Strike Industries Enhanced Lower Receiver Parts Kit - No Pistol Grip
The Strike Industries Enhanced Lower parts kit offers a convenient upgrade package for the AR-15. This kit includes enhanced versions of the bolt catch, magazine catch, magazine catch button, and pivot/ takedown pins. Also included are the SI selector lever, SI selector end plate, and SI 60-90° 3-in-1 selector shaft. Just add your favorite pistol grip, trigger guard, and stock kit and you will have everything you need to complete your lower receiver build.
The MIL-SPEC fire control group consists of an investment cast trigger and hammer, both CNC machined, heat treated, phosphated, and precision ground. Longitudinally ground and polished sear engagement surfaces combined with a precision cut sear angle create a vastly improved trigger feel which offers a consistently crisp 4.5 to 5.5 lb pull.
NOTE: This kit does not include a grip or trigger guard.

Ratings & Reviews
good kit but sears are not polished
by gary -
i think this is a good parts kit especially for the money as it has several parts that would cost more if you upgraded later. however neither the trigger sear or the hammer sear was polished and the trigger sear had some marks on it where it had been banging against the hammer during shipping. not a big deal for me as i already have hard arkansas stones and have done several triggers before. six swipes on the hammer and it was done but the trigger took several dozen to get cleaned up. i am going to add an odin extended mag release and a sear engagement adjustment screw especially since the grip screw isnt in this kit anyway. i would buy this kit again.
No issues, a great kit.

No issues, a great kit. Much more finished and polished than other similarly priced kits, and it comes with the SI Enhanced pins so that's a win. Decent trigger, ambi safety, you can't go wrong.
Looks, fits, feels wonderful.
This kit looks and fits great on my Sharps Bros. lower. The ambi safety selector "clicks" into both positions firmly. The pivot & takedown pins are very secure & slide out w/ appropriate force. The trigger squeeze is a true 4-4.5 lbs, very smooth w/ good reset. Honestly everything about this kit fit great and adds a very sleek, custom look to the rifle. Will be using again on future builds. I experienced none of the issues other reviewers have posted, maybe it's their lower.
Good value but needs some work.
Good value but needs some improvements. Overall the look and value of the kit is great, however the trigger, safety and front take down need some work. For an "enhanced" kit the safety feels a bit sloppy, some wiggle in there and not as positive of a "click" as I'm used to. The front Takedown pin is the only one I've ever had to need a punch to move it. Granted these are sometime stiff but I need a punch and a hammer to get it moving. And lastly the trigger, there's a bit of play and just doesn't feel the best. So I would recommended this kit WITHOUT the fire controls, buy a separate trigger, the other two things are not deal breakers.
Great little kit, but could use some improvements

Decent parts kit, most everything fit well and moves smoothly when installed with a little greasing. My only gripes are with the sizing of some of the pieces; the mag release has gaps around it in the receiver, the safety selector has a few mm of play back and forth (fixed when the detent is in) and the "enhanced" bolt catch DOES NOT fit a BAD lever (what the hell, SI!) and will not fit it even with some liberal grinding down. Now I have to run to the local shop and pick up another bolt catch and a punch to knock this one out. Also be warned "No Pistol Grip" means "not even the screw to install a pistol grip" so it will leave you with 2 things you need to get from the local shop if you're building from scratch - since I consider a BAD lever a must. Would be 5 stars all the way if not for the bolt catch issue and lack of a screw for your grip, of course service from PA was 6 stars and then some!
BEST LOWER PARTS KIT
by Christian -
Best Lower Parts Kit you can get for your money. Pair their trigger with a reduced power JP springs and you have yourself a well upgraded mil-spec Trigger. Ordered around 4pm and almost immediately got an email with shipping info. Unbelievable service from the staff at PA. Bravo Zulu.
Great value, wonderful trigger
by MarkH -
Enhanced parts in this kit at a great value. The thing that surprises me the most is how good the trigger is out of the box!
Great price, great parts, greater Customer service

I ordered these parts and someone had removed them during transit. One 15 minute phone call and the wonderful people in customer service quickly shipped me a replacement, no muss, no fuss. You will have my business for many more purchases. Thanks guys!
<br>These parts area great and I have used them for several builds and will continue to do so. They fit perfectly, feel great, and are worth the money.
