Most Helpful Positive Review Bitchin tube
The quality is amazing. I have it in my AR10 build with the primary weapons MK216 upper however i did swap out the buffer for the PWS buffer. The braided buffer spring is well made and suited well for my application.
Most Helpful Negative Review Meh..the buffer tube is no different than milspec
Assembled a rifle using all top tier products, purchased this kit. Save your money, the spring and buffer are great... the tube.. youre paying a lot extra for the color, the tube itself is no different than milspec.

Spring great - tube is low quality

by Petey, Verified Owner from MA, United States Written on May 20, 2025
My buffer tube looked like it was found in the middle of the road. Then finished. There was no damage to the finish, just the metal behind it was completely dinged and dented before the finishing process.
I reached out to Geissele, sent them photos, and they sent a replacement / mailed the old one back. Great customer service from Geissele, but the fact that this got thru QC made me lose me as a customer. There are other reviews stating the same. The replacement was much better, but still not perfect.

The spring was awesome. Customer service was awesome but for such an expensive price tag I expect a superior product.
