Had a nice time sighting in / function testing a couple of my newer AR’s at the range the other day. I typically shoot on private land but bench shooting is a good way to get your guns out, put some rounds through them and make sure they are running good. For the most part there were no issues but any AR builder will tell you it only takes one small issue to throw a monkey wrench in there.

The rifle has an upper built by CIV Tactical using receivers are from Tactical Firearms Solutions. CIV Tactical used their excellent 18″ SPR barrel and Matched Bolt that are known for getting some extremely low sub-MOA results. I used an older Bolt Carrier with the supplied bolt and figured everything would be fine. When the rifle wouldn’t eject a single round I knew there was something going on. Instead of just giving up and using the other AR I brought I decided to try to figure out was the issue was. After trying 2 different lowers, 4 different mags and 2 different types of ammo I decided to try a different BCG. Swapped it out and it ran like a Sewing Machine. I know the Matched Bolt is good as it was test fired with that exact Bolt so it’s pretty obvious I can narrow it down to the Bolt Carrier such as a leaky Gas Key. Looks like I threw in my own monkey wrench.  LoL  

The point is if you think logically through your failures and start eliminating possible issues, you can quite often move past the issues with the rifle and still get in some good trigger time. Oh, and bring some tools and small parts with you when test firing a rifle for the first time.  :)

The rail on the SPR is a Parallax Tactical FFSSR rail. It also has an ATLAS Bipod with ADM mouth and the Stock is the LUTH-AR MBA-1 that you can buy from The AR Pistol is all AERO Precision with an Odin Works 10.5″ Barrel, Primary Weapons CQB comp and a KAK Industry Super Sig Tube. Both guns have Vortex Optics…optics.

AIM Surplus v2 Black Nitride BCG – Improved and In-Stock

Posted on June 2nd, 2014 by ar15news

The AIM Surplus Black Nitride BCG is definitely one of the nicest BCG’s I own. I’ve been using one for I think about 4 months now with absolutely zero issues. It features an 8620 enhanced carrier, a Billet Machined 4140 Gas Key and the entire BCG is coated inside and out in Black Nitride. Black Nitride is very slick and easy to clean but is much more durable than most other BCG coatings. I have the original version of this BCG which had a 9310 Bolt. This new v2 BCG has been upgraded with a C158 bolt which is something I know a lot of people are pretty picky about. AIM Surplus just received a new shipment of these at an unbeatable deal. While they are still in-stock they are just $99.95 with FREE SHIPPING in the lower 48 States. Purchase one (or five :) ) at

NEW!! KAK INDUSTRY LR-308 Nitride Bolt Carrier Group

Posted on May 20th, 2014 by ar15news

I’ve mentioned it before that I really think this year is going to be pretty huge for .308 AR’s. We’ve seen a few new .308 receiver sets come out with more to come later this year. We have also seen a couple of new .308 rail systems introduced as well. What we haven’t see is a nice high quality BCG for a decent price…that is until now. A few months ago my friends at KAK Industry told me they would be working on having a very nice LR-308 (DPMS) BCG made and from what I’ve seen, this looks like not only a very nice BCG but also a smoking good deal. The new KAK Industry LR-308 BCG is Nitride coated and features a 9310 Bolt and 8620 Carrier and will work with DPMS style receivers. The best part is that this quality BCG is priced at just $180 which is an awesome price for a .308 Nitride BCG. If you need a new DPMS pattern .308 BCG, check this one out at

Check out the pics and details below, then head on over to Predator Armament at the links below to purchase yours before they’re all gone.

On Sale!! Rainier Arms NiB and Phosphate 5.56/.223 Bolts

Posted on January 30th, 2014 by ar15news

Out of all of the different parts of an AR that can let you down and fail during a class, range session or worse, the bolt is one of the most common parts to have issues. Could be bad gas rings, extractor issues, broken bolt lugs, etc. Most issues are fixable but its always nice to have an extra bolt or two with you just in case. Rainier Arms has a couple of really nice bolts on sale right now. One is a black Manganese Phosphate & MP Inspected 9310 bolt. The other is basically the same thing but it’s Nickel Boron coated. If you need a good quality bolt you should definitely check these out while they’re on sale at the links below.
