Smooth, Even Trigger Pull, Precise Letoff; Easy Installation
Easy-to-fit replacement for factory trigger is fully adjustable for engagement and overtravel, and is available with pull weight as light as 3.5 lbs. Redesigned sear geometry and advanced metallurgy result in a precision-ground sear edge that delivers a precise, consistent letoff and prevents the kind of wear that causes doubling and other problems. Extremely short reset enables fast follow-up shots, a critical advantage on tactical and competition rifles. Machined to exceptionally tight tolerances from hardened steel, and installs in minutes with no permanent alterations to the rifle. Lets you upgrade an AR-15 or an AR-style .308 rifle that uses an AR-15 trigger, while keeping your current hammer and pins. Disconnector spring, engagement screw, and overtravel screw are already installed; also includes disconnector, trigger return spring, hammer spring, and .050" hex key. Use with J.P. Enterprises Speed Hammer (available separately) for best performance. Comes with a standard weight hammer spring, for a trigger pull of between 3 and 3.5 lbs.—perfect for competition and recreational shooting—plus a “tactical” spring that gives a 3.5 to 4 lb. for applications demanding a high level of ignition reliability, including police/military use, mil-spec ammunition with hard primers, and in AR-style .308 rifles. JPFC-1 fits rifles with standard .154" diameter trigger/hammer pin holes.
SPECS: Steel, Parkerized finish. Models for rifles with either .154" (military and current aftermarket) or .169" (current Colt) diameter trigger pins. Measure your pins and select the correct kit. Includes complete instructions and a CD-ROM with 35-minute video showing step-by-step installation.

This is the best trigger out there(03/09/2009)
This has been a great trigger in my varmit gun. very reliable. If you are not educated o the working of an AR trigger it may take longer to install but there are very good instructions included.
Hot set-up, Fun to install(14/01/2010)
I purchased this product and also the JP Ent. speed (low mass) hammer and I thouroughly enjoyed the installation process. I took my time and fitted everything by hand with an EZ Lap diamond hone (available from Brownell's). A file is pretty much useless since the parts are hardened throughout and a file will just glide right along the surfaces without much cutting action. I stayed away from using a grinder or belt sander because I've read other customer reviews and others have experienced ruining their parts by over doing it and I am pretty good at shaping things by hand and you can get a very precise and uniform finished surface if you go slow and carefully and continue to check and recheck fitment by assembling and disassembling and reassembling the trigger assembly. I honed the diconnector hook and removed about .0166" from the top of the safety engagement pad on the rear of the trigger. You can also purchase a JP Enterprises safety so you don't have to do any fitting for the selector lever/safety. It took me about 2 and a half hours but like I said I went slowly and very carefully. When I was finished I went from a very rough and long 6 1/2 pound pull to a very light, smooth and crisp pull measuring just a hair over 3 lbs. There is zero over travel and almost unoticeable trigger let off or sear disengagement. I plan on buying another one and installing on one of my otther AR's. I recommend this product to anyone who desires to dramatically improve their original trigger assy.
Qualiy Trigger Assy.(16/01/2010)
Took my time installing. I also used their low mass Speed Hammer in with the installation. Had no problems when following instructions. Video not that hot. Made all the fitments using an EZ Lap Diamond hone/stone. Parts are hardened throughout. Resulted in a trigger with virtually no overtravel and a crisp smooth trigger let off/ disengagement. Takes a little time to instal with some assembling, Checking fit and re assembling but well worth the effort. I am satisfied and will probably buy another one for another AR. I would definately recommend this product to anyone who takes pride in their AR-15.
Great upgrade(17/04/2010)
I bought an R-25 and it had a notoriously bad trigger. I took my time and followed the directions. I used 600 sand paper and a flat surface to fit the disconnector. Worked like a charm. Trigger is AMAZING.
Nice Feel(27/11/2010)
Good instructions & video mine fit very well did not have to time or fit disconector. I did have to do a little fitting on the saftey. With a little mechanical ability its not hard. just follow the directions and use the video for clarification.
So Long Creep(06/12/2010)
Read the book, saw the movie. Saw the movie, read the book. This was installed in a R-25 308. I used the orginal hammer and hammer spring per instructions for reliable primer ignition. The original R-25 trigger pull average (10 reps.) was 4.85 lbs. The creep could have been measured in inches but my percepto meter was tainted by the unmeasureable length of time it took to consistently drop the hammer. What I really wanted out of this installation was minimising the creep. My expectation met reality. My trigger pull average after installation is 3.9 lbs. (10 reps.) I have a wolf extra power hammer spring in case my primers are not dented to delight. I have three other black rifles that now require a similar upgrade. The JP trigger design for the single stage release will make a better shooter out of everyone who uses it. I did not use my belt sander on the disconnector hook. I used a washita stone to square and polish about four-thousandths off the original dimension at the disconnectors hooked tip.
Love this trigger(30/08/2011)
I prefer single stage triggers over two stage triggers due to a lot of time on bolt guns. This setup makes your AR trigger feel more like a well adjusted Rem 700 trigger. I first tried it because at the time there weren't any other single stage options out there for the AR, and I've never looked back. Using the mil-spec hammer spring this trigger usually breaks right around the 4 lb mark. I've installed almost a dozen of these now, and installing it right and getting it tuned is probably about a 20-30 minute job. It will require some grinding on the back of the trigger for safety engagement, and occasionally require fitting the disconnector as well. Provides adjustment for sear engagement and over travel. Dropped to 4 stars for setup and tuning time, and it will require loctite (red) which is not provided. Great trigger overall, I use it on all my AR's.
