RBF (Reinforced Buffer retainer, Forward Controls) is a strengthened AR buffer retainer machined with Swiss machines from 17-4 stainless steel bar stock, and heat treated to H900 hardness.  RBF features a reinforced tip that is 10% larger (0.102) than TDP spec (0.093).  We don't want RBF to be timed (as the case with a rectangular tip), so RBF retains the TDP buffer retainer's versatile round tip, and is installed per TM instructions.  10% is as much as we could increase before encountering receiver extension timing incompatibilities.

When all the systems in an AR function properly, one could argue that a reinforced buffer retainer isn't necessary.  We agree, except mix and match parts from different manufacturers and their varying adherence to TDP specs, tolerance stacking is far from the exception.  Many of us have had this inexpensive part break and toss its tip into the lower receiver, usually in the trigger group and cause a jam.  RBF's billet construction and reinforced tip aim to mitigate this, it could be viewed as cheap insurance, even if the way we make it is anything but cheap.

RBF is a stand alone product, it's available with optional buffer retainer springs (x2).  When it comes to springs, it is our practice to include extras when they're under pressure during installation/removal, optional buffer retainer springs inclusion is no different, two springs will be included should you opt for them.

RBF is compatible with AR15/M16 milspect rifle and carbine receiver extensions, as well as Vltor A5 system receiver extensions.

NOTE:

* Always wear eye protection while handling springs under pressure, spring loaded pins and detents.

* RBF isn't a fix for out of spec lowers with incorrectly positioned buffer retainer hole.  If you detect excessive wear marks on the buffer's front face, it's advisable to warranty exchange your lower receiver. 

* Compatible with PWS Enhanced carbine receiver extension.

* Receiver extensions (REs) timing on the receiver can vary.  While the an RE can rotate past dead center (with the RE covering and retaining the buffer retainer) by 45 degrees or more on one receiver, it might only be able to do 15 degrees or less on another.  Also, different REs have different timing values.

Genius upgrade
Who would of thought of upgrading the buffer retainer, but here it is. I thought of this especially with the use of heavier springs and buffers these days to tame suppressed and overpassed guns. That little pin has to be taking a beating! This small but genius little upgrade will be going in all my lowers and give peace of mind assurance that this small but critical component will not break or wear out even when using extra power springs and heavy buffers.

Mr
I ordered these to replace the retainer pin on my AR9 since my buffer destroyed the chinesium pin that came with the folding stock adapter. I ordered this and, this is no joke, 10 minutes later a shipping label was already created. It was then dropped off at USPS within an hour and at my house, half way across the country within 3 days. The pin itself is extremely high quality and I will be putting these in the rest of my AR15s for ease of mind. He also included extra springs in my pack of 5 pins since we all know those things shoot into space any chance they get. Can't say enough good things about Forward Controls and I'm already going to tell my other 2A friends about this place.

The BEST
These go in every single build, noticeably stronger and better built! It is all the small things that add up and make the difference! Gold Standard in every build!

Thoughtful Design
There are a number of reinforced buffer retainers out there, but most of them are oblong. This version stays closer to the TDP. It should never be a problem if you have a decent BCG.
