Awhile back I kept reading some very positive reviews of the JP Silent Captured Recoil Spring assy's designed for the AR rifles. These are designed for both the 223/5.56 series of guns and the 308 sized series of guns.
I installed one(JPSC32-15,pre Gen II model)in my 18" Bison(side charge) chambered in 6.8SPCII. I have approx. 75rds thru the gun now using this spring ass"y. I shoot a fairly hot load out of this gun(85gr Barnes TSX @ >3100fps) and wanted something that would make the recoil impulse feel not as "jerky" and give me ease of follow up shots if necessary. (Now,this is my primary nigh time hog gun).
During install I chose to take out the buffer retainer and it's spring as per the directions. Less stuff to malfunction i figured. I noticed the difference right away. You could blindfolded. There is not a gritty feel. There is NO "twang" and/or spring noise. If you cycle the gun by hand there is simply a very quiet "swish" sound. AND the whole cycle is super s m o o t h e . Pulling the BCG to the rear it seems to use the same amount of effort all the way to the rear if pulled super slow.
My brass still ejected to the 3:30 position only a little further away. The brass looked normal. The firing,extracting and reloading process seems faster. Quite a bit faster. AND quite a bit smoother.
You guys that use your AR for competition should really give these a try. To me this, and a great trigger,makes your AR a great shooter.
I will be picking one up for my 308/AR in the near future. --- SAWMAN
