    Did exactly as expected. Perfect fit and finish. All three weighed exactly the same. Would certainly purchase again for my next AR 15 build.

    Perfect one-for-one replacements in my stock rifle buffer. Cylinder to cylinder weight variation is extremely low.

    AR-15 Tungsten Buffer Weights

    Posted by Bib Bore on Jun 10th 2019

    These weights are just what one needs to tune a standard buffer into slower opening and softer recoiling HB, 2HB, or 3 HB. One set of three tungsten weights allows you to replace the internal steel weights with one to three tungsten weights tuning the buffer to your needs perfectly, all at a fraction of the cost of buying three separate buffers. Buying a HB, 2 HB, and 3 HB buffer can easily cost you $80 to $100, depending on from who you buy, but one set of these weights allows you to get the buffer weight you need for less than $30. How can one argue with that unless you are so inept with tools that you cannot change your own buffer internals. In that case, maybe it's best you buy factory made heavy buffers. HINTS: Mark polymer buffer end and body with a Sharpie making witness marks. The holes often do not line up if you put it back together 180* off. Drive out the roll pin with a roll pin punch. Using a new set of QUALITY side cutting pliers, grip the polymer buffer and wiggle it out of the body. A set of used pliers with worn gripping surface will only chew up the polymer buffer. I keep a new set of Kleins to be used expressly for this use. Change out the internals. Put some light grease or oil on the polymer buffer and slide it back together, aligning the witness marks you made. Use a punch to slide through the buffer and body to make sure the holes are aligned on both sides. Use a roll pin starter to start the roll pin back into the hole in the body and finish with a roll pin punch or you can even squeeze the pin back in with a bench vice, then tap the pin flush with the body with a brass hammer. Do not go bat-crap crazy with the vice or hammer and damage the body. You get no points for proving how much hair you have on your chest.

    The weights weigh the stated amount, are the correct size to fit in a buffer, and are competitively priced.

    These weights are just what I was looking for. I plan on using these to convert standard carbine buffers to the H1 style buffers. The weights where nicely packaged and over all look very nice. Once I covert my first buffer I will know if they will do what I want.

    Quality, Fast & Great value!

    These are made very precisely; beautiful finishing, consistent, and are really priced VERY reasonably. They're now my go-to source if I need to customize a buffer weight. Why buy a whole buffer when you can customize yours for a lot less? The turn-around time is phenomenal.
