Description

This product is 100% made in the USA! All components are quality Mil-Spec parts for completing your AR15 lower receiver. Trust in BKF for a smooth hassle free build.

ELG stands for ‘Enhanced Longitudinal Grind’. Our new lower parts kits have set the standard when it comes to out-of-the-box mil-spec performance.  At the heart of this kit stands the longitudinally-ground trigger, which is ground in-line with the direction of pull along the long axis of the trigger, and then finish-polished. This grind and polish provide two significant advantages over standard mil-spec kits: 

  • A smoother pull with reduced grittiness

  • An enhanced basis for performing a trigger job

  9. Justin Palmer (verified owner)

    Easy build. Handle is/was pretty loose. And brace will not stay or lock in place. Just slides right off. Not sure if it’s user error or what.

  17. Anonymous (verified owner)

    The SBA3 enhanced lower kit was awesome! The trigger in particular was much better than stuff at the same price range (my experience with Anderson and Critical Capabilities).

    Customer service was equally awesome! Ordered on a Sunday night, shipped out Monday morning! Highly recommend BKF and this kit!

  24. Derek (verified owner)

    Great price on a quality kit with everything needed for a pistol lower. Not really sure the ”enhanced” fcg makes too much of a difference to my fingers but it can’t hurt.

    Good deal fast shipping

  39. William (verified owner)

    Was EVERYTHING I needed to complete a dedicated pistol lower, all in one place, in one package & at a phenomenal price.
    Everything fit great & went together smoothly.
    Already looking at making another order in several days.

    My ONLY complaint is that I wish I had found BKing’s a year ago BUT blame that on Google, NOT BKing’s.

    Great piston build kit. everything i needed to finish my lower.

  45. Daniel Lewis (verified owner)

    A-ok glad I found for the price

  46. David (verified owner)

    This is probably the best deal you will find period even with a little shipping this checked all the boxes. SB brace with buffer tube kit and the lower parts kit all US made for less than $140.00 to my house. The only complaint I have is I didn’t grab a second set now I am sadly awaiting a back in stock notification. BKing’s pricing has always been solid (no it’s not always the absolute cheapest ……. but it’s well within and in this case even better and hey you’ll even get you stuff in a timely fashion)

  47. Michael Bean (verified owner)

    You guys rock…..fast shipping too

  48. Ronnie J. (verified owner)

    Excellent

  50. Ralph L. (verified owner)

    I was surprised on how quick I received my order. This was my first order with you. I was also very happy with the quality of the parts in my AR pistol lower kit. Going forward, I will be doing business with you guys in the future.

  51. Scott Summers (verified owner)

    Are you kidding me, where else will you find all these items for 130 Bucks?

    Awesome product. Great customer service.

  70. Chase Maag (verified owner)

    bought for a future build but the parts look good, maybe a small blemish on the tube but that is it

  71. Kyle H. (verified owner)

    Had everything I needed to rock n’ roll. After I assembled this kit on my lower I only needed to attach my friends assembled upper and I was shooting! The trigger creeps a little to break which some prefer. Overall a solid kit at an unbeatable price.

  72. louis tucci (verified owner)

    Extremely happy with this lower brace kit! Everything fits perfectly, and shipping was quick. I will definitely do business with BKings again soon!
