This is the first JPFC-1 Iíve done and Iím really impressed with the quality. The instructions were clear and complete and made the process straight forward. I now have an AR-15 in 300 BLK that has become my favorite rifle.
The new buffer system really works. I have never really liked a light carrier until combining it with the new buffer. For light loads I have been running all heavy carrier and buffer components and low gas pressure. Worked great for the 3gunnation speed courses but not so much for my fast 69 gr. loads. For 69 gr. at 2800fps plus the heavy carrier and light buffer seemed best.
