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

Love these lights! Switch and wiring harness is really nice! Lights aren’t too bright but definitely add a nice touch to a motorcycle.

Leaky but still working
Color: White Combo Beam, Color: White Combo Beam
I want to love them but they have started leaking after about 2 weeks. They are very bright, really nice throw, I like the low high function. One very mild desert rain in Utah - the next day one of the 2 is all fogged up. Maybe I just got a bad one? Install was a breeze, the unit is all in one with button switches included. I find the water leak to be pretty unacceptable this early on though, pretty disappointed ☹️

THE BEST SPEAKERS
Size: Pair, Size: Pair
These speakers are the best sounding bookshelf speakers i ever saw or heard. The sound from them is clear even from a cheap crosley suitcase record player and the bass is just awesome because you can actually hear it and it ties my songs together when i can actually hear the baseline. They work extremely well independent of a separate subwoofer because the bass is very strong! Another point of praise is that the decibel count is very high at 93 which means on very low power they perform loudly. Even on low volume from my Aiyima A07 Premium amplifier, they can be heard throughout my house. They look so cool and appear to be very high quality build and strength. They can be used for whatever you want (provided your amp is compliant) they're super easy to set up because all you do you just attach the sticky rubber feet on the bottoms and the grilles are magnetic for whatever aesthetics youre going for. Definitely worth the money (i bought them on sale for $230) very top notch speakers!

Very good speakers
Size: Pair
The r51ms are used to compliment my klipsch rp500m speakers and a 12 inch subwoofer in a large living room. By placing the r51m speakers to the outside walls , and the rp500m speakers to the interior, closer to the amplifier, and with the subwoofer set on deep bass only at just enough volume to barely compliment the sound, the large living room is more than sufficiently covered with at least true high fi quality sound, if not true budget audiophile sound. My entire 2.1 system is all klipsch. That's how I want it. I am using them with a high powered tube amplifier, so presence and clarity is awesome. Placement is critical. I was initially disappointed until I switched the r51ms to the spread to the outside walls position, and the rp500ms to the interior, closer to the amplifier. The difference was remarkable. The 2 different klipsch speakers, ie one a rp and the other a r series blend together perfectly with no clash whatsoever because of somewhat more refined sound on the rp500m speakers. The rp500m speakers do sound higher end , but they are supposed to, but with the speakers as outer r51m and inner rp500m, and the klipsch subwoofer at deep bass with just a touch of volume the result is sound of such quality that I can honestly say I can be content and satisfied with it. I can say my system is complete, and no further improvement, upgrades are needed. Tower speakers as primaries are not necessary because of the high quality of sound and the high sensitivity of the 4 klipsch bookshelf speakers and klipsch subwoofer. This saves me money during this rapid inflation period of time. I could easily say that what I have sounds more than good enough to be satisfied and content with without any desire to upgrade further at this point. Shipping speed was excellent via Amazon itself, and the box and speakers arrived in handled with care and new condition. I am not disappointed at all now that the r51m speakers are the outside speakers, spread apart from corner wall to wall to compliment the interior placements of my rp500m speakers by klipsch. Im all klipsch here and I love it. 5 stars categorically. As previously stated, I see no need for primary tower speakers, even in a large living room, and that equals high quality sound and savings of money at the same time. I recommend these speakers. They do more than just do sound quality wise.
