標題: 換 RA-TECH Steel bolt carrier for WE SCAR [打印本頁]

作者: dennislau1 時間: 26-6-2011 17:56 標題: 換 RA-TECH Steel bolt carrier for WE SCAR

After replacing the Open bolt kit and played for 20-30 mags, suddenly i found there 嘔彈 constantly and the hopup is not working at all. That is when i saw the bolt carrier being deformed.

(Upper is RA tech steel bolt and lower is original WE) Using the finger touching the inside of the cylinder, it seems the cylinder shape has slightly deformed and causeing trouble to retracting of the 飛機.

Also not satisfied with the high cycle of the open bolt, I go to get a steel bolt carrier to replace the original bolt carrier. Quite an expensive purchase actually, over 700 dollars.

However it is not without any problems. The 飛機 retention pin hole is slightly smaller than the pin itself (2mm vs 2.2mm). So i have to drill the hole a bit larger.

Also the size for holding the 飛機 retention grove is too small and cannot insert the plastic thing smoothly. So i have to file the plastic grove down a bit.

Finally for a 7xx dollar aftermarket part, I have no idea why they did not fully copy the original copy, and instead made this location so much shorter.

This maybe the cause on the reason why i broke the charging handle

Several dry runs have to be made in order to ensure everything fits perfectly. I have also sanded the bolt carrier on all sides to reduce friction with the body.

Finally is the installation of the 飛機, which i have customized to reduce power. Afterall the original setting is over 1.5J, way too much for indoor CQB purpose.

The final product - The steel bolt carrier gives high blowback, but one mag can now only shoot 28- 29 rounds. I will have to test more with that.

Final thoughts: on WE GBB - I will avoid models that have alternatives. The M4 Mags are just bad, and the gun's material is just not up for use. For M4 i will definitely not buy WE.
on RA-TECH - Material itself is seen to be of top quality, but the dimensions should be better as this is one expensive aftermarket parts.

But since only WE produce the SCAR, there is no other choices. Also given the simplicity of the SCAR, WE should be able to work out a better design for the gun and minimize the use of aftermarket by the buyers.

Meanwhile we will have to wait and see who else will come out with a better SCAR.

Good experience. You should show WE the problem....... Also, RE-TACX their products just use some so called strong / better material parts and sell for ????? such high price but still without solve the real problem much.........

作者: dennislau1 時間: 26-6-2011 19:18

其實嘔彈是咩原因都未能肯定。不過見個bc 都攪成甘, 唯有換左佢lor.
有時d 野真係寧願d 野賣貴d但耐用d。換左open bolt 都係打左兩三場咋

期實YYE再來應該再整好銅膽個Hop-Up系统 ! SISTEMA PTW隻Hop-Up設計係可以造落支銅膽到! 不過冇人做!

我家的SCAR已染上"豆腐Bolt Carrier變形症"
不想移植原廠Bolt Carrier
又嫌R@的Bolt Carrier
現在SCAR只能閉關掛牆
剛剛上"根sModify" 的官網發現
又有 for SCAR 的Steel Bolt Carrier Coming Soon
如果價位好過台製
未嘗又多一選擇

個bolt成日變型又zip實隻飛機，係因為回鏜彈弓果個圓筒唔夠長做成，
zip長少少試下啦

其買小弟也有做足功課
新槍買回來已即時在圓筒墊厚5mm以縮短槍機行程
先試過用手拉槍機時也是只有剛剛能Bolt Lock 才放心試打
但打了約5匣飛機巳不能正常縮回Bolt Carrier
拆開發覺Bolt Carrier 底部前端己被擊錘的轆仔咬到變型
而最後發現兇手其實係回膛彈弓桿最後面個塊吸震軟膠
每次槍機後退時衝撞圓筒及把吸震軟膠壓扁超過5mm
所以就算墊盡圓筒加厚
槍機行程還是太長而讓Bolt Carrier 底部前端被擊錘的轆仔咬到
所以問題重心還是在那塊吸震軟膠
太軟會令槍機超出行程
但太硬又怕把摺拖底板打爛
頭痛

塞左入去仲未得既...要加多一粒野...就係...

粒野係唔係好熟呢?

咁改係得wor...
除左自己車之外仲有咩替換方法呢..
因為唔識用車機+識都冇機比我用

可唔可以有多D 圖？？？
我想睇清楚小小

水喉膠墊 + 熱縮膠就得

我用緊o個 D 比較硬身少少
再用熱縮膠固定位置，中間個洞仲可以掂唔到 recoil spring

Good

其實我覺得kick 飛機同回堂彈弓關係不太大。反而可能係個飛機同個固定膠有d關係。應該是同個飛機設計有問題
今日向屋企試左一匣都清到匣。但只試左單發。

你知唔知咩係回鏜釬?
我有講係條彈弓有問題咩?

作者: midea1234 時間: 2-7-2011 00:16

請問 c hing 要加幾多 mm
thank you

作者: rYaN 時間: 2-7-2011 04:17

幾MM唔肯定!
點試呢!?
你拆左下身...拉後個BOLT!再放個下身返上去(繼續拉住個BOLT)
睇下個BOLT有冇KICK住!
再睇下係唔係頂住上唔到個下身入去(成功)
最後都要插匣試!再睇下個BOLT條鬼,睇下個啤令有冇行近個鬼頭!

作者: dennislau1 時間: 2-7-2011 10:14 標題: 回覆 17# 的帖子

大家研究下jer. 我指的其實應該是回鏜行程。雖然太長係會打蝕carrier 頭,但而家換左bc個飛機依然不能完全自然回位,仲差小小。遲d補相。
