Griffin Armament M4-SD Compensator

The M4-SD Tactical Compensator from Griffin Armament is a black-oxide, stainless steel military-style muzzle device offering low concussion, flash and excellent muzzle control, as well as compatibility with a number of sound suppressors.
There has been a market for muzzle devices as far as I can remember - flash hiders, brakes, compensators etc. The standard A2 compensator is still the most economical choice, but there are always folk looking for improved performance over the standard. Flash hiders reduce flash signature while compensators or brakes either aim to reduce felt recoil or muzzle jump/movement. The idea is to keep the muzzle as neutral as possible when shooting, so that any movement seen by the shooter is due to his own input. Less movement means quicker follow-up shots, or less need to adjust one's position after firing a shot. Granted, the 5.56mm round doesn't have much recoil to begin with, but if you could make it shoot like a .22 LR, why not? For the most part, muzzle brakes do a decent job of reducing muzzle movement but at the expense of increased side blast, flash and concussion. Then there are muzzle devices that attempt to strike a balance between all the desired attributes, like the PWS FSC556 and Battlecomp.
A new entry into this market is the M4-SD tactical compensator, from Griffin Armament.
Description - The M4-SD is a military-style muzzle device, designed to reduce muzzle rise and offer recoil control, while keeping concussion and flash levels to a manageable level. The M4-SD is named after Griffin's M4-SD sound suppressor, and it's compatible with the Gemtech HALO, SRT Typhoon with Atlas mount, Quicksilver's QD223, Coastal's FDX-FHM and the AAC Omni (basically, any A2-compatible suppressor mount). It's made out of 17-4PH stainless steel, and finished in black oxide.
The M4-SD is the same 22mm (.865") diameter as the standard A2 compensator, and is 1.75" long. The main portion of the comp has a slightly reduced diameter, and has 11 rows of 5 ports/holes drilled into it. The 55 holes are .078" in diameter and have .025" chamfers. At the front are 6 holes, of the same size. The concept is similar to the KAC Triple Tap and Battlecomp, but using holes instead of slots. The comp is closed on the bottom.
The M4-SD was designed to be optimized for use with sound suppressors, and is constructed with thick walls to prevent expansion of the comp inside a suppressor under use, where it's exposed to a very harsh thermal environment. Strength is the reason why the ports are configured in rings, rather than staggering or offsetting them.
The M4-SD can be installed with a crush washer to achieve the correct clocking so that the closed section is on the bottom, but peel washers are recommended for use with some suppressor mounts. I mounted the M4-SD on my Addax Tactical ATAC GPU, which is one of my favourite uppers to shoot. It's a very soft-shooting piston upper, and feels no worse than a DI gun, unlike most other piston guns I've shot.

Blackhole
私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。
Again I went to blackhole this year. It is a little bit disappointing because the entrance fee has gone up considerably. I also heard from exhibitor that booth prices have gone that’s why the exhibitor have also gone down by I would say about 40%.
But it is great to be there again since I love airsoft and my fascination is always there.
Some of the light moment is this guy wearing full battle gear shooting a different kind of shooting machine, complete with an eotech holosight and a sopmod crane stock.
I also found a half scale replica of the Oakley bag I was carrying that day.

Scar Heavy from Tokyo Marui

This is about the new Scar Heavy from Tokyo Marui. although by this time a lot of people may already made a lot of review about it but I decided to post the photos I took of it just the same. and of course a few comments here and there.
In the box: The gun looks great and very secure with two straps of velcro securing it instead of the usual one that Tokyo Marui uses.
The manual is also secure under the black mat. The flashhider looks great as well as the gas block.
The magazine is new design from Tokyo Marui. I also like that they made it with the magazine baseplate. It looked better than the ordinary M14 mag.
Markings still looks good
The usual bag of BBs and a front sight adjustment tool under the TM mini box.
The barrel extension for those who want that carbine look.
