Description

The Strike Industries Enhanced AR-10 Lower Parts Kit (Builders Kit) is a convenient upgrade package for the AR10/LR308 and those looking for a complete Strike solution for their new long range builds.

This is called the Builders Kit as it includes all the essential parts needed to complete your build. It does not include a pistol grip or mil-spec trigger parts because we understand that builders may want to use a pistol grip or drop-in trigger of their own choice.

Check out our SI AR Grips available which are also great choices. We do include spare springs for mil-spec triggers in case you want to refresh your old trigger which is a better option than letting it collect dust in a random drawer.

With our Strike Enhanced Parts, you'll have a built-out lower receiver with better looking and higher functioning parts than an average LPK.

COMPATIBILITY:
-AR-10, DPMS/LR308, SR-25 lower receivers
-Aero Precision M5 lower receivers have slight generation differences. Due to generation versions and tolerances, newer gen M5 lowers fit rear takedown pin slightly better than older gen M5.

NOT COMPATIBLE:
-ArmaLite AR-10
-Some billet lower receivers due to no Mil-Spec standard
-AR-15: Bolt Catch, Bolt Catch Roll Pin, Pivot Pin and Takedown Pin are not compatible with AR-15 lower receivers

PACKAGE CONTENTS

SI ENHANCED PARTS: (11pcs)

SPRINGS: (9pcs)

  • Bolt Catch Spring - easily confused with the disconnector spring; disconnector spring is tapered though
  • Magazine Catch Spring - this is the largest coil spring in the kit
  • Pivot Pin Detent Spring - same as the takedown detent spring, so there are two in a kit
  • Takedown Pin Detent Spring - same as the pivot detent spring, so there are two in a kit
  • Selector Spring - similar to the takedown and pivot detent springs, but larger diameter; there will only be one of these
  • Buffer Retainer Spring - second largest coil type spring in the kit
  • Hammer Spring - largest of all the springs
  • Trigger Spring - the smaller of the two largest springs
  • Disconnector Spring - slightly larger than bolt-catch spring, identifiable because one end is a little bit wide than the other

PINS/DETENTS/OTHERS: (8pcs)

  • Bolt Catch Plunger - mushroom shaped pin
  • Bolt Catch Roll Pin - smaller of the two roll pins
  • Pivot Pin Detent - same as takedown detent; both sides usually rounded or semi-conical

Grille-ing Me Softly: A 30-Minute Makeover Adventure
Color: Single Slat Gloss Black, Size: 2019-2022 G20, Color: Single Slat Gloss Black, Size: 2019-2022 G20
Installing this grille was a breeze! It took me about 30 minutes, even with a minor hiccup of having to uninstall it to add the front camera panel I initially forgot. The grille feels incredibly durable, made from plastic that matches the quality of the OEM version. Plus, it gives my car a fresh, youthful look. Highly recommend for a quick and stylish upgrade!

Fit is ok
They are a definite improvement from my original 22 year old grills but they have some clear differences in quality of the chroming, if you compare oem to these side by side the oem grills look smoother. also they don't fit great at least not on my car, albeit with a bit of nudging they fit pretty close to the originals. Overall not bad for something that is a quarter of the price of the oem part
