Been wanting to join for a while just got down to doing it. I have been building my own AR 15 now for 3 years found BlackHole Weaponry about 3 year ago when I started to building my own, and so far have used them on all my builds and looking forward to using them on more builds to come.
Here are the two I have done now, I just finished the 24 in barreled one yesterday. I takes me awhile to finish a build, I get parts as money allows. Both are built on Seekins lowers and uppers both using BlackHole Weaponry barrels. The 16in barreled gun is set up for 3 gun type shooting. It is chambered in .223 wylde very fun gun to shoot very fast. The other gun 24in barrel I just finished building this weekend. It is a bench gun I really like sitting on a bench and try to put a group in one hole, really looking forward to seeing what this guy will do on the bench. It is chambered in 6x45.
On the 6x45 I ordered 60gr Sierra Varminter, simply because their was not much to choose from, and felt they where the best they had in stock. As far as powder goes I went with Benchmark for 50 and X-Terminatoer for the other 50. I had the powder on hand. Haven't been able to shoot yet time and weather has not be on my side, but will update when I do. Both primed with Rem 71/2 BR primers.
