Black anodized, Carrier cradle extentions, Detent-lock prevents tube rotation, 3 drain holes. Mil-Spec 7075-T6 aircraft aluminum Anti-tilt Buffer Tube uses "carrier cradle" extensions to ensure that the carrier is always supported by the buffer tube, even when the bolt is forward. This prevents carrier-tilt and premature wear on the buffer tube. Thusly, the buffer-detent button doubles as a lock that stops the buffer tube from rotating and becoming loose under extreme operation conditions. POF's desiging also features three (3) extra drain holes for marine environments. Replacement Compatible with All P415 and P416 rifles with 6 position buffer tube. Replacement Compatible with P308 rifles manufactured BEFORE OCTOBER 2012 that used a 6-position buffer tube! New P308 rilfes feature a 7-Position Buffer Tube that utilize the standard AR15 Carbine Buffer and .308 A2 Rifle Length spring. Refer to the first two digits of your weapon's serial number for the year. If it reads "12-", please check your rifle's adjustable stock position count before making your purchase.

Great for piston systems


I use this with my Adams Arms piston upper and it works great. So far no signs of accelerated wear.

Great buffer tube


This is one of the best Buffer Tube I've ever own.. Got yo shoot my PWS MK114.. And it ran Flawlessly.. Definitely picking up another one..

Nice anti tilt design


Works perfectly, nice tolerances. Great for use with a Piston AR upper as the extra material protects the buffer tube threads on your lower. Nice side effect is that it also keeps the buffer tube from spinning should your castle nut work loose...uh you did stake that castle nut didn't you?

Nice Tube!


Great quality piece, with excellent design and manufacturing. Interior finish is very nice and extra size tabs are great for additional support and stability.

Fastest shipping I ever saw!


Ordered Saturday at 11:50. Received Monday .. TX to NC!

This buffer tube fits ANY Mil-spec carbine. With a JP Enterprises silent buffer I didn't need a buffer detent, so it was ground flush with the tube lip for the "anti-tilt" function. I call "BS" on those saying you can't open the weapon normally. The BCG slightly eases the buffer back as I intended and sits on the lower tube lip for completely linear operation. Opens and closes effortlessly with the rear pin. Project for the wife. Months of research by a 30 year retired engineer. Over $2k parts and carbine for a $600 Ruger AR-556 (we're fans). You can't do better for your rifle than this buffer tube or ordering from Primary Arms.

Look no further!


I know it's only a buffer tube but I can't get over how excited I am to have it. It just makes sense why would you look any further. The pic does it no justice. The finish is a deep black and it's flawless. No my AR is not a museum piece it's a tool but I want to be the one that bangs it up and breaks it in. I don't want it sent to me that way. Primary Arms shipping/service is second to none!

A solid upgrade and solution


Very well made tube that seems noticeably more stout that mil spec. This pin retention concept fixed a problem with a customer's lower receiver that had been improperly mfg./threaded (causing the buffer tube to not fully engage the retainer pin). In addition the continuous cradle of the BCG prevents wear.

The Best

by -

Awesome, the anti-tilt feature is bar-none the best. Awesome buffer and worth the cost.

One of the top upgrades for any AR

by -

I fell in love with POF rifles a long time ago and parts like this are the reason why. This buffer tube is one of the best upgrades you can make to any AR, period. The finish is a flawless deep black, and you can feel and hear how smooth the anti-tilt lips make the action, not to mention the reduced long term BCG wear. The extended lips completely enclosing the retaining pin really lock this thing in tight, it's rock steady and even if your castle nut were to spontaneously disappear it wouldn't go anywhere. Not to mention having the POF-USA logo displayed across the back of your rifle is pretty sweet, call me a fanboy but it's not without reason.

Missing carrier support ears and drainage holes.

by -

Received the POF receiver extension still sealed in the blister pack. Without removing it I could see it did not have the carrier support ears or the extra drainage holes.
