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

  • Buffer Retainer - large hollow barrel with small pin protruding from the top

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape. My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days. That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.
