Bought these on a recommendation
<br> from a friend. I wanted a quality BCG for a new 3 Gun Rifle. I liked it so much after shooting my new rifle I bought a second for my other build.

Great

Got the sons of liberty BCG and and it was a difficult choice between SOL and BCM. Went to the range and put 350 rounds thru it and did not have an issue at all. It performed perfectly and will definitely buy one more for another AR. It was a breeze to clean. Shipping was super fast also.

Fork Yeah!

High quality BCG I bought 2 and they have been great in a BCM and LMT MRP Shovelnose upper. both uppers are 16 inch, but the fit and finish on the BCGS are top notch! these are legit AF buy and enjoy, we all know you're not shooting 10k 556 any time soon... SOLGW FTW buy this BCG the price can't be beat.

Simply Awesome

Let’s just say the package alone this BC came in was outstanding. So pumped that I went with Sons BC over BCM. You can see and feel the quality, also buttery smooth. SOLGW is such a great company. Buy with no worries.

Great product

Everything you would expect from SOLGW. Great BCG cycles smoot and eats any ammo. Get one if you haven't already if you have get a second for other rifles
