FR on GB's M14

[miklo]

this is a field report on Sir Gunner's beloved M14...

he gave me the honor of upgrading his m14 this week, parts are as follows:
1. guarder bushings;
2. systema shims;
3. pdi 19o;
4. sir kirdo's brass cylinder head (i believe he is the first to have this);
5. sir kirdo's brass nozzle.

initial chrono of the gun was 300fps ave, upon dismantling the unit (about 23 VERY small screws!), we observed that the selector switch was broken (nothing the trusty mighty bond can fix) & some of the parts are missing. Such as, no spring in the hop adjustment & locking metal for v3 gbx (ung nasa itaas ng v3gbx na slide mo lang na bakal...kapoy english...hehehe). bushings were exact fit, gears were considerably solid XYTi (parang nokia 5110i - i guess it means "improved"). kasing taba ng ca gears (no caliper guys, sorry). after installing the spring, bumigay ung piston body...so hinto muna...

6. element polycarb fullteeth pistonbody (latest buy)

so modding starts again...installed every upgrade part & chronoed it ....350fps! sheesh, nag-upgrade ka pa! something's not right obviously so backtrack again....(23 small screws! whew! kaya pala grabe ang tyaga ng mga nag-uupgrade ng katorse!)...saw the culprit...nozzle needs a little shaving off on the front end....

installed the stock nozzle on the brass cyl...spiked at 410 pero settled at 385 after nawala na ang lube...just a basis....

installed the brass nozzle...spiked at 421, settled at 407...

oh well, i guess this is good enough than the stock nozzle...

i observed na kulang pa ito...kaya pa siguro paakyatin...for now...ganito muna siya.


just sharing... ;D

hmmmm... meron pa naman ako buksan 2 units na kart m14... Though this is a very informative lesson for me, isang lang question ko. Is the brass nozzle any good or much better if I use an aftermarket (yung hi-end) nozzle? ;D

[ROSCOE]

another question sir miks... ung brass nozzle meron bang oring sa loob?

[miklo]

aftermarket nozzle para sa tm14...is shorter than this...i've tried it, sinubukan ko rin ung nozzle ng styr aug kasi un ang pinakamahaba na nozzle....a little liha here & there...di din gumana...umabot na kasi sa point na malaki na ung butas ng nozzle...better to use the stock nozzle...

yan siguro ang trademark ng acm...in between ;D

kaya ung nozzle ni sir kirdo ang closest para sa kart/agm...wala siyang o-ring pero di siya kasing-luwag ng stock nozzle....brass naman so kahit anong friction, di siya mag-hungaw basta lang meron silicone (payts na)...ang katakutan ko lang sa stock cylinder ng kart...sa sobrang kapal (at lalim) nung rubber, manipis na ung "polycarb daw" cylinder, madaling ma-biyak (sp 120 lang ung kinabit ko sa 1st kart na binuksan ko, bumigay na rin...kaya ayun, nag-order na rin ng cylinder & nozzle kay sir kirdo)...

[gunnerbunny]

dapat bayaran ko ni kirdo ani advertising ni bah........hehehehehe!! ;D

i can see it

Gunnerbunny only uses KIRDO'S
"if its not kirdos, its nothing"

hahahhhahaa!!! ;D
