anyone have one? i've been reading and researching 5.56mm suppressors for the last year or so trying to decide what i want. the G5 looks like a pretty promising unit. any feedback good or bad? |
|
I've handled one at my C3 dealer and plan to T&E one sometime soon. I like the mount concept, but I detect a little wiggle in the suppressor when mounted. I've heard enough stories about bad alignment and baffle strikes on cans of all makes, and I wonder if the G5 is secure enough. My first thought is the QD spring could be made stiffer. It doesn't take a lot of hand strength to remove the can, so more tension in the spring could probably be tolerated. I also wonder if the spring compresses at all under recoil. Input from G5 owners will be much appreciated. |
size-wise, what is comparable? are we talking M42K length, or SCAR SD length? the poster above said he detected a little wiggle. does this / would this hurt suppression? how solid is the "lock up" to the mount? |
 Tightness doesnt seem to have any effect on suppression, just POI shift. The G5 locks up pretty tight, just not as tight as thread mounts. Of the "QD" mounts its as tight as any of them. |

I am luvin mine! I have run it on 3 different rifles , with three different twist rates , and all of them with 4 or 5 different bullet wieghts.Including a few mag dumps , wet and dry. By next week I will have run it on 3 Ars, a rem700 and an FS2000. The bi-lock is a great feature. My experience with suppressors is still limited , but this gets my stamp of approval , and I am a picky one. |
Who is installing all those bi-locks? |
Not yet, waiting on appoval on a form 4, but can't wait to find out. 
|
My gunsmith does it , while I am waiting/shopping. |
geez, from that chart, it looks like they went larger and heavier with it. i wonder what the reasoning was for that when everyone else seems to be going smaller and lighter? |
+1. i'd like to know the same. |
Please don't run the G5 wet. Gemtech centerfire rifle suppressors are engineered to be run absolutely dry. This prohibition is specifically covered on Page 6 of the G5 manual. On the issue of Bi-Lock (QuikMount) installation, any competent gunsmith can install them properly, provided they are willing to follow the instructions exactly and not get creative. Whoever installs it needs to remember that this is a suppressor mount (and needs to be concentric) and not simply a flash hider (where crookedness doesn't matter). We do offer the mounting service, but it is far faster, simpler, and less expensive to have it done locally provided the installer is willing to do it right. Philip H. Dater/GEMTECH |
Yes Phil , I think we talked on the phone.  I only ran it a little wet the first day of use, with maybe a tablespoon of water in it. I called you the next day , and you told me not to run it wet. After that , I have run it 100% dry , and it works fine. I should also add that every time I have called Gem-tech , 5+ times for orders and advice, they have ALWAYS answered the phone and been very helpfull.

Phil, what is the minimum barrel length that a G5 can be attached to (10.5 with normal FSB and lug), and what is the minimum barrel length you guys recommend/warranty. |
We are most comfortable with a barrel 11.5 inches or greater. Most quality barrels of 10.5 inches are OK, but our level of comfort diminishes to zero any shorter with )rare exceptions). Please remember that the .223 cartridge was designed around a 20" barrel, and when you start getting too short, all you have is a horrible noise and flash generator with significantly impaired energy and ballistics.

What are the warrenty issues if a gunsmith installs the bilock? |
It would be unrealistic to expect any manufacturer to warrant work done by someone else outside the company. The person doing the work is the one to warrant it, and if he messes up, he would be responsible for costs of repair. The manufacturer can repair any damage done, but it would not be free. To use an analogy, if a car repair shop screws up (whether the Ford Dealer or Jim-Bob's Shade Tree Car Repair and Barn Door Company), it is the repair shop, not Ford Motor Company, that is responsible for costs related to correcting the problem.

| I just mailed off the form 4 for the G5 I just bought, so the comments about having a gunsmith install the flash suppressor/QD mount are a bit confusing. I've got a AR15 upper receiver block and a barrel/flash suppressor wrench, so is there any reason why I shouldn't install it myself? I understand the mount needs to be installed concentric to the bore, but wouldn't the threads on an AR15 barrel already be concentric? If not, what is a gunsmith going to do to fix them that I can't do myself? |
There are very complete installation instructions in the G5 manual. You could certainly do a self-install, but if there is an alignment problem you are accepting the risk. I have seen many, many AR/M16 barrels that are nowhere close to being concentric. I have also seen one that had the shoulder several degrees off thus cocking the flash hider. Either of these situations will require gunsmith or machine work to correct. What the gunsmith will do that you cannot is square the shoulder perpendicular to the bore axis, or rethread on centers to make the bore concentric. Personally, for the very reasonable $20-25 Gemtech charges, I would send it direct to them. Their turnaround time is very quick for this operation. |
Actually, we charge $30 plus return UPS to mount and gauge the flash hider/Bi-Lock/QuikMount installation. If you have the needed tools, can follow instructions, and are able to gauge the installation, by all means do it yourself. A cleaning rod is not a gauge, and gauging instructions are in the manual. Lest you think we are getting rich doing these installations, guess again. Although we have this down to a science, we don't even make shop rate. We do the installation as a service to our customers. I would guess that about 2-3% of the shoulders need touching up to be square, and I have seen a total of 3-4 barrels where the threads were not concentric. These are factory threads, and they were both Colt and Bushmaster. Before you get critical, remember that those guys are installing flash hiders (only) and not suppressors. Philip H. Dater |
...and i do love my horrible noise and flash generators.  |
