I've had my share of shorty AR 15s, and I've even built a couple of 5.56 chambered 7" barreled GeBoomenloudens. The HORRIBLE muzzle blast, flash, and velocity loss all combined to convince me that chopping a 5.56 caliber barrel this short goes past any sensible point of diminishing returns. The concussion with 5.56 BALL from all that powder burning outside the 7" barrel, is downright unpleasant.
My current favorite AR 15 is my 10.5" LMT, which is totally reliable and accurate enough [ 2 - 3 " @ 100 yds ]. However, muzzle blast is still excessive, and as reported by my neighbors on the range, is even greater [ SHARPER any how ] than 7.62 NATO BALL out of an 19" M14 shorty. Since I usually do most of my range practice with shorty ARs and shorty M14s, when my muzzle blasting starts echoing around the insides at our covered range, I am quite "noticeable".
For this reason I just mounted one of Joe Dlask's new LeVang ?Muzzle Brakes? ?Comps? on my shorty AR for a trial. Joe tells me he designed this brake specifically for the Ruger 10/22, but it is the standard AR 15 1/2" X 28 TPI, with a bore sized appropriately. So I removed my standard AR 15 bird cage flash hider, screwed the new ?comp? on my LMT 10.5", and shot off some .223, some 5.56 Green tips, and using my CMMG conversion kit, another 100 rds of .22LR ammo.
All of the groups stayed about the same size, and at about the same POI. Recoil and muzzle flip seemed the same. The good news was that muzzle blast to the sides was significantly diminished. With this muzzle accessory, most of the noise now goes out to the front.
So now, my neighbors at the range don't hate me quite as much as they used to.

This Levang compensator was produced by DPMS and it was modified by us for use on 10/22 heavy barrels that have a thread at the muzzle 1/2”-28 tpi. This compensator will help direct the gases on a forward direction away from the shooter. The modifications are as follows: the outside diameter was reduced so it matches the diameter of the 10/22 heavy barrel (.920”). At the rear end of the compensator, two flats were machined in the body, that allow the use of a wrench for tightening. The overall length was reduced to 2”. The final product was bead-blasted and re-blued.
