nice rifle

Very nice, Only recommendation is to throw on a Magpul Trigger Guard, They are excellent for those cold trips to the range.

How much length does the M402 add? I know they say 4.2", but I dont know if that includes the falsh suppressor in the original length.

Nice build!

Hows that Pistol grip working out? Is it better than a Hogue?

This build has the special secret feature of a trigger guard, which is held in place at one end by a spring loaded detent, which when depressed allows the guard to be pivoted down, allowing access to the trigger even when wearing the thickest mittens



Holy shit, they need to put that on the military guns too!

Very nice. Sounds like my 10/22 firing CCI mini mags. Throw a Surefire on her and it would be the perfect home defense weapon. Short, handy, and won't deafen and blind you when shot indoors.

Its there, just on the other side. L4 w/Vltor mount. Bright enough for any hallway or room in my house.

It will also work with this if for some reason I need to take the 02 off.

Don't get the 9" rail.
Looks really cool the way the suppressor is countersunk.
Link Posted: 1/23/2006 5:48:59 PM EDT
Looks real nice Steve!!!

Link Posted: 1/23/2006 6:55:25 PM EDT
Mine is better. Too bad I have to wait on paperwork.

Really, that is a great build! You guys can't imagine how much time, effort, and $$$ Steve put into making these SBRs into accurate, reliable, and easily handled workhorses. Upwards of ten barrels were sacrficed, and countless hours devoted to perfecting operation. We have been blessed with 40 degree swings in weather from day to day in the last few weeks. Not good for the sinuses, but great for testing rifles in conditions up to 60, and down to 20 degrees. Unfortunately, I have been unavalable for range sessions as of late.

Steve mentioned moving the gas port forward, and increasing the size. He also brought up the flutes. What he did not express is just what kind of difference the flutes made. Typically, we at Adco, have thought of flutes as instruments used expressly to aid in cooling. Since most fluting is both narrow, and shallow, little weight is saved. However, these barrels have 3 deep, wide flutes that do wonders in cooling, and help in lightening SBRs, or carbines wearing suppressors or krink-style brakes. The three flutes are indexed so that one rides above the 6 0'clock rail, while the other two lay just under the vent holes on either side of the 12 o'clock rail.

Pretty cool stuff. Steve isn't good at self promotion, or conversation, for that matter. But the man can buld one hell of a gun. We are fortunate that he has such an imagination, short attention span, and commitment to the shooting community.

OK, I gotta go call my shrink, too may positive comments...

That is a fine looking weapon. So that's your personal one Steve??

Hey, I wanted to add, I bought the Match Carbine upper and I can't explain it but that thing is as smooth as heck. All these guys were talking about how a midlength is so much smoother and all this, but I'll be danged if that carbine aint the smoothest out of the 3 ar's in the family. 1 Being a 20incher and the other being a midlength recce that steve built. I'm telling you, this carbine is smoother. Why, I don't know. Maybe Steve did something magic to it. It might be that I'm prejudiced too though. Also, I did just a little bit of accuracy testing and it's fairing pretty well too. I got 350 rounds through it. I'm really glad I went with the carbine!!!!!!

Steve,

Very very nice. It's funny but I have a similar build going on in 9mm right now. It will have a basically "permanent" SWR Trident inset in a Troy FF tube.

OBTW, thanks for the excellent service on the parts you recently sent me to support this similar build!

I have to agree with this as well. The hogue is a huge improvement over the standard pistol grip, but the G27 (in my opinion) is better than the Hogue. I've only been using the G27 for a maybe 7 or 8 months now but I've since removed all of my hogue grips and now exclusively use the G27.

Bigbore,

Did you weld up the existing gas port hole in the barrel? Or did you start with a blank?



Thanks

[tree-hugger on] I can't believe someone would want to build something like that!!! What would you ever need such a rifle for??? People like you are crazy and should be locked up!!! [/tree-hugger off]

Very nice build!!! I can't wait on my Form 4 to come back (went pending Jan 4).....


You make criminals envious!!!!

Too damn nice, Steve.
Sounds like a .22lr.
A few questions: How loud is the sonic crack?
Is it comfortable to fire indoors w/out hearing protection?
What is the Db reduction rate for the M4-02?

Db reduction should be between 30 and 32 Db, depending on who you listen to. The baffle stack is virtually the same as the longer, removeable GemTech offerings. This is what I've read on the net, anyway.

I dont think it would be comfortable indoors without hearing protection. Most people, I doubt would want too many rounds through without hearing protection outside. Add the same suppressor to a 16" barrel and its much quiter.
I'm not sure what the Db reduction rate is, Gemtech doesnt publish those numbers.
You'll have to drop me a line and I can meet you at the guys house who transferred the Kimber for you, and you can hear for yourself




Not bad at all. I was expecting the sonic crack to be worse.
I know the 5.56 is not the easiest round to suppress, but the .22Lr like report from an 11.5" is VERY impressive, to say the least.
I might have to take You up on that offer, now that MI is now a Class III friendly state
and My financial prioritys have taken a sudden, and abrupt change

rsilvers tested the unit at 138.8 db with a 14.5" barrel for a sound reduction of 26.1 db total with Q3131A.

The M4-02 should be just over 140 db on an 11.5" barrel and is not hearing safe so you should not shoot it or extended periods without hearing protection.

Out of the 27 suppressors they tested it ranked 5th worst for reduction and 5th worst for first round pop.

Does not exactly jive with 30 or 32 db quoted earlier.

M4-02 is a good can because it is cheap and light, not because it suppresses well. Go to silencertests.com and you can find suppressors for that price and weight that suppress better but they are at least 1.2oz heavier and $75 more expensive.
