Re: 18" midlength and a 762sd?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: BookHound</div><div class="ubbcode-body">I run the DPMS heavy two-piece buffer with standard carbine springs in all my suppressed SBRs (11.5" barrels). In my 14.5" M4 I am also running that combination of spring and buffer. In my 16" suppressed ARs I am running H2 buffers with standard CAR springs. I use GasBuster CHs on all my ARs. The GasBuster is forged, not pot metal. You won't bend or bind the GB CHs like you can a standard CH.
Wolf ammo is under powered compared to mil-spec M193 by ~100+ FPS depending on barrel length. m1, if that POF won't run unsuppressed you might try more powerful ammo and I bet you will have better results.

Thanks for the advice Mark! I was encouraged that even the wolf ammo would cycle my gun even with the extra power spring and heavy buffer. I really dont care if it wont cycle suppressed because 1) shooting unsuppressed just is not that fun and 2) due to the neighbors I really cant shoot unsuppressed anymore. I keep the standard buffer spring and buffer in my range bag, so if push came to shove I could just switch it out.
I'm loving the 762SD and am anxiously awaiting my sparrow!! Thanks again Mark!
