Global Tactical Thunder Bolt

Global Tactical has been selling an excellent bolt carrier group (BCG) called the Super Duty Bolt for years now. I have been very pleased with the one that I have in my range/training rifle. It is in excellent bolt that meets or exceeds mil-spec. The Super Duty Bolts were basically hand built by Global Tactical. Now Global Tactical has found a manufacturer who will make BCGs to their specs. This will help keep costs down which is good news for consumers.

The new BCG is called the Thunder Bolt. Check it out at Global Tactical.

Lancer L15 Lower Receiver

Lancer, the folks who make the excellent Lancer L5 magazines, are now bringing to market a new lower receiver for the AR-15 family of weapons. It has a pretty unique feature – interchangeable magazine wells.

The modular magazine wells will allow the user to tailor the size of the magazine opening to their preference. There will be three sizes: Competition (largest), Tactical (medium), and Standard (similar to standard lower). The lowers will be sold in various package deals ranging from stripped to premium with high ends stocks, grips, and triggers.

It will be interesting to see if these take off considering that they are not inexpensive and the functionality may be over-kill for most users. Still, it is exciting to see innovative manufacturers like Lancer continuing to press the limits of the AR-15 platform.

Check out the L15 at Lancer’s website.

Battle Arms Development Ambi Safety Selector

This is a pretty clever new take on the AR-15 safety selector. The Battle Arms Development, Inc. Ambi Safety Selector is an ambi selector that allows the user to choose between several different sizes and shapes of selector lever on both sides of the rifle.

There are good reasons to have an ambi selector even if you are a right handed. For instance, you may have to switch to your weak side in order to clear a corner or you may lose full or partial use of your strong hand. The nice thing about this lever is that you could put a short or slim lever on the side that you do not typically use so that it is out of your way or you could put a larger lever on your weak side to make it easier for your weak hand to manipulate.

If I were to install one of these, I would give the screws a good dose of Loc-Tite and I would suggest that you do as well. Screws always make me nervous and they certainly could be a downside to gear like this. Shooters should always weigh the pros and cons carefully if they ever choose to replace a simple part with a more complicated one.

Issues with the US Palm AK30 Magazines

Don’t put your old reliable Eastern European metal mags or Bulgarian Waffles in storage just yet. There have been some teething issues with the new US Palm AK30 mags. I don’t think it is time to give up on these mags yet, but there have been some major issues in the form of cracked feed lips.

You can’t help but root for a US manufacturer of AK products. Hopefully, I will be able to report here soon that a new improved mag with all the bugs worked out is available. We are pulling for you US Palm.

AK Matt at AK47 Talk has been covering the issues HERE and HERE.

ITS Tactical recently posted an article that may be of some help when trying to determine which, if any, MREs to purchase.

Dwell Time and You

If you own an AR-15 or you are thinking of purchasing one, you should make yourself familiar with dwell time. Dwell time is simply the amount of time that the bullet spends in the barrel after it has passed the gas port and before it exits the muzzle end of the barrel. Too much time here results in an over gassed system which can cause accelerated wear and tear. Too little dwell time can cause short stroking (especially in cold weather). Both situations are bad.

Barrel length, gas system length, and gas port size are key to determining dwell time. An understanding of these factors is especially important when you are looking at 16″ and 18″ barrels. Many people choose barrels based on looks or style without truly understanding the consequences of the choices that they are making.

The military uses carbine length gas systems (about 7″) on 14.5″ barrels and rifle length gas systems (about 12″) on 20″ barrels for a reason. Carbine gas systems on 16″ barrels may be less than ideal since they are often over gassed. Straying outside these norms can have a negative impact on your reliability. Midlength gas systems serve the purpose of shortening dwell time and over gassing on 16″ barrels. Arm yourself with as much information as you can before choosing a barrel!

Here are two excellent discussions of dwell time, its determining factors, what it might affect, and how to tune it:

The Complete Glock Reference Guide

I have been using The Complete Glock Reference Guide for several years now. It contains page after page of invaluable information for Glock owners. It covers everything that you would expect: field stripping, disassembly, assembly, cleaning, and more. The most invaluable information for me has been the tables that detail the parts that all Glock models have in common. I used this to help build an inventory of spare parts for all my Glocks.

All of the information is presented in a very well organized way with plenty of white space and tables. There are tons of clear pictures to guide you through the procedures outlined in the book. It is also spiral bound which allows it to lay open easily on your work bench.

This is just the kind of book that a Tactical Handyman needs on his shelf.
