    Very nice kit

    Posted by Astag Izgud on 7th Jul 2021

    The kit is great quality and everything fit properly. All went into the lower without any issues. All worked very well.

    I wish we could customize the trigger type, grip and trigger guard.

    Can't Have Enough

    You really can't have enough spares, even if you don't ever need them, you'll know someone who does.
    Picked up the kit without the trigger group, just in case I decide to drop in a different setup in it. I'd love to see bolts in stock for 5.56 and not just BCG assembly.

    Keep up the great work Stag Arms!

    LPK Minus Trigger Group

    Posted by JG32 on 25th Mar 2021

    This was a very good LPK. I've had some bad ones with parts out of spec or faulty but Stag has never let me down. My first AR is a Stag and I'll keep coming back for the good value and consistency of their parts.

    All the items I needed

    This is a great kit for those building an AR. It has all the pieces necessary if you are using a different trigger assembly as I was. I do wish they had an option to include an Ambi-Safety with a kit like this but what is included all fitted and functioned perfectly. Great cost and great products. As always from Stag Arms.
