiple trigger pulls, you could see the variability of the trigger, too. They could also show the lock time, if they wanted. |
|
If you look at that scan that trigger has a sear engagement of .010" which is about 2-3 times in excess the sear engagement of the Geissele Hi-Speed. From my experience the break would not be like a 'glass rod' but more spongy. To compare each you would need to use the same instrument with properly adjusted triggers. Where is the lock time measurement? That data acquisition system should be able to determine it. |
I thank everybody for giving me so many options but I think that bsp212 is right, for a 2 stage trigger in my price range, I don't think that I will be able to beat the WOA trigger. Thanks again everybody. |
