FINALLY had a chance to get to the range and do more than just try to figure out where the controls on the AR were located. (Previously, I had less than 100 rounds through it). Got out, sighted in the Core15 AR, and got used to the Tactical Link Battery Assist Lever. On a previous link, I had asked opinions of the "BAD Lever" from MagPul, and those who used them on their AR's. Due to a sale from Tactical Link who makes a similar device, I picked up their version. First - we ran over 300 round through the Core 15. I used a combination of PMC brass and also reloads from Freedom Munitions. That entire time, I had one failure, and that was a doublefeed/fail to extract. Most likely caused by my failure to make sure the mag was seated fully. Accuracy, with iron sights (Magpul buis) was acceptable, with most of the couple inch spread due to my long absence from rifle shooting and getting acquainted to the AR platform. The instructor seemed to think the rifle and I did just fine for one of the first times out.... and REALLY the first time doing more than just pulling a trigger to get the feel for it. (As mentioned, only a couple mags were run through it previously). The Tactical Link Battery Assist Lever works just as promised. The installation took maybe five minutes, (most of that was due to trying to get the recommended thread-lock on to the small screws). It appears to be very well made, and while I am just getting used to the whole AR platform, I love being able to operate the bolt release with the trigger finger. There were no failures of any type caused by the addition of the TacLink BAL. Over all, any questions I had about the Core 15 - (due to the steel ammo not extracting and causing jams) - have now been completely dispelled. It is still early, in my shooting time with the AR, but I think it will do exactly the job it is meant to if SHTF. An "I Kick Hippies" sling plate is on the way, along with a MS3 sling that I picked up on sale at Amazon. Will add those .... (it would have been nice to have had the single-point sling for some of the exercises that we were working on yesterday). A red dot like an Aimpoint or Eotech is defiitely needed to increase the utility of the AR and make the shots easier and faster. The bad-guys would have definitely been out of commission even using the buis..... but... that considerably faster acquisition with the red dot will be nice. Over-all, extremely happy with the Core14 and the Tactical Link Battery Assist Lever. For the guys who responded earlier, thanks for the comments on the battery assist... it is a welcome addition. Pics to follow after I clean the AR in a few minutes.
