That's almost 100% the setup I'm putting together, I'm very interested to see how it runs. Any feed back you have would be appreciated.Quote:

Zero issues to report. 150rds of mixed Federal & Winchester 55gr, and 50rds of Federal Fusion 62gr. Various gen3 PMAGs fed great, extraction / ejection was good, recoil was no worse than my Colt 6720 or M4A1 upper. I did have the Super42 spring w/ H2 buffer, which seems to be the sweet spot. Accuracy, though at 27yds, was typical for 55gr fodder. It stacked the Fusion though when I did my part. I have one 10rd group that was dime sized. For me, with my eyesight and a red dot, and basic shooting skill, I'm happy with that.
Overall, consider me a satisfied customer, especially for what I paid with the Black Friday deals.

Got the BKF upper in short order, no pics yet but it looks good. Picked up a used 10.5" QC10 9mm barrel and a cheap handguard off the ARF EE this morning. Just need a hybrid bolt and then I'll start on that project.
So I still haven't settled on what upper I want to purchase for my recently approved sbr. I'm stuck between SOLGW and a PWS 111. I have heard piston guns tend to do better in an sbr roll. I dont have the experience with piston sbrs to confirm or deny this myself.
I don't have the experience either but my understanding is "it depends". IIRC in Ian McCollum's interview with Larry Vickers, Vickers said the short DI guns were beating themselves to death in the constant high round count training done by Delta and that was the impetus for the HK416. I think he said something along the lines of pistons are an advantage in heavy use SBRs or if you're shooting lots of suppressed FA but I may have some of that mixed up with something else.Quote:

ARs are more refined now than they have ever been.Quote:

With the introduction of the pistol arm brace, the popularity of short ARs has exploded. Many are used as suppressor hosts. Black River Tactical has even gone so far as to offer short barrels with gas ports optimized for a specific use, such as 100% suppressed. But of all the short ARs on the market and all the companies enticing customers with better and better mouse traps, there are very few with gas block pistons.
