Description

The BKF M4 MOD-0 Stripped Upper Receiver is a step up from our regular BKF-15 stripped uppers. The M4 MOD-0 uppers are held to tighter tolerances, Dry film lubed and tight fitting when paired with our M4 MOD-0 Lowers. Forged from 7075-T6 aluminum, this stripped upper is precision machined to mil-spec M16/M4 specifications and features M4 feedramps. Match this upper with one of our M4 MOD-0 lower receivers for a solid and dependable fit. This upper receiver has laser engraved T-Marks. (The Inside Diameter for the barrel extension is slightly undersized for a tighter fit to the barrel and will produce a more accurate rifle. Please note: you may need to use a heat gun or hair dryer to warm up threaded bore of receiver and freeze your barrel if your barrel extension is too tight.)

Features:

  • M4 Feedramps
  • 7075-T6 aluminum
  • .250 takedown pin holes
  • Machined .9980″ barrel extension
  • Machined .4960″ Lugs
  • Laser engraved T-marks

      Quality upper receiver at a great price.

    5. Tony J. (verified owner) –

      I started off by ordering little small things from BKings firearms to see how quickly they shipped and the level of service. When I felt comfortable about ordering larger ticket items I was not disappointed. I received my 3x Cerakoted Receiver sets and I am very happy with the product and would not hesitate to let my friends know where they should order these items from.
      thank you

      Barrel fit without any heat, but it is decently snug. Only gave 4 stars because it had a little scratch.

      Your web site is something to be desired… lol but your products are excellent delivery timely never have I ever had an issue or a bad product from Bkings…Thank you for your service to this country and a continued service to law biding citizens who chose to exercise their 2A rights that shall not be infringed. Front and center .because it may be 2nd but it’s the most important.
      Thank you Dan,

      Seems like a decent stripped upper

    33. Ethon Stafford (verified owner) –

    34. Gabriel (verified owner) –

      so far very happy with this upper nothing bad

    35. JAKE (verified owner) –

      I’m giving this a perfect rating, but with a caveat; The first couple I ordered had a “U” forge code, all of them were loser tolerance than the milspec receivers I ordered around the same time. They weren’t out of spec or unusable, they just weren’t the tight tolerance they were supposed to be. BKFs customer service is excellent, and I brought up the issue. They told me that they had addressed the issue. Sure enough the next ones I ordered were as advertised and couldn’t be happier. It’s like getting a BCM upper for 1/3 the cost. As long as all future receivers are like this, they get a 5 star.

      These mod 0 uppers have the same tolerances as BCM uppers. thermal fitment = good to go!

      First upper recover I bought from BKF. Paired it with a bkf barrel and the fitting was TIGHT. Love it. Usually hard to get that kind of fitment when mixing and matching brands. Next build is coming from bkf as well. Never disappointed
