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
  • Takedown Pin Detent - same as pivot detent; both sides usually rounded
  • Selector Detent - one end is flat, the other pointed/semi-conical
  • Buffer Retainer - large hollow barrel with small pin protruding from the top

Nice wedge pillow but not enough...
Color: Cool Grey, Size: 24x24x12 inch
It came compacted and when I opened it expanded almost immediately, maybe took like 20 minutes to fully decompress. Its soft and comfortable and the cover is really nice. But it does have a strong chemical smell, which is normal for this kind of brand new memory foam, I just put it on a table with a window open near it and after maybe 24 hours the smell was almost completely gone. The problem is that I bought this to have a elevated position when sleeping but the 30° are just not enough for me. I wish it was at least 45° but I could not find any pillow with that amount of degree... it's either 30° or like 75° in the other position. At the base of the pillow there is a little ridge that is comfortable for the lower back but makes me slide down in the middle of the night so I end up almost laying flat with my neck on the base ridge. With my slim build my lumbar area gets some nice support but makes my head almost have a "fall backwards" sensation, I like having my neck have a "push-forward" position with my pillow, but when adding another pillow to try and get to a comfortable position it only makes me slide down even more... :/

Very firm and durable
Color: Cool Grey, Size: 24x24x12 inch
worked great for husbands surgery recovery. Very affordable, firmness was great, looked nice on the bed and also used it for the grandkids when they were watching a movie. Moved around with ease. Didn't use it to sleep with all night though. He could only make it half the night but that wasn't the pillows fault. It was the cast on his arm. Definitely did its purpose after surgery and the need to sit up in bed more. highly recommend

Sasstie Wedge Pillow
Color: Cool Grey, Size: 24x24x12 inch
Perfect. I used it when I was recovering from hip surgery. Relieved a lot of pain in my hip and knee at a time when I needed relief.

this pillow is huge i’m 5’8 and it’s perfect, as soon as i laid down it relived pressure in my back, i get hot fast and you can feel the cooling silk like texture, it’s weighted aswell, as soon as i opened it, it fluffed up an it’s been about 2 hours since and it’s already huge, it says 24-48 hrs to fluff up fully but idk how much bigger it could get lol it’s definitely worth the few extra dollars

I must have for pregnant women! Definitely helps sleep and comfort for sleeping!!
Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
I do love this pillow, it does take up a lot of space on my queen bed! But when I wrap my legs around the pillow, it gives me much relief on my back! It also has basically a built-in pillow so you don’t even need to use a pillow! I love that I was able to unzip the outer material and wash it! You can use it to sit up and support your back, and when the baby comes, you can use to help with feeding! sometimes I have to turn it completely on the other side if I want to turn over, it’s big!! heavy! Very soft! Not flat at all! Firmness is great! Height is great! I highly recommend! I’m also five months! i got it about 2 months ago!!
