The best BCG for the price!
I recently began purchasing from AR15DISCOUNTS.com after a long time of using other sources. This was just one of may items I have chosen over just a few weeks and it is flawless. This BCG is extremely well made. The Bolt mates perfectly to the barrel. Very precise machining. I would definitely purchase it again! The term "You get what you pay for" does not apply to this website! Utilize the discounts and deals!!! Simply awesome!
BCA Bolt carrier group...
I have my BCG installed in an Aero upper and lower. It is shooting very well from my 223 wylde averaging 1/2 in MOA at 100yds. Can't say enough good things about the guys at AR15 discounts, great prices, cheap shipping and great service. Will be purchasing a lot more products from them in future AR builds. A+++
So far so good!
Have run a little over a hundred rounds through new build with this bolt carrier in it and so far have had no problems with the Bolt Carrier Group. Can't say enough good about AR15DISCOUNTS.COM, I've made several purchases from them and its been same day shipping, packaged well and good quality parts.
This BCG will be used on a new 7.62X39 rifle
Just swap out the firing pin and install a new extractor spring. Already fired it a bunch in a different lower and love the 7.62X39 round in many rifles. I prefer them to 223/556 especially on a short range rifle with 16" barrel. BCA products are high quality for low dollars ! Many people spend way to much money for parts they don't even need or capable of using. Lots of unnecessary junk out there these days. KISS !
