    Had one show up today. Here it is (left) along side a mil-spec. Size difference is observable though not immediately obvious. Spring it comes with is a hoss.

    RBF has done rather well for us. The stainless steel used is a super high quality Swiss SS. RBF is vacuum heat treated. The material, construction (milled from bar stock with Swiss machines) and heat treat are all costly, and yet RBF is still reasonably priced.

    We do have to raise the price a bit though, but we might include the springs with RBF then as well.

    I just installed one of these in my lower and I am impressed. I like it.

    Please pardon the (very) crappy cell phone pic, it didn't enlarge well. But ... glad I bought a few. This from a New Frontier Armory C45. Their AR45 platform.

    Geez! That's crazy there. Maybe you should save that part or send it to somebody to test if it was out of spec or not. If it's in spec that would make me wonder about that firearm.

    It's tough for something to be "in spec" when there isn't any set specification for the AR45.

    The buffer retainer is an interchangeable part on the two platforms isn't it?

    I’d assume so Alamo.

    Looks like he’s having a similar problem like I recently posted. But worse.

    How’s the front of the buffer look?

    Gotta be chewed up if that pin is so bent.

    The retainer may be interchangeable, but the platform isn't. Just because something works in a "spec'ed" M4 doesn't mean it works in any other configuration of an AR-15, let alone a PCC-type weapon. Just look at FCG pin wear/breakage on Colt 6951s (and the like).

    Actually, the front of the buffer is only showing what I would consider normal wear for the number of rounds fired, just a couple of small scars. IMHO, this was just a poorly made retainer, it happens.

    The tit looks too big. That'll get it knocked over.

    There's a lot of width/space on the channel, or groove under the carrier for the buffer retainer's tip. Since we wanted to keep the tip round, the size could only be increased to 10% larger in diameter.

    The HK type rectangular tip works fine on HK lowers where it's pinned, but on a lower that doesn't have the pinned buffer retainer, one would have to take the chances and hope the RE and lower combination would produce a timing that will not only adequately cover the buffer's retainer, but the lip of the RE should ideally come up and bottom out against the rectangular tip itself, to prevent it from rotating.

    Such problem doesn't exist for a round buffer retainer tip that requires no timing. 10% isn't a lot of increase, a rectangular shaped tip would be stronger by virtue of simply having more material, but it's a solution that might introduce a problem of its own, so it was looked at, then quickly abandoned as a possible design for RBF.
