Toaster Posted February 9, 2017 Share Posted February 9, 2017 I removed it from my m4 as soon as I noticed. The gun is worth more than this handle. I'm quite upset. It felt nice the few times I used it. This could have been solved with a recess at the base of the handle. It also doesn't have the 3 rotation stop points. Shows me how little R&D they actually put into things. Lots of shortcuts. Shame. Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted February 9, 2017 Share Posted February 9, 2017 Odd. Got a picture of the end of the charging handle where the detent engages? I've used these a bunch and haven't had any problems. I'd let TTI know and I bet they'd replace it. Quote Link to comment Share on other sites More sharing options...
Unobtanium Posted February 9, 2017 Share Posted February 9, 2017 I said it sucked years ago when TTI pimped it on this forum. Quote Link to comment Share on other sites More sharing options...
Unobtanium Posted February 9, 2017 Share Posted February 9, 2017 Ps. The bolt catch roll pin on OPs weapon needs love. Quote Link to comment Share on other sites More sharing options...
benelliwerkes Posted February 9, 2017 Share Posted February 9, 2017 Is the complaint about the loss of 2 mm of receiver finish ? when the bolt is in battery and apparently only when the bolt handle is pushed inwardly. The metal-to-metal contact may well be due to slightest differences in Benelli receiver profile rather than the bolt handle specifications. If the bolt handle was too short as implied by the OP, why doesn't the bolt handle scrape the receiver finish along the entire length of its excursion? It appears that this fit mismatch would have been obvious upon installation of the bolt handle. Alma-Black will camouflage the mark. Quote Link to comment Share on other sites More sharing options...
12508 Posted February 9, 2017 Share Posted February 9, 2017 Just ignore the tacticool crowd and get the KZ ergonomic version. I abused one in a shotgun class doing various drills over and over again with no ill effects to it or the M4. https://www.botach.com/kley-zion-benelli-m4-ergonomic-3x-oversized-charging-handle/ Quote Link to comment Share on other sites More sharing options...
les_garten Posted February 9, 2017 Share Posted February 9, 2017 I just bought one of these couple months back. Mine freely spins, no 3 position detent like the stock one. But mine is well relieved and cannot touch the receiver like the OP's does. Quote Link to comment Share on other sites More sharing options...
sniiped Posted February 9, 2017 Share Posted February 9, 2017 I have one also, with the same mark on my receiver. Mine will actually go past the detent and hit the receiver if I'm not careful when I install it. Quote Link to comment Share on other sites More sharing options...
Evolution Posted February 9, 2017 Share Posted February 9, 2017 Replacing that particular part on an M4 is a waste of money. Stick the OEM part back in and be happy. A seven round mag tube is all that is necessary to mod on these guns along with a couple US made parts to make them compliant. Really people, you don't have to do something to it because the next guy thinks it's better or looks cooler. It's a superlative gun as it is.

Toaster Posted February 12, 2017 Author Share Posted February 12, 2017 (edited) Yeah I'll admit. I'm an car guy, and like to trick things out and improve where I can. If if it ain't broke, fix it till it is! I have plans on sending the thing to Robar once it's all done. I would've bought an H2O but couldn't find one. So I figured I'd send it in after, similar to Strangers "H2O Extreme". Actually picked that up per his recommendation. No biggie. The damage happened in the case. Bolt foward. Compressed. The original bolt handle is significantly harder to compress or remove. The CC tubes ars coming I hear, the Ava mount looks great. Collapsible stock. Scalarworks optic mount. Plenty of R&D, willing to share and prove. Edited February 13, 2017 by Toaster Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted February 12, 2017 Share Posted February 12, 2017 I'm surprised you guys have had so many problems with this bolt handle. The units can certainly be pressed past the detent, which may be causing the finish sear issues. Quote Link to comment Share on other sites More sharing options...
