What Makes Geissele Super Semi-Automatic Enhanced Large Pin Stand Out?
The Geissele Super Semi-Automatic Enhanced Large Pin (SSA-E LP) trigger from Geissele Automatics isn’t just another trigger; it’s a precision instrument designed for enhanced control and accuracy in large pin AR-15 platforms. For those unfamiliar, “large pin” refers to Colt rifles manufactured in the late 1990s and early 2000s which use a larger diameter hammer and trigger pin. This trigger aims to provide the same high-performance feel as the standard SSA-E, but tailored specifically for these platforms, ensuring a crisp, clean break and a consistent pull.
I needed to upgrade the gritty, inconsistent trigger on my older Colt AR-15, which has the large pin configuration. I was searching for a trigger that offered a significant improvement in feel and precision for both target shooting and potential tactical applications.
Upon unboxing, the Geissele SSA-E LP immediately impressed me with its robust construction and clean machining. The components felt substantial and well-made, hinting at the precision engineering within.
Compared to other triggers on the market, such as the standard mil-spec trigger or even some aftermarket options from other brands, the Geissele promised a lighter, crisper pull. I specifically chose the Geissele due to its reputation for reliability, consistency, and overall superior performance in the AR-15 platform.
My first impression was excitement tinged with a bit of anticipation. I knew Geissele had a stellar reputation, and I was eager to see if the SSA-E LP lived up to the hype and transformed my rifle’s shooting experience.
Real-World Testing: Putting Geissele Super Semi-Automatic Enhanced Large Pin to the Test
First Use Experience
I installed the Geissele Super Semi-Automatic Enhanced Large Pin trigger in my Colt AR-15 and immediately headed to my local outdoor shooting range. The weather was clear and dry, offering ideal conditions for testing the trigger’s performance.
The difference in trigger feel was immediately noticeable, the take-up was smooth, and the break was incredibly crisp and clean. The light trigger pull greatly enhanced my accuracy and allowed for faster follow-up shots.
The installation was straightforward, although I did need to ensure proper pin alignment due to the large pin design. I experienced no issues with functionality during my first range session, which instilled confidence in the trigger’s reliability.
Extended Use & Reliability
After several months of regular use in various range sessions and even a couple of training courses, the Geissele SSA-E LP has proven to be exceptionally reliable. There are no signs of any significant wear or tear, and the trigger pull remains consistent.
The trigger requires minimal maintenance, with only occasional cleaning and lubrication necessary to keep it functioning optimally. It far outperforms the original mil-spec trigger, offering a dramatically improved shooting experience.
Compared to other triggers I’ve used in the past, including some single-stage match triggers, the Geissele SSA-E LP strikes an excellent balance between precision and practicality. Its two-stage design offers enhanced control without sacrificing speed.