Great trigger(31/12/2011)
Great trigger. Set it to the pull weight you and. Put in on LMT at 4 pounds and could not be happier.
Great trigger(06/03/2012)
Used the two yellow springs, carefully followed the instructions and ended up with a lovely 4lb single stage trigger, and that was with using a std hammer.
Outstanding trigger system(03/06/2012)
I have installed several of these triggers and they are excellent. I never cared for the two stage triggers, and this in my opinion is the best single stage trigger out there. I install them with the JP speed hammer and kns pins, and it is a winner. Breaks clean and smooth. You will love it, don't hesitate to purchase.
Total reject, could not be fitted.(04/11/2012)
Parts included with kit did not match the instructions provided with the kit. Trigger part would not fit or function at all in my receiver, nor could hammer be made to disengage at all. Proper adjustment, assuming parts did install to start with, requires multiple insertion and removal of parts into receiver, and hand-filing of engagement surfaces by repeated trials.
Excellant single stage trigger(08/03/2013)
Installed in my AR Tactical build replacing DPMS 2 stage trigger.Prior trigger pull was about 8 lbs.After installing using yellow springs,actually ended up with just below a 3 lb trigger pull with no creep,clean break,very short over travel and fast reset.Took alot of hand fitting with hand files but well worth the time and effort.No failures to fire or locked up trigger problems.Very Happy with the results.Cut my group size's to half inch at 100 yards with a 16 inch 1-9 barrel.
Excellent Trigger, but....(24/07/2013)
This is by far the nicest feeling trigger I have ever used, but.... be prepared to do a little gunsmithing. If you dont have basic gunsmith skills and tools buy the JP EZ trigger kit that retails for around 269.00-289.00$, that kit is just like this one except for that you can just drop the EZ kit in without any gunsmithing. Other than that, 100% great buy
Works fine in S&W 15-22(25/09/2013)
I got one of these years ago to put in my AR-15 for 'service rifle' matches so I was familiar with what it would take to install this trigger. It now comes with a nice video showing how to adjust it and how to adjust the factory hammer.
I was glad to find that function is 100% on both SV and HV .22 ammo. The trigger pull is a vast improvement over the factory trigger.
My kit did not contain Loctite even though the instructions said it was included. You will need a stone or some sort of accurate grinder to make the hammer adjustment.
smooth trigger(29/04/2014)
Bought this for long range shooting and couldn't be happier with the results. Had no problems with installation or removing it and putting it in different lowers with the same great results. Make sure to use the grease on the sear engagement surfaces and DO NOT FILE Them!
SIMPLY EXCELLENT(28/10/2014)
Amazing improvement over the trigger my Sig 716 came with.
Very crisp with short reset but not very light with the included red spring which is to be used in the AR10 platform.
Took me about two hours (I had dinner while waiting for the loctite to set) to install it following the detailed instructions. You'll need a stone, high strength loctite, brake cleaner, a vise and a lot of patience as you'll have to remove and re-install the parts several times to make sure you do not remove too much material.
I am very satisfied with this purchase.
great trigger but req fitting(14/11/2014)
I have used 2 of these with 3-4 # pull, no creep, no movement with safety engaged. This is not a drop-in trigger as it requires fitting for the safety to function but the results were excellent.
wont fit Tactical Solutions AR-22(12/05/2015)
I have installed about 10 of these triggers over the years and had no problems.. They are on all of my
hunting guns in different configurations and different manufacturers including DPMS, PWA, Cav Arms and Stag Arms with no problems. I just attempted to install one in a Tactical Solutions .22 lower and it will not work without milling of the lower receiver. Great trigger highly recommended..
Excellent(11/11/2015)
I have installed a bunch of these over the years. I couldn't be happier. These have to be fitted properly. The instructions are very good. You need a stone or file . The Safety wont function until The back of the trigger is filed down. It's the most time consuming step. You do a little at a time. Reinstall check safety function. Pull back out file some more. The fit you are looking for is the safety will actually make contact with the part you have filed, but is able to fully engage. When the Safety is fully engaged the Trigger should have zero movement, because the safety is resting against it. This is necessary, because you have adjusted virtually all of the take-up out of this Trigger if it was adjusted properly.
Best trigger ever(18/04/2017)
This is the best trigger ever at about 1/3 of the price of the hive mind's "best" triggers, in a rugged and essentially mil-spec trigger. I've set mine for 3½-4 lbs break because I think a very light pull trigger is dangerous, and my total trigger travel is set at 2 mm. I can't feel any take-up due to the minimum sear engagement and sear geometry, and the trigger always breaks crisply with no hint that it's about to happen even though I know it will. It does take some care in installation and I found that honing the trigger's rear surface for safety engagement was best performed with a diamond bench stone for quick but smooth cutting and calipers to measure as I cut so that I didn't overshoot, because at this minimum sear engagement no sear movement on safe is tolerable. Nearing the safety engagement point, I took no more than .002" off between each trial. No polishing of the sear or notch is needed, which might remove the case hardening and shorten the operational life. I enjoyed the installation process and the final result was more than worth it.
