Save money, get this instead of silent captured.


Save yourself $100 by getting this polished spring instead of the silent captured spring and put the money into a hydraulic buffer or a nice muzzle device.

very nice


You can tell just by looking at this spring it is better than your run of the mill buffer spring. It's quiet, and I feel like it should last awhile. I'm running mine with a 3 oz. buffer and low friction BCG..

Great product!


Did just what it said.. along with the Daniel Defense buffer was a great combo!!

Buffer spring


Excellent quality, fast shipping, great customer service

Quality part, great service!


Extremely happy with the quality and price of this spring, would highly recommend to anyone doing a custom build.Delighted with the price and excellent service I always receive from PA.

great product


fast shipping definitely quieted the noise from each shot.



For something so simple it seems to make a significant difference in the feel of my rifles action. Maybe it is all in my head but it does feel nice.

This is a buffer spring


Got my spring today; four days after ordering. Can,t beat Primary Arms for service. I went right out to the range to try it out. Performed 100% as described;quieter with smother recoil.

Awesome upgrade


I bought this buffer spring after reading a lot of reviews. Perfect upgrade, quality manufacture. Easy install with no modifications. I lightly coated it with CLP. SO much quieter than than the stock spring in my S&W M&P 15. Great price and fast shipping as usual.



I use these on every AR I own. Quieter stronger longer life span and just a satisfying finish and quality.
