These work great. Slicker than greased owl poop.
No problems at all
Looks to be a well made BCG. I needed one for a recently purchased upper without BCG. Have a number SAA parts and have found them to be well made and quite durable. It is slightly easier to clean than bolts with other finishes.
I have purcahsed a few of these and they are great. One is now at around 2000 rounds and no issues! Great deal and great quality, what's not to like! Cleaning is easy and function is flawless. I can'
t determine who makes these but they are a great buy none the less! I think it's time to order a few more for some other builds I am planning!
Very pleased works great
I received an email from SAA and saw that this BCG was on sale. I hesitated for about 10 minutes... I had recently completed a build with a Stainless Steel barrel, and thought that a bright stainless steel-looking BCG would be awesome. I was very happy that my hesitation passed. I bought one, and showed my son the website (and the price). His hesitation was shorter. We are both very pleased with the product. Both ARs cycle cleaner than with the BCGs that they came with. Definitely a welcome upgrade.
Was looking for a nice boron bolt. This was on sale with great price. Would buy another
Wow! So impressed with this bolt carrier group. Beautiful finish, quality components. Best price anywhere! I purchased this BCG for my supressed 300 blackout, the BCG gets so dirty shooting supressed, this BCG has helped the overall functioning of the firearm. I highly recommend This BCG to anyone looking to upgrade their AR platform. I plan to purchase more!
They where good for the money but nothing like the finish on FAIL ZERO BCG !
